There has been a substantial shift in recent years towards more modern and flexible project management approaches, such as Agile PM delivery and leadership. The increasing complexity of projects, as well as the need for speedier, more flexible, and adaptable project management approaches to keep up with rapidly changing business environments are driving this change.
The key feature of the essay includes the critical evaluation of the strategic rationale stating the results of modern, responsive PM methodologies. The study aims to reflect the Agile PM delivery with leadership to organize, plan, and monitoring 2023 PM and for future prospects.
Agile project management is a method of project management that stresses teamwork, iterative development, and customer input (Heagney, 2016). It entails breaking projects down into smaller, more manageable components known as sprints and continuously adjusting the project plan depending on feedback from stakeholders. This method enables teams to adjust swiftly to changing requirements and prioritize the most important work, perhaps resulting in faster delivery times and more customer satisfaction.
Another reason Agile PM is gaining popularity is that it fits in with the trend towards more flexibility and remote work arrangements. Traditional project management approaches, which rely primarily on face-to-face communication and centralized control, are becoming less effective as remote work and distributed teams become more prevalent. Agile project management, on the other hand, is intended to function in remote situations and can assist teams in remaining connected and on track even when working from different places.
Overall, the strategic reason why Agile PM and other current project management techniques are being preferred in 2023 as well as thereafter is that those who provide a more flexible, adaptive, and cooperative approach to project management that is best suited to today's complex and rapidly changing business environments (Svejvig and Andersen, 2015). As the corporate landscape evolves, Agile PM and other comparable approaches are likely to remain at the forefront of project management.
Literature review
Traditional and modern project management methodology theories
Over time, project management approaches have evolved to address the problems of delivering effective projects. Waterfall and Prince2 are two traditional project management approaches that have been used for decades and are still widely utilized today. All the same, there has been a substantial shift in recent years towards more current and responsive techniques, such as Agile PM and Lean (Edition, 2018). The fundamental difficulties and contrasts between classic and modern project management approaches will be discussed in this literature study, with a focus on Waterfall, Prince2, Agile PM and Lean.
The Waterfall model, assumes that each step of the project must be finished before moving on to the next. The Waterfall approach comprises five phases:
Requirement gathering,
Design,
Implementation,
Testing and,
Maintenance.
This method is appropriate for projects with well-defined criteria and a clear knowledge of the end outcome (Richardson and Jackson, 2018). Waterfall provides a clear and disciplined path for project completion by outlining the complete project plan in advance.
Waterfall, on the other hand, can be rigid and difficult to adjust to changing requirements or unexpected obstacles. Because each step must be finished before going on to the next, making modifications mid-project might be challenging. This can lead to project delays, cost overruns, and, eventually, project failure (AlManei et.al. 2018).
Another major issue with Waterfall is that it assumes that all requirements are known at the beginning of the project, which is often not the case (Hudson and Day, 2019). In reality, requirements can change or evolve over the course of the project as stakeholders gain a better understanding of the project goals and requirements. This can lead to miscommunication and misunderstanding, which can ultimately result in project failure.
Despite its drawbacks, Waterfall is still frequently employed today, particularly in industries where the end result is well-defined and the project timeframe is predictable, such as building and manufacturing. However, in areas such as software development and information technology, where requirements are more likely to alter and evolve over the course of a project, more current and responsive approaches such as Agile PM and Lean have grown in popularity.
Prince2, another conventional project management technique, is widely utilized in the United Kingdom and other areas of the world. Prince2 is a process-based approach to project management that provides a framework. It is founded on the idea of breaking down projects into manageable stages, each with its own set of goals and deliverables. Prince2 is beneficial for large and complicated projects with various stakeholders since it provides a consistent language and framework for all parties involved (Spalek, 2016). However, Prince2 can be bureaucratic and process-heavy, slowing down the project and making it difficult to adjust to changing requirements.
So far, some businesses may find Prince2's process-heavy approach to be a disadvantage. The concentration on documentation and governance can hinder project progress and make being flexible and responsive to changing conditions challenging. Furthermore, some opponents claim that Prince2 can be excessively focused on process and not enough on relationships and individuals, both of which are necessary for successful project delivery.
Overall, Prince2 can be a valuable methodology for managing complicated projects with various stakeholders, but it is critical to analyze the potential negatives and measure them against the projects and organization's specific demands (Pace, 2019).
Agile project management (APM), is a more current project management style based on the Agile Manifesto, which stresses persons and interactions, working software, client collaboration and responsiveness to change. Agile project management is intended to be adaptable, flexible, and responsive to changing requirements. It entails breaking projects down into smaller, more manageable components known as sprints and continuously adjusting the project plan depending on feedback from stakeholders. Agile project management enables teams to adjust quickly to changing requirements and prioritize the most important tasks, resulting in faster delivery timelines and more customer satisfaction.
Lean is a method of project management that was developed in the manufacturing industry but has now been modified for use in other industries, particularly software development. Lean is built on the notion of decreasing waste while increasing customer value (Andrei et.al. 2019). It entails constantly improving processes and minimizing waste in order to deliver projects more quickly and efficiently. Because it focuses on producing value fast and effectively, lean is excellent for initiatives with limited resources and timeframes.
Lean is a highly collaborative methodology that values collaboration and communication. Lean strives to establish a culture of continuous improvement and innovation by including all stakeholders in the project and encouraging open communication (Chari and Agrawal, 2018). This can assist teams in promptly identifying and addressing problems, resulting in better project outcomes.
One of the primary advantages of Lean is that it fosters experimentation and repetition, which can help identify resolution of difficulties early in the project lifecycle. This can lower the likelihood of project failure and raise the likelihood of a successful outcome.
One possible disadvantage of Lean is that it can be difficult to apply in firms accustomed to more traditional project management approaches (Shastri, et.al. 2021). A considerable transformation in thinking and culture is required, as well as a readiness to welcome change and innovation.
One of the primary advantages of Lean is that it fosters experimentation and repetition, which can help identify resolution of difficulties early in the project lifecycle. This can lower the likelihood of project failure and raise the likelihood of a successful outcome (Shou et.al. 2016).
One possible disadvantage of Lean is that it can be difficult to apply in firms accustomed to more traditional project management approaches (Bianchi et.al 2021). A considerable transformation in thinking and culture is required, as well as a readiness to welcome change and innovation.
Here are some examples of each project management methodology:
Waterfall: The Waterfall methodology can be used to manage the development of a new product, such as a car or a Smartphone. Each stage of the development process, such as design, production, and testing is completed before moving on to the next stage under this strategy. Boeing is an example of a corporation that has implemented the Waterfall methodology in their product development process for decades (Stoica et.al. 2016). The aircraft development process at the corporation is sequential, with each stage completed before going on to the next stage.
Prince2: The Prince2 methodology can be used to manage the development of a new building, such as a hospital or a school. This technique entails breaking the project down into manageable stages, with clear goals and deliverables, providing a standard framework and vocabulary for all project stakeholders (Ansah et.al. 2016). The Olympic Games in London in 2012 are an example of a project handled using the Prince2 technique. The project had several stakeholders and a tight deadline, therefore Prince2 was an appropriate framework for project management.
Agile PM: The Agile PM technique can be used to manage the development of a new software website or application. Working in short, multiple repetitions to produce small, progressive improvements to the product while continuously gathering input and adjusting to changing requirements is the goal of this method (Cullen and Parker, 2015). Spotify is one organization that has effectively implemented the Agile Project Management methodology in their software development process. The company works in short, iterative cycles to offer tiny, incremental enhancements to its product while collecting feedback and responding to changing needs.
Lean: The Lean methodology can be used to manage the launch of an innovative business process, such as a supply chain or production line. This method entails finding and removing waste in order to provide greater value to customers while continuously improving operations and lowering expenses (Martínez León, 2019). Toyota is a corporation that has effectively used the Lean technique in its manufacturing processes. The Toyota Production System of the organization focuses on decreasing waste and increasing efficiency in order to provide value to clients more promptly and efficiently.
Empirical review on different methodology to establish the critical evaluation to disadvantages of the methodologies
Traditional project management approaches such as Waterfall and Prince2 have been criticized in recent years for being rigid and bureaucratic, giving rise to the adoption of more modern and responsive methodologies such as Agile PM and Lean (Shou et.al. 2021). While these modern approaches have advantages, it is vital to critically analyze them in order to grasp their limitations and drawbacks. This empirical evaluation will look at each methodology in turn and assess its advantages and disadvantages.
Waterfall technique is a linear strategy that assumes all project needs which are known at the start. This can be a significant drawback because it does not allow for modifications to requirements or unexpected difficulties. Furthermore, it can result in a lack of stakeholder involvement because stakeholders are only involved in the requirements gathering stage and are not consulted again until the project is completed. Furthermore, because each stage of the project must be finished before moving on to the next, the Waterfall process can be slow and inefficient. This might cause delays and make it difficult to complete projects on time and on budget.
Waterfall, despite being a well-established and widely used methodology, has several notable disadvantages. Firstly, the sequential approach of Waterfall can be inflexible and can make it challenging to incorporate changes or feedback from stakeholders. This is because the requirements for the project are defined upfront, and each stage of the project must be completed before moving on to the next stage. Any changes to the requirements or scope of the project can be difficult and costly to implement, especially if they are identified late in the project lifecycle.
Second, Waterfall can be time-consuming because each stage of the project must be finished before moving on to the next. This might result in lengthy lead times, which can be problematic in businesses where time to market is crucial. Furthermore, Waterfall does not prioritize the delivery of value to the customer, which can result in projects that are delivered late, over budget, or do not fulfill the needs of the customer.
Finally, Waterfall is dangerous since it is based on assumptions about project requirements that may or may not be valid. This might result in serious project failures if the assumptions are inaccurate or if needs change over the project lifespan. In rare situations, this can lead to the project being cancelled.
The Prince2 methodology is a procedure approach that provides a foundation for project management. It can, however, be bureaucratic and process-heavy, slowing down the project and making it difficult to adjust to changing requirements. Furthermore, the emphasis on documentation and control may result in a lack of flexibility, as the project plan may not allow for changes in needs or unexpected obstacles. Furthermore, Prince2 might be viewed as a restrictive methodology that inhibits originality and innovation.
While Prince2 offers a complete structure for handling large and complicated projects, it does have several significant drawbacks. For starters, Prince2's process-heavy nature can be cumbersome and bureaucratic, particularly for smaller projects that do not require such a level of detail. As a result, project managers may spend more time on administrative chores than on project management. Furthermore, Prince2's rigidity can make it difficult to adjust to changing situations or requirements. This is due to the methodology's requirement that the project plan and objectives be set at the start of the project and followed throughout its duration. This might lead to a lack of flexibility and make incorporating comments or modifications from stakeholders difficult.
Another drawback of Prince2 is that it might be overly focused upon process and documentation at the cost of creativity and innovation. Following established procedures and guidelines, which can inhibit innovation and creativity, is emphasized in the methodology. Because the rigid framework may make project teams feel constrained, they may be hesitant to submit new ideas or approaches. Finally, Prince2 can be too complex, requiring the management of a huge number of documents, templates and processes. This level of intricacy can be difficult for project managers and team members, particularly those unfamiliar with the technique.
Agile project management approaches are frequently favored over classic project management methodologies because of their ability to adjust fast to changing needs, client input and market conditions. This technique, however, comes with its own set of difficulties. One of the most common accusations leveled about Agile PM is a lack of documentation and planning (ŽURGA, 2018). Agile project management emphasizes face-to-face communication and working technology above documentation, which can make tracking progress and ensuring project completion challenging. This can be especially difficult for larger and more sophisticated projects that necessitate extensive paperwork and preparation. In some circumstances, Agile teams may need to augment their approach with more conventional project administration tools to ensure project management and progress tracking.
Another issue with Agile PM is the possibility of scope creep. Agile project management is predicated on the notion of delivering value in short cycles, however this can make maintaining a clear focus on project goals and objectives difficult. It might be difficult to keep within the project's original scope as stakeholders provide comments and new ideas emerge during development. This might result in delays, cost overruns, and ultimately, a project that does not satisfy the customer's needs.
Furthermore, Agile PM necessitates a high degree of teamwork and communication among team members. This can be difficult if team members operate remotely or in various time zones. Agile PM requires effective communication, and team members must be willing to collaborate to address difficulties and make choices swiftly. This can be especially difficult for distributed teams who must depend on technology to enable communication and collaboration.
Finally, Agile PM might be challenging to deploy in businesses accustomed to more traditional project management approaches. Agile project management necessitates a distinct attitude and culture, which can be difficult to build in businesses accustomed to centralized decision and control. This may necessitate a large investment in training and organizational change to ensure that the organization can fully embrace Agile PM and reap its benefits.
Lean methodology focuses on reducing waste and increasing value for the client. It can, however, be difficult to put into effect because identifying and removing waste is a complicated and laborious process. Therefore, Lean might be viewed as a methodology that is only suitable to particular industries and may not be appropriate to all projects. Furthermore, Lean involves a high level of communication and cooperation, which can be difficult if team members are unfamiliar with working together.
While each methodology offers advantages, it is vital to critically assess them in order to grasp their limitations and drawbacks. Waterfall and Prince2 can be rigid and bureaucratic, whereas Agile PM and Lean can be difficult to put into reality. As a result, when adopting a project management technique, project managers should carefully assess the needs of their project and stakeholders. Using parts of several techniques to develop a customized strategy that matches the specific objectives of the project may be beneficial.
Comparison of Agile PM and Waterfall
Agile PM and Waterfall are two popular project management methodologies that have distinct operating characteristics. Waterfall is a traditional approach to project management that follows a sequential process, whereas Agile PM is an iterative and incremental approach that emphasizes collaboration, flexibility, and customer value.
Here are some key differences between Agile PM and Waterfall:
Approach to project planning: In Waterfall, planning is done upfront, and the project team follows a structured process to create a detailed project plan. Once the plan is in place, work proceeds sequentially through each stage of the project (Van Casteren, 2017). In Agile PM, planning is an ongoing and iterative process that is done in short time frames or sprints. Teams work collaboratively to plan and prioritize work based on customer feedback and changing requirements.
Approach to change management: In Waterfall, change is difficult to accommodate once the project plan is in place. If changes are required, they can be expensive and time-consuming. In Agile PM, change is expected and welcomed, and teams are empowered to make changes to the project scope or requirements based on feedback from stakeholders.
Approach to risk management: In Waterfall, risk management is a formal process that is managed through a risk register, and risk mitigation is the responsibility of a dedicated risk manager. In Agile PM, risk management is an ongoing process that is integrated into the project lifecycle. Teams identify and mitigate risks as they arise, and risk management is seen as a collective responsibility.
Approach to project delivery: In Waterfall, project teams work sequentially through each stage of the project, and the focus is on delivering a fully complete product or project at the end (Lawal, and Ogbu, 2021). In Agile PM, project teams work collaboratively to deliver working software or products in short time frames. Teams are self-organizing and cross-functional, and the focus is on delivering value to the customer.
While Agile PM and Waterfall share some similarities in terms of project management principles and practices, they have distinct operating characteristics that make them better suited for different types of projects and organizations. Waterfall is best suited for projects that have well-defined requirements and deliverables, whereas Agile PM is better suited for projects that require flexibility, innovation, and collaboration.
