In order to achieve goals and planned results within a defined schedule and a budget, a manager uses a project. Regardless of which field or which trade, there are assortments of methodologies to help managers at every stage of a project from the initiation to implementation to the closure. In this tutorial, we will try to discuss the most commonly used project management methodologies.
A methodology is a model, which project managers employ for the design, planning, implementation and achievement of their project objectives. There are different project management methodologies to benefit different projects.
For example, there is a specific methodology, which NASA uses to build a space station while the Navy employs a different methodology to build submarines. Hence, there are different project management methodologies that cater to the needs of different projects spanned across different business domains.
Following are the most frequently used project management methodologies in the project management practice:
In this methodology, the project scope is a variable. Additionally, the time and the cost are constants for the project. Therefore, during the project execution, the project scope is adjusted in order to get the maximum business value from the project.
Agile software development methodology is for a project that needs extreme agility in requirements. The key features of agile are its short-termed delivery cycles (sprints), agile requirements, dynamic team culture, less restrictive project control and emphasis on real-time communication.
In crystal method, the project processes are given a low priority. Instead of the processes, this method focuses more on team communication, team member skills, people and interaction. Crystal methods come under agile category.
This is the successor of Rapid Application Development (RAD) methodology. This is also a subset of agile software development methodology and boasts about the training and documents support this methodology has. This method emphasizes more on the active user involvement during the project life cycle.
Lowering the cost of requirement changes is the main objective of extreme programming. XP emphasizes on fine scale feedback, continuous process, shared understanding and programmer welfare. In XP, there is no detailed requirements specification or software architecture built.
This methodology is more focused on simple and well-defined processes, short iterative and feature driven delivery cycles. All the planning and execution in this project type take place based on the features.
This methodology is a collection of best practices in project management. ITIL covers a broad aspect of project management which starts from the organizational management level.
Involving the client from the early stages with the project tasks is emphasized by this methodology. The project team and the client hold JAD sessions collaboratively in order to get the contribution from the client. These JAD sessions take place during the entire project life cycle.
Lean development focuses on developing change-tolerance software. In this method, satisfying the customer comes as the highest priority. The team is motivated to provide the highest value for the money paid by the customer.
PRINCE2 takes a process-based approach to project management. This methodology is based on eight high-level processes.
This methodology focuses on developing products faster with higher quality. When it comes to gathering requirements, it uses the workshop method. Prototyping is used for getting clear requirements and re-use the software components to accelerate the development timelines.
In this method, all types of internal communications are considered informal.
RUP tries to capture all the positive aspects of modern software development methodologies and offer them in one package. This is one of the first project management methodologies that suggested an iterative approach to software development.
This is an agile methodology. The main goal of this methodology is to improve team productivity dramatically by removing every possible burden. Scrum projects are managed by a Scrum master.
Spiral methodology is the extended waterfall model with prototyping. This method is used instead of using the waterfall model for large projects.
This is a conceptual model used in software development projects. In this method, there is a possibility of combining two or more project management methodologies for the best outcome. SDLC also heavily emphasizes on the use of documentation and has strict guidelines on it.
This is the legacy model for software development projects. This methodology has been in practice for decades before the new methodologies were introduced. In this model, development lifecycle has fixed phases and linear timelines. This model is not capable of addressing the challenges in the modern software development domain.
Selecting the most suitable project management methodology could be a tricky task. When it comes to selecting an appropriate one, there are a few dozens of factors you should consider. Each project management methodology carries its own strengths and weaknesses.
Therefore, there is no good or bad methodology and what you should follow is the most suitable one for your project management requirements.
