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

The tabs in this page initially will contain all of the activities in Ch 2 through 5 of NPR 7150.2. This is done to ensure that all SWEs are accounted for. 

As the page matures, Topics, PATs, and other resources will be distributed to enrich the content of the activities. 

SWEs from NPR 7150.2 are reproduced in a floatbox on the right to ensure that all SWEHB content is accounted for somewhere in the view.
