PREVENTIVE MAINTENANCE TOOLS AND TECHNIQUES FOR ADA SOFTWARE REUSE

THIS EFFORT IS ADDRESSING THE APPLICATION OF PREVENTIVE MAINTENANCE TECHNIQUES AND REVERSE/RE-ENGINEERING TOOLS TO EXISTING ADA SOFTWARE FOR THE CREATION AND USAGE OF REUSABLE COMPONENTS. TECHNICAL OBJECTIVES FOR THE PHASE I EFFORT ARE: 1) DESCRIBE THE RELATIONSHIPS BETWEEN THE SOFTWARE MAINTENANCE AND THE SOFTWARE DEVELOPMENT AND REUSE PROCESSES. SPECIFICALLY, ILLUSTRATE THE POTENTIAL ROLES OF PREVENTIVE MAINTENANCE OF EXISTING SYSTEMS FOR ACHIEVING SOFTWARE REUSE. 2) SHOW HOW VARIOUS MAINTENANCE TOOLS AND TECHNIQUES CAN BE APPLIED TO MAKE EXISTING SOFTWARE MORE REUSABLE. IDENTIFY EXISTING AUTOMATED CAPABILITIES, AND EMERGING TECHNIQUES. POSTUALTE AN IDEAL SUPPORT ENVIRONMENT. 3) IDENTIFY AND ASSESS POTENTIAL COST/BENEFIT TRADE-OFFS, AND OUTSTANDING ISSUES AND RISKS, ASSOCIATED WITH THE PREVENTIVE MAINTENANCE APPROACH. 4) DEFINE A SUITABLE SEMI-AUTOMATED CAPABILITY THAT COULD BE PROTOTYPED IN PHASE II, WITH A GOAL OF COMMERCIALIZATION IN PHASE III. 5) DEMONSTRATE THE FEASIBILITY AND USEFULNESS OF THE APPROACH BY IMPLEMENTING A SUBSET OF THE RECOMMENDED TOOLS AND METHODS. THE PROPOSED SUBSET INCLUDES AN ADA PARAMETERIZER AND COMPLEMENTARY ADA ADAPTOR.
