Software life cycle planning covers the software aspects of a project from inception through retirement. The software life cycle planning is an organizing process that considers the software as a whole and provides the planning activities required to ensure a coordinated, well-engineered process for defining and implementing project activities. These processes, plans, and activities are coordinated within the project. At project conception, software needs for the project are analyzed, including acquisition, supply, development, operation, maintenance, retirement, decommissioning, and supporting activities and processes. The software effort is scoped, the development processes defined, measurements defined, and activities are documented in software planning documents.
1.1 Inputs
Note
List of some of the inputs from other activities that are necessary for the activity to begin.
Documents and orders that initiate the Planning Activity
High level requirements that define the scope of the software product
Time and budget constraints that further define the scope of the project
1.2 Predecessor Activities
Note
List of some of the other activities that must be started (not necessarily completed) this activity to begin.
The predecessor activities include planning, architecture and design activities from other projects and systems where the concept for the software product is defined. Examples include:
New, or changed, hardware system that requires new software to monitor or control it.
1.3 Outputs
Note
List of some of the outputs or work products of the activity. These are typically used as inputs by the downstream activity. In some cases there is a supporting SWE associated with the work product.
Outputs from Planning include a variety of documents, plans, and other work products that are used by downstream activities
Links to Activities which might be started or supported by this activity.

1.5 Repetition
Note
Describe what conditions determine if the activity needs to be repeated.
How much of the activity needs to be repeated
Frequency of repetition
Life Cycle Planning is done in the early stages of a Software Project. Other work may be started before the planning is actually completed.
During the life of the project there may be multiple times when significant changes to things like requirements, budget, schedule, technology, which make re-planning necessary. Re-planning is covers the same areas of the original planning to make sure that all changes are accounted for in the new plans. Re-planning is done as often as necessary to keep the project under control.
1.6 Center Resources From SPAN
Note
Add links to SPAN activity pages that are appropriate for this activity. Use links from the Activity section of the front page. SPAN
Several Centers Process Asset Libraries have materials related to this activity. Related Processes, templates, and other resources may be found in the following Activities in SPAN (available to NASA only).
This tab contains the links to pages in the SWEHB that are at the heart of the activity.
Life Cycle Planning is a large activity that impacts the whole of the project. The SWEs listed below are included in the NPR 7150.2 under 3.1 Software Life Cycle Planning.
Determinations are made regarding whether the software should be developed using related, existing software, secured by a separate acquisition from another supplier, or built from scratch. In some cases it may be a combination of all these approaches.
Project plans are developed to account for all aspects of the development of the software.
Plans for tracking the progress of the development project are put into place for use in the Monitor and Control activity.
Acceptance Criteria are reviewed and made a part of the plan. These will be used together with Requirements to ensure that the right software is developed and delivered.
The processes to be used in the development effort are selected and coordinated with the Requirement Mapping and Tailoring activity.
Milestones are determined and planned into the project. These are coordinated in the Software Scheduling activity.
Access to developed components is planned for and coordinated with the Configuration Management activity among others.
