Why is it important to list all the tasks involved in a project in completion order?

Not using a RACI matrix in project management can lead to confusion about roles and responsibilities, lack of accountability, and potential conflicts among team members. It can also result in tasks being overlooked or duplicated, and can make it difficult to identify who should be consulted or informed about each task. This can ultimately lead to inefficiencies, delays, and potential failures in the project.

The roles defined in a RACI matrix are: Responsible, Accountable, Consulted, and Informed. 'Responsible' is the person who does the work to complete the task. 'Accountable' is the person who is ultimately answerable for the correct and thorough completion of the task. 'Consulted' are the people who provide input into the task and 'Informed' are those who need to be kept up-to-date on progress towards task completion.

The RACI matrix helps in stakeholder management by clearly defining the roles and responsibilities of each stakeholder in a project. It ensures that every task has a responsible stakeholder and that no task has more than one stakeholder accountable. This helps in avoiding confusion and conflicts, and ensures smooth execution of the project.
