Globalization boots complexity by the erosion of boundaries, higher mobility, heterarchy, and higher dynamics [46]. 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. The context and environment under which the project is undertaken can be an essential feature of complexity. A collection of components in a single unit, performing a well-defined limited function, Scope 2: System. Payne [70] takes a perspective which combines difficulty and systems thinking, associating complexity with the multiple interfaces between individual projects, the organization, and the parties concerned. A value between 8 and 10 is often the upper limit before code analysis tools will start warning you. The developers have deeper and more comprehensive technical skills and also understanding than most technical writers. In software development, effort estimation is the process of predicting the most realistic amount of effort (expressed in terms of person-hours or money) required to develop or maintain software based on incomplete, uncertain and noisy input. It can be done by shaping our documentation around schemes that the user already uses for categorizing each information into segments. How complexity is perceived and interpreted by project managers may result in different types of project complexity. External influences can either be political or market-related changes, while internal influences come from changes in strategy, in individual behaviour, etc. Social complexity describes the number of members communicating and working with each other and the differentiation of their tasks, while cultural complexity encompasses the number of different historical experiences and sense-making processes that confront each other in a project. Tackling cost and complexity of automotive software development. Well at that point, you’re now well into the “complex code” territory. Measuring software complexity on an ongoing basis helps project teams and technology management detect problems early in the development cycle, and identify areas of source code where complexity is high or increasing. Pollack and Remington and Pollack [50, 51] emphasize that a clear distinction on the type of complexity helps in selecting the appropriate model to manage a project. Moreover, not all software project is time and material contracts, some of them ar… Projects that, although confined to a limited time-frame, still can achieve their objectives(ii)Fast-Competitive Projects. Williams and Hillson [55] extend Baccarini’s model by one additional dimension. Programming complexity (or software complexity) is a term that includes many properties of a piece of software, all of which affect internal interactions. The positive influence is due to the apparition of phenomena that could not be predicted due to the sole knowing, even complete, of the behaviour and interactions of the elements of the system. “Highly specific project definitions usually go astray very quickly. In fact, the methods and practices applicable to a project may not be directly transferable to other projects with different institutional, language, and cultural configurations. Girmscheid and Brockmann [34] 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. If the model is too simple, it is not enough close to reality. It also implies constant change and adaptation to changing conditions. In this paper, we give a general overview of how complexity has been investigated by the project management community and propose several ideas to address this topic in the future. As projects have become more and more complex, there has been an increasing concern about the concept of project complexity. Stacey [54], Kahane [56], and Snowden and Boone [57] focus on how complexity, particularly messy or ill-structured problems, might influence leadership style and decision-making in periods of organizational change. The application security is the most significant overlooked non-functional requirements. Manual practices are quite impossible to maintain and extract the right information from a variety of places is time-consuming, chaotic and unreliable.By far, the great gain we have made in software development in the last two decades is open source software (OSS). Shenhar [65] regards complexity and uncertainty as orthogonal to each other. Effort estimates may be used as input to project plans, iteration plans, budgets, investment analyses, pricing processes and bidding rounds. 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 [51]. Over the past few decades, our IT industry has been very successful in reducing the amount of custom code which it takes to write most software. Complexity into three levels of system scope is based on a hierarchy of systems and subsystems (assembly, system, and array) and pace into three levels (regular, fast-competitive, and critical-blitz projects) [58–60]: Diversity is defined as the plurality of elements. 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. The most important lesson to draw from these models is that software development is at least ‘complicated’, probably ‘complex’ and occasionally ‘chaotic’ on the product- or project-level. The major key point for security is prevention. Lifecycle Issues in Software Development Complexities. Task scope or the variety of tasks that need to be accomplished is the most critical dimension of technology. According to Parsons-Hann and Liu [10], it is evident that complexity contributes to project failure in organizations; what is not clear is to what degree this statement holds true. The new complex and dynamic environments require project managers to rethink the traditional definition of a project and the ways to manage it. 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. Why is this? Context’s characteristics, leader’s job, danger signals, and response to danger signals. In this work, the main project compl… Structural complexity stems from large-scale projects which are typically broken down into small tasks and separate contracts. 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. Projects conceived to create strategic positions, address market opportunities, etc. They must be adequately and properly defined both at a strategic and at an operational level. 16,401 Complexity Science jobs available on Indeed.com. Tatikonda and Rosenthal [31] view complexity as consisting of interdependencies among the product and process technologies and novelty and difficulty of goals. So, if your code has a cyclomatic complexity value over 10, you shouldn’t hesitate to try and fix it right away. 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 are related to complexity. 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. [9] suggest to differentiate between dimensions, characteristics, or sources of complexity, and severity factors, those factors that increase or decrease the severity of complexity. Globalization boots complexity by the erosion of boundaries, higher mobility, heterarchy, and higher dynamics. For all practical purposes, a project manager deals with perceived complexity as he cannot understand and deal with the whole reality and complexity of the project. Adding project organizational structure by dividing labor into smaller and more specialized tasks, the way for personnel selection, and the level of pressure on the personnel to achieve project objectives are all factors that can increase project complexity. Trying to find the most appropriate model for managing a project can be a difficult task. Other approaches used to deal with complexity in project management contexts include systems theory to help understand how different aspects affect the project as a system [8, 51, 55]. Adding project organizational structure by dividing labor, the way for personnel selection, and the level of pressure on this personnel to achieve project objectives are factors that increase project complexity. Long Term Benefits of Software Complexity Analysis. The complex and chaotic domains do not have a clear cause and effect relationship, and decisions must be made based on incomplete data. Maintaining and managing the sizable test suite is quite complex for any organization. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. It creates a link or influence of different types between entities in such a way that an event in an interconnected structure can cause totally unknown effects on another entity inside the structure [43]. Williams [64] views the number of elements and their interrelationships as constituents of structural uncertainty which is proposed as an element of complexity. 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. According to Pundir et al. Richardson [35] associates linearity with complicated projects and nonlinearity with complex projects, which implies that nonlinearity makes the relationship between inputs and outputs unpredictable. Typically, engineering and construction projects fall within the category of type 1 projects. One’s ability to handle complexity is not static. Baccarini [8] proposes to define technological complexity in terms of differentiation and interdependencies. The number of project participants and how the information flows between them are a key factor affecting project complexity. Without the development platform, executives and the managers manually seek out the information and the potential risks about the application under development and test which makes it subjective assessment about the status of an application with the organization. The new S32K3 MCUs provides free automotive-grade drivers and over-the-air (OTA) security updates and streamlines safety compliance for ASIL certification. Girmscheid and Brockmann [34] argue that any difference between a complicated project and a complex project has to do with the number of elements as opposed to the relationships between the elements (complex). Pich et al. It expresses uncertainty of meaning in which multiple interpretations are plausible. Perceived complexity is widely acknowledged to be an important factor affecting the software development process . Importance of Human Resource HR in Organization. Early methods from the general management literature include Declerck and Eymery’s [62] method for analysing ill-structured problems and Turner and Cochrane’s goals and methods matrix [53]. It is a challenging component of the software lifecycle and there are many businesses that spend an inordinate amount of precious time and resources for grappling with understanding test suites. Complexity influences project planning and control; it can hinder the clear identification of goals and objectives, it can affect the selection of an appropriate project organization form, or it can even affect project outcomes.

Defect leakage occurs due to a lag between the introduction of a defect and the identification of the defect. There are some common lifecycle issues of software development complexity given below: Of the core continues in the software lifecycle, only QA and the operations rely on and are held accountable to metrics. Ward and Chapman [33] view the number of influencing factors and their interdependencies as constituents of complexity. Technology readiness, 5. In part one, I covered the technical debt side of sustainable software development. Furthermore, uncertainty has been broken down into four levels of technological uncertainty (low-, medium-, high-, and super high-technology projects). When using the U-process developed by Kahane [56], project managers undertake three activities: (i) sensing the current reality of the project; (ii) reflecting about what is going on and what they have to do; and (iii) realizing and acting quickly to bring forth a new reality. and Müller et al. 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. Identifying the sources and factors that contribute or increase project complexity is paramount for project managers. The interrelationships between the components of a project are more complex that is suggested by traditional techniques, which makes them inadequate to the challenges of today’s dynamic project environment. Pich et al. A higher number of elements and a higher variety across elements increase complexity. According to Vidal and Marle [11], there are historically two main approaches of complexity. Organizational and interactive management is one of the riskiest parts of a project. All these works highlight the importance of complexity in project contexts in general and in particular its effects on project goals and objectives, project organization form and arrangement, and in the experience requirements for the management personnel. A large collection of systems functioning together to achieve a common purpose, Regular Projects. This means complexity depends on the knowledge level of the user handling it. It also enables software reuse among multiple applications to reduce the complexity of vehicle software development for Tier 1 suppliers and carmakers. This is very simple.

Successful software-complexity- measure development must be motivated by a the- ory of programming behavior. Projects based on non-yet existing technologies in which, although the project goal is clear, no technology is known to achieve the final product(b)The system scope dimension (complexity) Increase in automation helps to minimize human errors and enables the software teams to focus on more strategic part aspects of the software lifecycles. These traditional approaches that utilize a static approach provide project managers with unrealistic estimations ignoring multiple feedback processes and nonlinear relationships of the project. When measuring complexity, it is important to look holistically at coupling, cohesion, SQL complexity, use of frameworks, and algorithmic complexity. 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. [16] conducted an online survey using the TOE framework (technical, organizational, and environmental) and came to determine the position of the respondents about the nature of the complexity of the organization in engineering projects. [17, 67] support uncertainty as an element of complexity. The developers have deeper and more comprehensive technical skills and also understanding than most technical writers. Or consuming the complete information space just to see how we are adding integrates and harmonizes with the whole. Managing conflicting agendas of various stakeholder management strategies and processes, which is linked to structural complexity, can also amplify the complexity of a project. L. M. Corbett, J. Brockelsby, and C. Campbell-Hunt, R. Dewar and J. Hage, “Size, technology, complexity, and structural differentiation: toward a theoretical synthesis,”. Project complexity has been addressed by researchers from different perspectives and approaches. It also helps in lack of effective automation and struggles with functional requirements. [9] 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. To achieve this objective, more integrated approaches for managing projects in complex environments and new methods of planning, scheduling, executing, and controlling projects must be investigated. 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. Vague enough definitions allow for creativity and selectivity for the people doing the work.” But he seems to suggest some complexity could be reduced by carefully and thoughtfully examining the whole software development process. When problems fundamentally dynamic are treated statically, delays and cost overruns are common. Stacey [54] analysed complexity on two dimensions, the degree of certainty and the level of agreement and, based on these two dimensions, developed the matrix shown in Figure 2 with the following zones: (i) close to agreement, close to certainty: in this zone, we can find simple projects where traditional project management techniques work well and the goal is to identify the right process to maximize efficiency and effectives; (ii) far from agreement, close to certainty: in this case, coalitions, compromise, and negotiation are used to solve this type of situations; (iii) close to agreement, far from certainty: in this case, traditional project management techniques may not work and leadership approaches must be used to solve this type of situations; and (iv) far from agreement far from certainty: this is the zone of anarchy with a high level of uncertainty and where traditional management techniques will not work. Software development project teams are often faced with high levels of complexity, since it is not unusual to build a system which has multiple interfacing components and is measured in millions of lines of code . Flux is affected by external and internal influences. The resulting model is shown in Figure 3 where, as can be seen, project complexity is characterized by two dimensions, structural complexity and uncertainty, each of one having two subdimensions, number and interdependency of elements, and uncertainty in goals and methods, respectively. Authorization basis. For modernization, the software development lifecycle is very complex, global and overdue. BMazurek asks: "I'm stumped by how to explain software development complexity (not theoretical big-O notation, that's easy) to non-developers.When it comes to people who aren't in the code, my explanations fall flat.
