The project kick-off meetings are extremely important and all the information about the project should be put on the table, specially the roles and responsibilities of each team member. This enables project managers to delegate efficiently.
So, irrespective of the project size, job descriptions should be clearly defined. One way to define each team members role is to define a responsibility assignment matrix, also known as RACI matrix. It provides a detailed description of who is responsible, who is accountable, who should be consulted and who should be informed. Thus, ensuring proper task execution and project success.
