Mass re-engineering (or platform migration) of an existing application constitutes a very special type of software engineering undertaking. Such a project entails special risks, opportunities and expertise. Quite often, re-engineering projects involve the use of automated impact assessment, conversion and testing tools. Systems Limited has a highly developed and tested mass re-engineering methodology which integrates seamlessly into Systems Limited WorkVision framework. In most cases, the methodology is supported by Systems Limited proprietary or third party impact analysis, conversion, testing and change management tools. The application of these automated tools shortens the project timeframe, reduces the project cost and mitigates the project risks through minimization of human error.
The service covers the entire spectrum of an application re-engineering project as shown in the table below:
Generally, a re-engineering project focuses upon systems vital to the daily functioning of the business. The nature of the work, combined with the size of such systems, usually involves millions of lines of code and large databases. Such projects present, in addition to the basic technical issues, complex issues of planning, logistics, communications and management, the careful handling and integration of which is of critical importance. The methodology addresses both the technical and logistical aspects.
The methodology not only provides the project roadmap to Systems Limited team of professionals undertaking a re-engineering project, but it also provides the management and IS staff of our customers a clear sense of how Systems Limited will complete the assignment and what are the counterpart inputs expected of the customer.
