Business System Analysis Methodology Presentation

The following scenario will be addressed: a. Getting what you do not have: (Integrated system to manage the maintenance department spare parts and work orders). b. Getting rid of what you do have: (Poor spare parts inventory management and unneeded legacy system).

 prototyping and reverse engineering of the current Perzak legacy system  developments learned in the legacy system will provide a quick development program that will be much more faster to implement  Microsoft Visio  UML Methodology  OO Techniques

 Constraints: time, money, and functionality  Prior to implementation, all functions must be drafted first

 Non-IS Influences  A development team must know how to anticipate unforeseen circumstances  Resource Limits  The development team must know its capability to estimate who will do what and the timeframe to achieve the stipulated objective in the contract

 Cost - Benefit Analysis  When expertise is available, reverse engineering is fast  Net Present Value and Cost/economic analysis  The net present value is positive. If it were negative, the project must be disregarded anyway.

 Least Cost Alternative  During reverse engineering stage, working in-house requires longer time and is expensive for the company  Decision evaluation matrix  The decision whether the business must move forward or wait with the idea in the application is made

 Risk analysis  To know the risks and how it will affect the company, the group must distribute the risks into their accurate category

 Tangible and Intangible Benefits  Reverse engineering will allow the company to save money  The information generated is up-to-date in real time  All employees will be trained on the usage of the new application before implementation of the new system

 Process for handoff to development and implementation teams will be provided.  A schedule must be available for post implementation audit.  Each organization functions to maximize its efficiency and minimize losses.  Inconsistencies is harmful for business interests.
