SG 1   Establish Estimates 

        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 provide 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 life-cycle model (e.g., waterfall, incremental, spiral, etc.)

       • 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 (models, data, algorithms) used to determine needed material, skills, labor hours, and cost

        Documenting 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 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 life

   cycle. Project planning should ensure that all plans affecting  the project are consistent with the overall project plan.

    SG 3   Obtain Commitment to the Plan

         To be effective, plans require commitment by those responsible for implementing and supporting the plan.

     GG 2    Institutionalize a Managed Process
