Related with business analysis, especially in stakeholder analysis, we need to learn some knowledge and technique. Here are some techniques taken from Wikipedia and IIBA.
A responsibility assignment matrix (RAM), also known as RACI matrix or ARCI matrix or linear responsibility chart (LRC), describes the participation by various roles in completing tasks or deliverables for a project or business process. It is especially useful in clarifying roles and responsibilities in cross-functional / departmental projects and processes. RACI and ARCI are acronyms derived from the four key responsibilities most typically used: Responsible, Accountable, Consulted, and Informed.
Those who do the work to achieve the task. There is at least one role with a participation type of responsible, although others can be delegated to assist in the work required.
#Accountable (also approver or final approving authority)
The one ultimately answerable for the correct and thorough completion of the deliverable or task, and the one who delegates the work to those responsible. In other words, an accountable must sign off )approve) on work that responsible provides. There must be only one accountable specified for each task or deliverable.
#Consulted (sometimes counsel)
Those whose opinions are sought, typically SME (Subject Matter Experts) and with whom there is two way communication.
Those who are kept up-to-date on progress, often only on completion of the task or deliverable; and with whom there is just one-way communication.
Very often the role that is accountable for a task or deliverable may also be responsible for completing it. Outside this exception, it is generally recommended that each role in the project or process for each task receive, at most, just one of the participation types. Where more than one participation type is shown, this generally implies that participation has not yet been fully resolved, which can impede the value of t his technique in clarifying the participation of each role on each task.
The RACI matrix describes the roles of those involved in business analysis activities. It describes stakeholders as having one or more of the following responsibilities for a given task or deliverable :
#R : Responsible does the work.
#A : Accountable is the decision maker. (Only One)
#C : Consulted must be consulted prior to the work and gives input.
#I : Informed means that they must be notified of the outcome.
