Estimates of project planning parameters are established and maintained.
Project planning parameters include all information needed by the project to perform necessary planning, organizing, staffing, directing, coordinating, reporting, and budgeting.
The acquirer develops estimates for project work based on the acquisition strategy, including high-level estimates for the work to be done by suppliers. Initial estimates can be revised based on supplier estimates in response to the
solicitation package.
Estimates of planning parameters should have a sound basis to instill confidence that plans based on these estimates are capable of supporting project objectives.
Manage corrective actions to closure.
Example Work Products
1. Corrective action results
Example Supplier Deliverables
1. Corrective action results for supplier issues
Subpractices
1. Monitor corrective actions for their completion.
2. Analyze results of corrective actions to determine the effectiveness of the corrective actions.
3. Determine and document appropriate actions to correct deviations from planned results from performing corrective actions.
Lessons learned as a result of taking corrective action can be inputs to planning and risk management processes.
Factors to consider when estimating these parameters include the following:
· The acquisition strategy
· Project requirements, including product requirements, requirements imposed by the organization, requirements imposed by the customer, and other requirements that affect the project
· The scope of the project
· Identified tasks and work products
· The technical approach
· The selected project lifecycle model (e.g., waterfall, incremental, spiral)
· Attributes of work products and tasks (e.g., size, complexity)
· The schedule
· Models or historical data used for converting attributes of work products and tasks into labor hours and costs
· The methodology (e.g., models, data, algorithms) used to determine needed material, skills, labor hours, and cost
The acquisition strategy is a key factor when estimating the project.
Documentation of the estimating rationale and supporting data is needed for stakeholder review and commitment to the plan and for maintenance of the plan as the project progresses.
