1. Introduction

Software Engineering activities are conducted in a predictable sequence. This sequence may be a once through / "waterfall" cycle. Or, it may be an iterative  or evolutionary series of cycles which build toward a final product. Regardless of the model chosen, individual activities in all these cycles are very similar. 

The major activity groupings here give you a quick way to find guidance in the SWEHB to help you satisfy the needs of the development project while also satisfying the requirements of NPR 7150.2. 

The activities associated with Software Engineering are listed in the tabs of this page. Each tab takes you to a list of links to pages where the activity is is explained in more detail. At the lowest level, there is a list of links to specific pages in the SWEHB where details of the activity are explained and more guidance is provided. In some cases, templates or other Process Assets are included to further help you in conducting the activity. 

1.1 Activity Groupings

2. Management

The Management activities associated with Software Engineering are listed as links below. 

Management activities are typically conducted by those in leadership roles. Supervisors, managers and team leads are involved to varying degrees. Some activities even involve Support, Assurance and Safety roles. Interactions are explained in the activities. 

2.1 Agency Level Management

Agency Level Activities are intended to provide "enabling support" to project teams. These activities include direction, guidance and support along with some funding to project teams.
