What is the MoSCoW method exactly

Essowe Abalo


It should be known that it was Dai Clegg who, in 1994, created the MoSCoW method, also known as the Moscow analysis approach or Moscow prioritisation, in order to help his team members prioritise tasks within the framework of the agile project approach DSDM: "Dynamic Systems Development Method."
What is MoSCoW Analysis Technique.

The MoSCoW method is a project management technique used to prioritse the requirements of a project based on their importance.

The acronym represents the four categories of requirements:

Must Have (M - absolutely necessary)
These are requirements essential to the success of the project. Without them, the project cannot be considered complete.

For example, if you're building a car, the engine would be a "Must Have" requirement because without it, the car cannot operate.

Should Have (S - should have)
These requirements are important but not vital. The project can function without them, but their absence can reduce its quality or functionality.

For example, a car should have an air conditioning system for passenger comfort, but it can still run without it.

Could Have (C - could have)
These requirements are desirable but not necessary. They could be included if time and resources allow.

For example, a sunroof on a car would be a "Could Have" requirement. It can enhance the driving comfort, but the car can function perfectly fine without it.

Won’t Have (W - will not be included)
These requirements are recognized but will not be considered in the current project.

For example, although installing a satellite navigation system in a car may be beneficial, it may be decided that this feature will not be included in the current model.

A Requirement Matrix Model

The MoSCoW matrix provides a clear structure for classifying a project's requirements. This matrix, when used correctly, allows for optimal resource distribution and helps determine which tasks to accomplish first.

The MoSCoW technique in 4 steps
Step 1: Identify all the project requirements. This step is essential as it defines the whole workload.

Step 2: Assign each requirement to a MoSCoW category based on its relative importance to the project's success.

Step 3: Develop an action plan based on requirement priorities. Always start with the "Must Haves," then move on to the "Should Haves," and so on.

Step 4: Regularly review the matrix to ensure that it still reflects the project's priorities.

Five good reasons to use the MoSCoW method

  1. It provides a clear structure for task prioritization.
  2. It facilitates communication with stakeholders about project priorities.
  3. It helps avoid burnout by focusing on the essentials.
  4. It allows potential problems to be anticipated by identifying non-essential requirements.
  5. It improves project efficiency and productivity.

Three pitfalls to avoid

  1. Avoid classifying all requirements as "Must Haves". This could distort priorities and render the method useless.
  2. Avoid neglecting the "Won’t Haves". It's important to clearly communicate what will not be included in the project.
  3. Avoid letting the matrix stagnate. Priorities can change, so the matrix must be reviewed regularly.

Two Alternatives to the MoSCoW Method

  1. The Pareto chart is another effective method for prioritising requirements based on the 80/20 principle.
  2. The Kano method can be used to understand customer needs and determine which features add the most value.

In Conclusion

The MoSCoW method is a valuable tool for managing a project's requirements. It can improve efficiency, communication, and stakeholder satisfaction. However, like any tool, it must be used correctly to reap maximum benefits.
