System Development and Life- Cycle Management (SDLCM) Methodology Handbook, Version 2.3 July 2002 UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, DC SDLCM Methodology Handbook Foreword Nuclear Regulatory Commission (NRC) Management Directive 2.5, “Application Systems Life- Cycle Management,” establishes the policies for applications systems life-cycle management. The System Development and Life-Cycle Management (SDLCM) Methodology implements Directive 2.5 by providing life-cycle structure and guidance to NRC Projects. The SDLCM Methodology comprises seven components: 1. Define Initial Project Requirements 2. Acquire Support Resources 3. Design the Solution 4. Engineer the Solution 5. Deploy the Solution 6. Service the Solution 7. Decommission the Solution The methodology is not Itself a document or a set of documents. It is the approach to doing business at NRC, and it is described by a set of documents, including but not limited to the following: SDLCM Methodology Handbook SDLCM Methodology Procedures, Standards, and Forms SDLCM Methodology Tool Inventory SDLCM Methodology Overview Training SDLCM Methodology iii Handbook, Version 2.3 SDLCM Methodology Handbook Table of Contents 1.
