Restructuring or rewriting part or all of a system without changing its functionality is called system re-engineering. The main reason we suggest system re-engineering to our clients is when we are ready to put effort to make it easier to maintai, When system changes are confined to one subsystem and the subsystem needs to be reengineered, When hardware or software support becomes obsolete and When tools to support restructuring are readily available. We not only re-engineer your system but also do re-documentation for the re-engineered system.
Concerned with redesigning business processes to make them more responsive and more efficient. It relies on the introduction of new computer systems to support the revised processes or May force software re-engineering of legacy computer systems which designed to support existing processes.
Involves analyzing and reorganizing data structures or data values used in a program. This might be part of the process of migrating from a file-based system to a DBMS or changing from one DBMS to another DBMS The goal to create an environment where it is managed not just used.
We analyze data records and values to improve quality, then we remove duplicates, and delete redundant information. Then we applay a consistent format to all records.
We re-engineer data and programs to remove data processing limits. To acheieve this we rewrite data itself to reflect program changes.
We move data to modern DBMS or store in separate files or an older DBMS.
We identify business goals in the context of key drivers including cost reduction,time reduction, quality improvement and empowerment
We identify and prioritize processes critical to achieving business goals.
We analyze and measure existing processes, process costs and time, and then isloate quality/performance problems.
We prepare use-cases for each process to be redesigned and new tasks are designed for each process.
We test processes before integrating them into the business
Based on feedback from the prototype, We refine business processes and then instantiated within a business system
We sort active software applications by business criticality, longevity, current maintainability, and other local criteria to help us identify re-engineering candidates.
Rather than living with weak documentation we update poor documents if they are used or we even fully rewrite the documentation for critical systems focusing on the "essential minimum".
We analyze a program in an effort to create a representation of the program at some abstraction level higher than source code.
We analyze source code and violations of structured programming practices are noted and repaired then we review and test revised code.
We fully reverse engineer current data architecture to dissect it into data models definition and we review existing data structures for quality
We recover design information from existing source code and use this design information to reconstitute the existing system to improve its overall quality or performance
