The number of systems and subsystems that integrate the project, the different methodological and philosophical assumptions across these systems, the cross-organizational and schedule interdependencies between activities, the upgrading and retrofitting works, and the sheer size and entanglement in the project are all key factors influencing complexity. Projects that, although confined to a limited time-frame, still can achieve their objectives(ii)Fast-Competitive Projects. It is needed across all types of applications, platforms, operating system, and devices. The tasks to simplify the software development services complexity is even more daunting tasks in the landscape of developer and API documentation. Well at that point, you’re now well into the “complex code” territory. Perceived complexity is widely acknowledged to be an important factor affecting the software development process . Projects and programs are not all the same. Fine, “Measurement of complexity in construction projects,” in, P. Bennett and S. Cropper, “Uncertainty and conflict: combining conflict analysis and strategic choice,”, D. Baccarini, “The concept of project complexity—a review,”, K. Remington, R. Zolin, and R. Turner, “A model of project complexity: distinguishing dimensions of complexity from severity,” in, H. Parsons-Hann and K. Liu, “Measuring requirements complexity to increase the probability of project success,” in, L.-A. According to Parsons-Hann and Liu , it is evident that complexity contributes to project failure in organizations; what is not clear is to what degree this statement holds true. Overall and task complexity can be managed by a functional organization with decentralized decision-making and social complexity by trust and commitment, whereas cultural complexity by sense-making processes. Without individuals and organizations pouring money into the software services, that they give freely to the community, much of what we build today cannot be possible without an order of magnitude more cost and effort.  suggest to differentiate between dimensions, characteristics, or sources of complexity, and severity factors, those factors that increase or decrease the severity of complexity. The S32K1 family, released in 2017, marked an important turning point in addressing software’s central role in automotive development. In project contexts, there is a lack of consensus on what complexity really is [12–20]. As the number of entities increases, the number of interactio… L. M. Corbett, J. Brockelsby, and C. Campbell-Hunt, R. Dewar and J. Hage, “Size, technology, complexity, and structural differentiation: toward a theoretical synthesis,”. It explains why there is a need for a variety of technologies and a given level specialization in each of them. Then, the different types of project complexity and the main project complexity models are presented. Tatikonda and Rosenthal  view complexity as consisting of interdependencies among the product and process technologies and novelty and difficulty of goals. (i)Scope 1: Assembly. Furthermore, uncertainty has been broken down into four levels of technological uncertainty (low-, medium-, high-, and super high-technology projects). Pich et al. Pich et al. Project complexity can also be interpreted and operationalized in terms of differentiation (number of elements in a project) and interdependencies and connectivity (degree of interrelatedness between these elements), which are managed by integration, that is, by coordination, communication, and control [1, 8, 26–29]. There does not even seem to be a single definition of project complexity that can capture the whole concept [11, 20–24]. Since there has been a lack of consensus and difficulty in defining complexity, some authors have focused on identifying the factors that contribute or increase project complexity. Cultural complexity compresses the history, experience, and sense-making processes of different groups that joint the effort in a project. Importance of Human Resource HR in Organization. If the project is politically sensitive and of high visibility, project complexity can considerably be increased.  explore the evolution of management styles associated with the organizational complicacy of simple and complex projects. A large number of studies have found that size is related to structural differentiation, but the relationship between size and complexity is less clear [37, 40, 42] . It may also involve seeing beyond our product for considering the larger journey on which is user’s there- even before they arrived at the products. One’s ability to handle complexity is not static. Identifying the sources and factors that contribute or increase project complexity is paramount for project managers. In this type of projects, since time to market is directly associated with competitiveness, missing the deadline might not be fatal but it could hurt competitive positions(iii)Critical-blitz projects are the most urgent and most time-critical projects in which meeting schedule is critical to success and project delay means project failure. Relationships between project participants, suppliers, overlapping of activities, methods, and techniques are factors that affect project complexity. In addition to the two components of complexity suggested by Baccarini, i.e., the number of elements and the interdependency of these elements, the authors introduce uncertainty and attributes the increasing complexity in projects to two compounding causes, the relationship between product complexity and project complexity and the length of projects. Complexity influences project planning and control; it can hinder the clear identification of goals and objectives, it can affect the selection of an appropriate p… Technical complexity is found in architectural, industrial design, and R&D projects which have design characteristics or technical aspects that are unknown or untried and where complexity arises because of the uncertainty regarding the outcome for many independent design solutions . Critical-blitz projects are the most urgent and most time-critical projects in which meeting schedule is critical to success and project delay means project failure. How to choose the best candidate between two applicants? According to the author, if there are limits to what we can know about our organization, there are limits to what we can achieve in a predetermined and planned way. Therefore, some of the tools are a great platform on which we can build our software systems, but at the end of the day, you are still left to build all the business logic and interfaces in our increasingly complex and demanding system. It encompasses two components, the number of elements (multiplicity) and their dissimilarity (variety). According to a study performed by Beyer and Trice  on several departments of the US governments, size is a more important predictor of complexity while in a similar study from state employment agencies, Blau and Schoenherr  found that division of labor is a more important predictor of complexity. The application security is the most significant overlooked non-functional requirements. Concurrent Engineering breaks down functional and departmental barriers by integrating team members with different discipline backgrounds often known as cross-functional teams . Projects based on existing and well-established technologies, Medium-Technology Projects. The one, usually known as the field of descriptive complexity, considers complexity as an intrinsic property of a system, a vision which invited researchers to try to quantify or measure complexity. Maintaining and managing the sizable test suite is quite complex for any organization. U. Steger, W. Amann, and M. L. Maznevski, R. E. Levitt, J. Thomsen, T. R. Christiansen, J. C. Kunz, Y.

Baccarini  considers technological and organizational complexities as the core components of project complexity. In this case, the role of the project manager is that of a conductor; (ii) type 2 projects are projects with well-defined goals but poorly defined methods. Project complexity is determined in my organization by evaluating project attributes using the seven criteria listed below: 1. Identifying the different concepts associated to project complexity, its main factors and characteristics, the different types of project complexity, and the main project complexity models, can be of great support in assisting the global project management community. Broadly speaking, technology can be defined as the transformation process which converts inputs into outputs using materials, means, techniques, knowledge, and skills [8, 26]. For modernization, the software development lifecycle is very complex, global and overdue. Vidal and F. Marle, “Understanding project complexity: implications on project management,”, S. C.

Williams, “Now, let’s make it really complex (complicated) a systematic review of the complexities of projects,”, L.-A. External influences can either be political or market-related changes, while internal influences come from changes in strategy, in individual behaviour, etc. In this case, the role of the project manager is that of a coach; (iii) type 3 projects are projects planned in life-cycle stages with poorly defined goals but well-defined methods; and (iv) type 4 projects are projects with no defined goals and no defined methods. Payne  takes a perspective which combines difficulty and systems thinking, associating complexity with the multiple interfaces between individual projects, the organization, and the parties concerned. In this carefully chosen example, the volume of work (licking 1,000 stamps and one snip to some part of the brain) and the complexity of that work combine such that each will take the same amount of time. However, to consider size an indication of complexity, the organizational structure of a system should be over a minimum critical size and their elements need to be interrelated . Complicated implies being difficult to understand but with time and effort, ultimately knowable. Long Term Benefits of Software Complexity Analysis. Complex projects require specific project management (PM) competences development. Of course, simplifying complexity involves understanding enough about the domain and the customer's journey to speak at their level and in their terminology but it is more than that.Simplifying complexity involves incorporating the host of techniques which go beyond mere transmission of knowledge in a particular domain. Sommer and Loch  treat complexity and unforeseeable uncertainty as separate constructs. Girmscheid and Brockmann  define project complexity as a set of problems that consists of many parts with a multitude of possible interrelations, most of them being of high consequence in the decision-making process that brings about the final result. Trying to find the most appropriate model for managing a project can be a difficult task. In this type of projects, since time to market is directly associated with competitiveness, missing the deadline might not be fatal but it could hurt competitive positions. Experience suggests that the interrelationships between the project’s components are more complex than is suggested by the traditional work breakdown structure of project network. Vidal and Marle  argued that approximately 70% of the complexity factors of the project are organizational. Experts overconfident in their own solutions, Encourage external and internal stakeholders to challenge expert opinions, Temptation to fall back into habitual, command-and-control model, Applying a command-and-control approach longer than needed, Set up mechanisms to take advantage of the opportunities afforded by a chaotic environment, P. W. G. Morris, “Science, objective knowledge and the theory of project management,”, J. Bennett and B. Traditional project management tools and techniques, based on the assumptions that a set of tasks can be discrete, with well-defined information about time, cost, and resources, and with extensive preplanning and control, are often found inadequate. Williams and Hillson  extend Baccarini’s model by one additional dimension. It is also important to have an accurate, repeatable set of complexity metrics, consistent across the technology layers of the application portfolio to provide benchmarking for continued assessment as changes are implemented to meet business or user needs. Table 2 shows the characteristics of each context, the leader’s job, the danger signals, and the response to these danger signals . The importance of complexity to the project management process is widely acknowledged for several reasons [1–8]: (i) it influences project planning, coordination, and control; (ii) it hinders the clear identification of goals and objectives of major projects; (iii) it can affect the selection of an appropriate project organization form and experience requirements of management personnel; (iv) it can be used as criteria in the selection of a suitable project management arrangement; and (v) it can affect different project outcomes (time, cost, quality, safety, etc.). Complexity can have both a negative and a positive influence on projects. It's not that the people I'm talking to are stupid, they're quite honestly people at the top of their respective (non-tech) fields. According to Pundir et al. In part one, I covered the technical debt side of sustainable software development. 6 Stages of Software Development Process “ As the world became more and more dependent on technology with each passing day, software automatically became an important organ for development. This is very simple. Organizational and interactive management is one of the riskiest parts of a project. H. Singh and A. Singh  argue that it is at the edge of chaos, where linear systems begin to fail and nonlinear systems begin to dominate and where project managers must begin to pay greater attention to the nonlinear and subtle influences in their planning and management styles. Context’s characteristics, leader’s job, danger signals, and response to danger signals. Remington et al. As projects have become more and more complex, there has been an increasing concern about the concept of project complexity and the application of traditional tools and techniques developed for simple projects has been found to be inappropriate for complex projects [1, 8]. To consider it an indication of complexity, the organizational structure of the project should be over a minimum critical size and their elements need to be interrelated. Globalization boots complexity by the erosion of boundaries, higher mobility, heterarchy, and higher dynamics . An event in an interconnected structure can cause totally unknown effects on another entity inside the structure. In order to properly manage complexity, project managers must know how to seize the opportunities emerging from complexity and to know how to avoid or at least diminish the negative effects of complexity . The complex and chaotic domains do not have a clear cause and effect relationship, and decisions must be made based on incomplete data. So complexity is a factor in the number of story points assigned, but only to the extent to which that complexity increases the expected effort. Contractor relationships and ethics, supplier monopolies, overlapping of processes and activities, methodologies, and techniques based on either hard or soft approaches that can affect the degree of definition of project goals and objectives are all factors that can influence project complexity. Finally, the current and the future management approaches to address this topic in the future are proposed. Technology readiness, 5. Projects conceived to create strategic positions, address market opportunities, etc. This trend can be observed in Fig. Complexity and Project Management: A General Overview, Project Management Research Group, Universidad de Cantabria, Santander 39004, Spain, Department of Naval and Industrial Engineering, GEM, Universidade da Coruña, Ferrol 15403, Spain, Escuela Técnica Superior de Náutica, Universidad de Cantabria, Santander 39004, Spain, Low-Technology Projects. Moreover, not all software project is time and material contracts, some of them ar… Though the use of development testing and development testing platform, is more known about the software which are running the organizations and representing your brand. Risk, 6. We are committed to sharing findings related to COVID-19 as quickly as possible. complexity measures continue to appear, and new support for old measures is earnestly sought. Atkinson et al. The demand placed on the software which runs on the business means that automation must be employed when and where it is feasible for meeting time to time market and quality pressure. Projects based on non-yet existing technologies in which, although the project goal is clear, no technology is known to achieve the final product, Scope 1: Assembly. Projects conceived to create strategic positions, address market opportunities, etc. An understanding of project complexity and how it might be managed is of significant importance for project managers because of the differences associated with decision-making and goal attainment that appear to be related to complexity [8, 9]. Directional complexity is often found in change projects where the direction of the project is not understood and when it is clear that something must be done to improve a problematic situation .  defines a complex project as one that demonstrates a number of characteristics to a degree or level of severity that makes it extremely difficult to predict project outcomes, to control or manage the project. This means that the testing is critical, ongoing, measured and managed. Successful software-complexity- measure development must be motivated by a the- ory of programming behavior. Diversity is defined as the plurality of elements. Part of the literature has focused on uncertainty [32, 63]. Copyright © 2018 José R. San Cristóbal et al. Projects that integrate a collection of new but existing technologies(iv)Super High-Technology Projects. A higher number of elements and a higher variety across elements increase complexity. These traditional approaches that utilize a static approach provide project managers with unrealistic estimations ignoring multiple feedback processes and nonlinear relationships of the project. Table 1 shows the main factors that are considered in the literature as drivers of project complexity. Tatikonda and Rosenthal  and Pundir et al. To lead complex projects to success, this complexity must be measured quantitatively and, in our opinion, project management complexity assessment should be based on existing PM standards. If the model is too simple, it is not enough close to reality. According to Vidal and Marle , there are historically two main approaches of complexity. If we compare a developer and a tester, then for a developer the configuration becomes trivial but for the tester it becomes absolutely complex. The negative influence, in terms of difficulty to be understood and controlled, is because of the emergence of new properties that none of the elements of the system owns. Temporal complexity results in projects where due to unexpected legislative changes of rapid changes in technology, there is a high level of uncertainty regarding future constraints that could destabilize the project.
