The "Won't have" category is crucial to managing expectations. One mistake is not clearly defining what won't be included in the project, leading to scope creep. This can result in unnecessary work or demand changes from stakeholders that should be avoided to keep the project on track.
While MoSCoW is a structured method, it's essential to remain flexible when necessary. Some project managers might rigidly adhere to the initial prioritization without considering external changes or new insights. Being too rigid can prevent the team from adjusting to evolving needs.
MoSCoW prioritization also needs to account for the team's capacity. A common error is overestimating what the team can handle, leading to burnout or subpar performance. Task allocation should be realistic in terms of team bandwidth and resources.
Another mistake is failing to communicate MoSCoW priorities to the team effectively. If the team is unclear about which tasks are "Must have" or "Should have," they may focus on the wrong objectives. Clear, consistent communication is essential for the technique to succeed.
MoSCoW relies on each team member taking responsibility for specific priorities. A mistake is not assigning clear ownership of tasks, leading to confusion about who is responsible for what. This can delay progress and reduce the accountability necessary for successful project completion.
