Agility Factors’ Analyses Framework in Project-Oriented Organizations through a Sustainability Approach in Large Projects Case Study: Isfahan Municipality

In recent years, the project management concept is coupled with sustainable development. In terms of profitability and adapting to environmental changes, generating value for the customer and responding to market needs is a challenging issue. To gain profit and success, a project should adhere to agility factors. With respect to the importance of project execution success, corresponding to the sustainability dimensions and by developing agility parameters, this study provides a framework for clustering and analyzing “large projects” based on agility factors in project-oriented organizations through a sustainability approach and by applying Quality Function Deployment. To this end, critical factors of project success and then agility factors of the projectoriented organizations have been identified. )ereafter, the importance of these two major components has been measured by executive managers in Isfahan Municipality and academic experts. Afterward, the agility factors’ weights have been calculated based on extracted sustainability factors’ weights, which have been gained according to the project’s critical success factors and by applying quality function deployment. By determining the agility factors’ clusters in the project-oriented organizations and calculating their importance weights, the first cluster that contains project communication management, organizational culture, and contracts management gains the maximum weight of importance.


Introduction
In today's business world, in many projects, considering the very high level of uncertainty in all aspects of the activities, priorities, and latencies, activity connections, and also resources correlation, applying the traditional techniques and instruments in project planning is a hard task. In such cases, mere project planning improvement would not yield satisfactory output. For any type of project, an agile model can promote quality and productivity in a specific time and resource framework [1]. e purpose of organizational agility (OA) as a major contributive dynamic ability is for realizing the environmental changes and respond effectively and efficiently to the changes therein. Being engulfed with environmental, highly dynamic, complex, and uncertain changes, organizations face serious threats as to their survival in a highly competitive market. Such business atmosphere being equipped with mechanisms which allow the organizations to respond appropriately to the identified changes will directly be connected with better performance in order to taking the new opportunities and resources in a competitive world.
us, agility is a concern for the survival and success of the organization [2]. Applying the principles of agility to the project as an interim organization is a necessity to deal with environmental uncertainties. Agility is mostly concentrated on the project implementation phase. is approach focuses on the accuracy of planning with respect to the details of planning, better risk management, and more customer affair on its agenda [3].
Innovative and sophisticated technologies have introduced dramatic changes in industrial products and social services [4]. Project management is obligated to manage both the simple and complex activities through modern approaches that are more efficient than the traditional approaches. A project manager seeks to complete the project within time, cost, and resources framework and by generating value for the client [5]. e project management system faces serious and expanding challenges as to value generation response to changes and profitability in business environment. To overcome this challenge, the project needs performance agility. In this century, achieving sustainable development is a blanket and essential challenge for all organizations. Sustainability is a concept on which the researchers and entrepreneurs concern in order to improve and integrate it with the field of project management at different social and business levels [6]. Sustainability is defined as an innate potential through which the long-term, resource-related risks, fluctuations in energy costs, debts, product costs, and pollution are reduced and the waste management is improved. e equilibrium among economic development, supervising environmental issues, and social justice is another definition of sustainability [7], provided that the importance weights of all three fields of economy, environmental conformity, and social balance are considered as equal [8].
e objectives of promoting economic growth, social health, and rational natural resource utilization cannot be actualized without considering the effects of the mentioned components. As to organizational success, sustainability would provide balance and harmony among these three components. is concept is named triple bottom lines (TBL) and offers different values and perspectives to measure the success of organizations in the three areas of economics, society and the environment. e three main components of sustainability are population, world, and profits. Profit is directly related to economics, population contains society and the organizational environment, and the other component modifies the environmental consequences.
e first component consists of the economic environment, and the second is the environmental effects caused by the organization's activities [9]. e increase in the projects' success depends on the managers' improvement in approaches towards the project objectives. Rational decisions drawn by management are highly contributive in project management and the outcomes therein [10]. For this purpose, project management, the core operations of a business, is not separated from sustainability concept [11]; consequently, the field of project management requires project managers to be fully responsible in project sustainability (Silvius and Brink, 2012). e products, services, technologies, projects, and organizations each on its own constitute a sustainable system. According to the project complexity, to deliver the project results subject to sustainability conditions, the necessary instruments and techniques must be properly coordinated [12].
Dynamism in today's economy requires projects that would introduce major changes in people's daily conducts. Due to the current global crisis and gradual resource depletion, as we go forward, project managers are obligated to develop new and innovative perspectives on sustainability and devise measures to achieve the appropriate levels therein. As to time, the nature of the project is periodic and to status is discrete, while the nature of sustainability is unified. To achieve sustainable development, the project activities must follow economically transparent, socially acceptable, and environmentally safe pattern [13]. Project managers often try to improve the issues related to measurement, success, and factors influencing the project performance and seek to improve them [13]. In project management perspective, the critical success factors consist of features, circumstances, and variables, the effect of which on project success are oriented towards sustainability [14].
A brief review of the related literature, in the context of modern business, would reveal the importance of agility, as a key approach as to adapting to the changes in the business world, responding to the customer and generating value therein, in project-oriented organization. Expanding sustainability, that is, observing its principles with respect to resource utility, which should correspond with the credible sources of project management, is essential. Depending on the features, a large project is a type of project that typically has a longer duration (it might be run for more than six months), larger teams of staffs (include more than 25-30 members and even may require the support staff), greater budget and resource allocation, and more tasks complexity, including many tasks having to be done concurrently. A project-oriented organization that manages and executes large projects can be a complex network with high rate of interactions. Hence, the complexity of such systems leads the organization to be agile while they are following the sustainability principles and manages the projects on the basis of critical success factors of project management.
In this study, a framework is proposed for analyzing agility factors in project-oriented organizations with a sustainability approach in big projects by applying quality function deployment (QFD). Identifying agility factors in project-oriented organizations based on the main project success and sustainability factors is a major step in evaluating the project, based on the agility and sustainability approach, which in turn would promote adaptation to the changes in business environment and customer demands. Determining the factors' weight and their clustering in determining the important clusters, which would contribute in planning and goal setting, is essential. is can be accomplished by applying the principles of agility and sustainability components.
is article is organized as follows: the literature is reviewed in Section 2; the project management is explained in Section 3; agility in project-oriented organization is introduced in Section 3.2; the sustainability is discussed in Section 3.3; QFD is applied in Section 3.4; clustering is analyzed in Section 3.5; the research method is detailed in Section 4, the framework is implemented in the subject organization in Section 5, and the article is concluded in Section 6.

Literature Review
To review the research literature, the connected researches have been found based on the keywords and the journals 2 Complexity with the related issues. e select studies run on the main factors of project success are tabulated in Table 1, the select  studies run on sustainability are tabulated in Table 2, and the  select studies run on organizational agility are tabulated in  Table 3. What is deduced from reviewing the related articles is that in today's competitive and changing business world, customer satisfaction is accredited to the organization credibility, quality and speed in response, and agility in project performance. Project-oriented organizations are fully aware of the need to incorporate agility dimensions in project management if adaptation to changes in the environment and response-specified time, cost, and resources are sought. Organizations are obligated to assess the resource planning and the effects of a project as to its economics and profitability, with respect to social dimension next to its effects in environmental sense to correspond with sustainability.
e different aspects of organization and management approaches as to resource allocation and planning for project control, resource protection, environmental effects, economic performance, and social effects of the project are subject to direct effect of sustainability.
Identifying the agility indices and dimensions in projectoriented organizations, based on accurate infrastructure according to the critical success factors of project and the dimensions of sustainability in three areas of economic, social and environmental therein, has been somewhat neglected. In this context, while evaluating the project based on the mentioned factors, the project manager should strengthen the weak indices and generate value, respond to the customer and meet his/her satisfaction, if achieving sustainability, profitability, credibility and social prestige and effects are sought. is in turn would allow successful performance to assure environmental and social sustainability. In all these efforts, though the project was delivered successfully, still the agility aspect is missing in the run studies.

Project Management.
A project consists of human and nonhuman resources, in a temporary organizational framework with the objective to accomplish a specific task [5]. Organizations, today, perceive a project as a manner of organizing tasks. In most industrial, commercial, and governmental organizations, project management is perceived as an instrument to accomplish objectives [30]. e project assists the organization to define and select a set of activities that would generate positive results therein. is phenomenon can be applied in economic, marketing, or technical areas. e project manager is obligated to manage the project through a set of instruments and methods without disturbing the regular routine operations of the organization. Project management activities consist of defining task requirements, planning and scheduling task implementation, allocation progress, monitoring, and keep project planning online. As to project delivery, the responsibility of the project manager is to have met all budget and desired operational and quality standards [31]. Project management can be considered as a temporary effort in separate fields of activities with a specific beginning and end time. Given the existing global economic status, projects must be managed and controlled in a periodical manner. Time, cost, and objective achievement level are considered as the indices of success or failure for organizations that should be supported per project beginning from the structure to the budget. Supervision and control in the implementation phase are also necessities [16]. Project management as an effective controlling instrument is expressed in multiactivity endeavors [32].

Agility in Project-Oriented
Organizations. Today, organizations face varying, dynamic, complex, and uncertain circumstances in these highly competitive markets that pose a threat to organizations [2]. e innovative and sophisticated technologies have introduced dramatic changes in industrial products and social services [3]. Business and management models are essential to support Industry adoption and foster sustainable value creation and competitiveness [4]. e need for an efficient management strategy is evident [32]. Organizational agility enables an organization to understand the environmental changes and provide an appropriate response as to adapting it as a management mechanism [2]. In a sense, these environmental features are the challenges confronting project management [33]. e principles of project management based on traditional techniques are based on regular planning and control practices. Developing an integrated network, consisting of customers, suppliers, supervisors, authorities, and political institutions and competitors is a proper manner of responding to environmental changes, something impossible in traditional project management format.

Sustainability in Project-Oriented Organizations.
e ongoing major changes at global scale have made sustainable development an important strategic measure. Sustainable development seeks to protect, develop, and balance economic, social, and environmental objectives to the available resources to assure the comfort and convenience of the generations to come. e correlation between these objectives and resources is high and important. Today, next to economic values, countries must consider the social benefits and environmental consequences as well. Climate change threatens the future significantly to a certain extent. e natural resources are depleting recklessly, that is, accessing them will be difficult if not impossible for the next generation [34]. Nowadays, organizations define their activities and business as projects and seek to improve their success. Drawing managerial decisions are contributive in project management and its outcomes [10]. Sustainable development addresses humanity's aspiration for a better life while observing the limitations imposed by nature [35]. Dynamism in today's global economy is based on the available projects with the objective to make major changes in people's lives. e current global crisis and extending resource depletion force project managers to develop innovative perspectives on sustainability and assure its continuity. e nature of any project is temporary and discrete, accomplishable through different techniques and methods. Sustainability is not an isolated concept, and it is achieved by Complexity applying project activities run in continuous and transparent economic, social, and environmental context [13]. To deliver a project yield subject to sustainability, the required instruments and techniques should be in accordance with the complexity of the project [36]. Sustainability theme is involved in the integration of the three aspects: economic, social, and environmental aspects, which extends in project management and project delivery, followed by enhancing the project system and the management therein [37].

Quality Function Deployment.
Quality function deployment is one of the qualitative tools contributive in providing services and producing products that would meet consumers' requirements. As one of the new methods in engineering, quality function deployment begins from running studies on market and identifying consumer services while identifying users' demands and seeks to apply them in the design process. e basic insight of this method is to convert the qualitative features into technical features, production processes, and requirements, by applying four matrices, in which the house of quality is the most important part. is matrix has a number of numerical inputs, which after the qualitative identification of the features, statistical methods will be applied to calculate the relative importance of the features on the basis of the consumers' opinions and experienced people ideas [38]. Hence, QFD promotes the systematic translation of customer needs and requirements into design requirements and evaluates alternatives and their impacts [39].

3.5.
Clustering. Clustering and classification are among the most efficient methods in data analysis. Extracting the patterns through grouping individuals and variables is one of the main objectives consisting of many methods and patterns applicable in different scientific fields because human beings when encountering complex issues instinctively seek to compare and divide the given data as different groups. ese methods are applied in different scientific fields like medicine, biology, management, planning, data mining, information discovery, and new structure in speech and images and environmental and natural sciences [40,41].
Massive data, next to being beneficial for organizations and individuals, are problematic when it comes to their analysis. Data mining techniques is a solution in extracting beneficial information and correlations therein. Clustering, with its different methods, is one of the powerful instruments to forces these analyses. Identifying clusters or areas with dense population in a multidimensional data set through different techniques and algorithms is one of the Determining the CSFs in project management in a comprehensive framework Statistical tests e connection rate between CSF and project functionality is measured and a comprehensive method consisting of project management, methods, human factor, external issues, and project-related features are presented 6 Abdulrahman et al [5] 2014 Determining the essential features in project success and the techniques that lead to project management success -Project management theory, project systems, and the CSFs are addressed 7 i and swierczek [20] 2010 Measuring project success based on CSFs in project management and run case studies in Vietnam

Regression analysis
Completing the project life cycle that is directly related to positive relations and success. In the project execution, the external consistency affects and organization support is compensated for 8 Naoum et al [19] 2004 Identifying the critical and noncritical factors affecting the project success in big construction projects -A management led by project and execution management 4 Complexity major issues in multidimensional data analysis. Finding the proper clustering algorithm or/and the most optimal clusters, in a reasonable time, is one of the major challenges in this field [42].
Clustering consists of grouping similar samples into one data mass. e essential point here is data distribution into different K groups with similar data and the same for the dissimilar.
is difference is defined based on distance measurement criteria. Compared to grouping, clustering is an unsupervised grouping process, where the groups are not predefined. Clustering is an indirect data mining operation [42].
In most data mining methods, like the decision trees and neural networks, the process begins with an educational set through which it is sought to devise a model that would make the data in segments and then predicts the appropriate set for a new data. On the contrary, in the clustering, there exist no initial group and the variables are not divided into two independent and dependent groups. In clustering, the focus is on groups of objects that are similar, which when Assessing the management and the aspects of combining project management and sustainability -Organizations' awareness to know the value of sustainability and to achieve sustainability dimensions in practice 5 Amiril et al [25] 2014 Evaluating sustainability factors and project performance in transportation infrastructure -Sustainability factors and project performance can be fit in environmental, economic, resource utility, and project management categories 6 Silvius and schipper [26] 2014 Assessing sustainability as one of the project management competencies and analyzing the gaps therein among the present project managers -By identifying this gap, procedures are proposed to minimize it in addition to introduce new measures and standards in this context as to organization sustainability Assessing the agility and sustainability concepts as contradicting or complementary concepts -Generating value for customer and adopt it with the environments changes next to seeking sustainability in both the contexts Complexity 5 discovered, their behaviors can be identified better, indicating better decision making [43]. In hierarchical clustering, clusters are expressed as a tree named dendrogram. ese algorithms can be in up-down divider or bottom-up adder format, where, the divider must specify which two clusters are divided into two parts and how is this done, while in the additive, the algorithm begins from one cluster and then, the two clusters merge to obtain a make a throughout cluster [44].

Methodology
Project success depends on the delivery of the service and product, creating value for the customer while adapting to the changing world of modern business. Next to the economic approach, the sustainable development that covers the project revenue and profitability, attention must be directed on environmental consequences, resource protection, and the project performance in the social dimension.

Phase 6: measuring the importance of project management critical success factors, sustainability factors, and agility factors in project-oriented organizations Step 4: this measuring consist of three approaches where a questionnaire based on project management and academic experts' opinions is devised as the instrument.
(1) Determining the project management critical success factors' importance weight in project management: through the devised questionnaire based on the Likert scale (1 to 5, that is, a low importance to high importance), which has been distributed among 13 project managers and university professors in this field with 7 years of experience and published scientific articles.
(2) Determining the importance weight and agility factors in project-oriented organizations: the same procedure above is followed.
Step 5: measuring the importance weight of factors in all three approaches through the devised questionnaire based on project management experts' viewpoint in the field of opinions in Isfahan Municipality.
(1) Determining the importance weights of the project management critical success factors: it has been determined based on the project management staff viewpoints and through the questionnaire with Likert scale (1 to 5, that is, low importance to 5 high importance), which has been distributed among 52 staff members. (2) Determining the importance weight of agility factors in project-oriented organizations: based on the project staff point of view and through a questionnaire with Likert scale (1 to 5, that is, a low importance to 5 high importance), which has been distributed among the employees in this field, including 52 staff. Table 9 shows the geometric mean of agility factors' weights in projectorient organizations.
Phase 7: calculating agility factors' weights in projectoriented organizations based on project management success and sustainability approach In this phase, the agility factors' weights are calculated based on the extracted weights of sustainability factors according to the project management critical success factors, and then, agility factors' weights are calculated based on sustainability factors' weights applying QFD.
Step 6: calculating the sustainability factors' weights based on project management critical success factors by applying QFD For this purpose, the house of quality matrix is applied to determine the relative importance of sustainability factors based on project management critical success factors. e house of quality matrix is configured to rank sustainability factors based on project management critical success factors and to determine the relative weight of sustainability factors, which are detailed in Table 10.
Step 7: calculating the agility factors' weights in relation to sustainability factors' weights in projectoriented organizations by applying QFD e house of quality matrix is configured to rank agility factors based on stability factors and determining the relative agility weights' indices in project-oriented organizations, which are shown in Table 11. For matrix columns, agility factors are also considered in project-oriented organizations. e QFD matrix designed by the experts is completed, and its geometric mean is inserted in the matrix cells. By multiplying the stability factors' weights in each one of the columns and normalizing the  Elimination of unnecessary in project phase planning Communicational coherency rate in the project 3 Strong and orderly project staff communication 4 Providing the grounds for consultant communication with the beneficiaries 5 Access to valuable data on time 6 Access to classified database 7 Sharing knowledge and information in the project 8 Organizational culture Allowing project managers and staff to draw decisions 9 Organizational perspective of the project management 10 Decentralized decision making 11 Project management Project management transparency 12 Accurate management method execution 13 Accurate management method execution level 14 Applying new management method 15 Applying proper project management 16 Leadership through brisk managers 17 Project scheduling and control Project structure to project requirements' ratio 18 Accurate short-term planning 19 Proper scheduling with respect to accessible resources 20 Accurate predictions of project requirements 21 Simulations execution of activities 22 Project schedule modification 23 Provisional modification upon need Providing the means for project agility 54 Providing motivation in the respectful teams 55 Providing team work 56 On-time salary payment 57 Secure employee satisfaction 58 Employing skilled staff 59 Employing multifunctional staff 60 Prioritizing continuous training of the team members 61 Promoting team objective orientation 62 Proper task assignment 63 Focus on consumer Respecting customers' ideas 64 Beneficiaries involvement in contract negotiations 65 Customer interests' consideration Reducing construction and facilities installation costs [22] 10 Complexity results, the agility factors in the project-oriented organizations are obtained.
Phase 8: clustering of agility factors in project-oriented organizations based on weighted factors obtained from three weighting attitudes In this phase, the agility factors in project-oriented organizations are clustered based on the weights obtained from the second phase, according to the project management and academic experts' opinions and the weight obtained from the third phase by solving the QFD matrices. Table 12 shows the weights of agility factors based on the three considered attitudes.
Based on the weights obtained in the second phase and the results and the weights obtained from the third phase by solving QFD matrices, the analysis details for agility factors in project-oriented organizations are tabulated in Table 12.
Phase 9: clustering the agility factors in project-oriented organizations based on weight indices obtained from three weight approaches In this phase, the agility factors in project-oriented organizations are clustered based on the weights obtained from the second phase based as to the project managements' point of views and academic experts and the weight obtained from the third phase by solving       QFD matrices, and therefore, they clustered through a hierarchical model.
Step 8: clustering the agility factors in project-oriented organizations based on weight indices obtained from the three approaches At this stage, the agility factors are clustered through the hierarchical clustering method. e yield dendrogram is shown in Figure 2. Accordingly, considering the similarity coefficient is ˃95%, agility factors in project-oriented organizations are located in five Contractor's management 9 3 Technology 10 4 Project IT 11 4 Human resources 12 5 Focusing on consumer 13 Dendrogram using Complete Linkage Rescaled Distance Cluster Combine  clusters, and the clustering details therein are tabulated in Table 13.
Step 9: determining the importance of the agility factors' clusters in project management based on the member factor of each cluster. In this step, based on both the results of the previous step and the weight of clusters' factors, the importance of each cluster is determined, and each cluster's rank is determined according to their importance value. As observed in Table 13, after determining the average importance weight of the agility factors' in project-oriented organizations, for the agility factors that they are members of clusters, the weighted mean of each factor is calculated to obtain the importance weight of cluster. e cluster with the highest weight is placed at the top of the clusters' importance ( Table 14).
As observed in this table, clusters one, two, and three are ranked in the first to third as to their importance, respectively.

Conclusion
To manage and execute a project, in project-oriented organizations, concentrating on the required infrastructures and providing the project management critical success factors, together in addition of considering the importance of environmental resources and social effects of the project and also the profitability and economic aspect which puts the organization in line with appropriate development, as to form a successful project management at macro and microlevels is of essence. By doing so, a big step is taken towards accountability and customer satisfaction due to project implementation, by considering sustainability indices. erefore, a framework is introduced for clustering and analysis of big projects based on agility factors in project-oriented organizations with a sustainability approach, by applying quality functionality development tool. e proposed framework has been implemented and solved in Isfahan Metropolitan Municipality. For this purpose, in phase one, first, the project management critical success factors and, next, the agility factors and in project-oriented organizations and sustainability factors are identified. In phase two, the importance of the project management critical success factors and, next, agility factors in project-oriented organizations are measured from the perspective of large project managers in Isfahan Municipality and university experts. In phase three, the weights of agility factors in project-oriented organizations are calculated based on the weighted factors of sustainability according to the critical success factors in the large projects by applying quality function deployment. In phase four, the agility factors in project-oriented organizations are clustered based on the previously obtained weights. Next to guiding project managers to focus on the major success factors in project management and providing sustainability factors as to the big projects' and activities' impact on the field of environmental resources, social resources, and economic aspects, through focusing on agility factors, they can obtain the desired customer satisfaction level, timely delivery, and desired quality as the major concerns. As observed in Table 14, the first cluster, which includes project communication management, organizational culture, and contract management, is the most important at (0.0987) weight rate. Because these weights are based on sustainability and project management critical success factors, focusing on the important cluster is highly contributive in organizations' success in project management next to the principles of sustainable development and establishing the principles of agility.

Research Constraints
e measures taken in this study, despite the accuracy of the presented framework and application of the applied factors, can be improved by removing any of the constraints therein. Depending on the subject organization, the projects and conditions, addition, elimination, and replacing the applied factors can be contributive in closer insight therein. e findings are implemented on Isfahan Municipality's big projects. To be focused on the paramount cluster helps the organization to be successful in project management in line with setting the principles of the sustainable development and by stablising the principles of the organizational agility in project-oriented organizations.

Suggestions for Future Studies
Assessing the sensitivity analysis of indices and the effect on the clusters' ordering can lead to different and accurate results in the performance of the organization. Moreover, evaluating the performance of projects through the evaluation and performance analysis methods, subject to each approach in addition to the presence of combined approaches, can be effective in improving efficiency. e effect of each one of these approaches on project cost, time, and quality must be considered in project performance assessment.
