The following specific goals are associated with this process area:
SG 1 Establish Estimates
Estimates of project planning parameters are established and maintained.
Project planning parameters include all information needed by the project to perform the necessary planning, organizing, staffing, directing,
coordinating, reporting, and budgeting.
Estimates of planning parameters should have a sound basis to instill confidence that any plans based on these
estimates are capable of supporting project objectives.
Factors that are typically considered when estimating these parameters include the following:
-
Project requirements,
including the product requirements, the requirements imposed by the organization, the requirements imposed
by the customer, and other requirements that impact the project
-
Scope of the project
-
Identified tasks and work products
-
Technical approach
-
Selected project lifecycle
model (e.g., waterfall, incremental, or spiral)
-
Attributes of the work products and tasks (e.g.,
size or complexity)
-
Schedule
-
Models or historical data for converting the attributes of the work products and tasks into labor hours and cost
-
Methodology (e.g., models, data, algorithms) used to determine needed
material, skills, labor hours, and cost
Documentation of the estimating rationale and supporting data is needed for stakeholders’ review and commitment
to the plan and for maintenance of the plan as the project progresses.
SG 2 Develop a Project Plan
A project plan is established and maintained as the basis for managing the project.
A project plan is a formal, approved document used to manage and control the execution of the project. It is based on the project requirements and the established estimates.
The project plan should consider all phases of the project lifecycle. Project planning should ensure that
all plans affecting the project are consistent with the overall project plan.
SG 3 Obtain Commitment to the Plan
Commitments to the project plan are established and maintained.
To be effective, plans require commitment by those responsible for implementing and supporting the plan.
