20. DATA MANAGEMENT APPLICATION LIFE CYCLE (DMALC) We’ve now completed our coverage of the main data management approaches used in Industrial Engineering. anual spreadsheet database Web ased database • manual, spreadsheet, database, Web-based database Whatever the approach, DM applications are always employed within the larger context of designing a system or process to meet a specific need. Let’s examine a general system/process life cycle model for IE, then look at how data management applications “ it” within this framework 2010 John P. Shewchuk ISE 3024 Course Notes 20 – 1 fit within this framework.

20.1 System/Process Life Cycle for Industrial Engineering he solution to most problems encountered in Industrial The solution to most problems encountered in Industrial Engineering is some form of system or process. Each such solution will have a life cycle associated with it. The system/process life cycle will consist of a sequence of tages (steps), starting with problem definition, proceeding stages (steps), starting with problem definition, proceeding through analysis, design, and implementation, and ending with system/process maintenance and evolution. Let’s take a brief look at this life cycle. 2010 John P. Shewchuk ISE 3024 Course Notes 20 – 2

Investigation to get better 1. PROBLEM STATEMENT 1. PROBLEM STATEMENT understanding of problem, ensure it is in fact the problem, odify as required. 2. INITIAL STUDY (ANALYSIS) modify as required. LOTS of data gathering: 3. DESIGN • company background, operations, mission. rganizational structure 4. IMPLEMENTATION organizational structure, players, roles. • constraints – budget, 5. TESTING & EVALUATION personnel, software, etc. • existing policies, procedures, ethods legacy systems 6. OPERATION 7. MAINTENANCE & 2010 John P.
