There are very few successful businesses that can operate the same business model or even maintain the same organizational structure as they mature and their business grow (or even shrink).
Periodic reviews or the status quo of the business versus the business plan and strategy are necessary to ensure that the organization is positioned to meet its objectives whilst keeping up with resource desires and motivators.
Senior managers are often reluctant to acknowledge the need for such change, however by bringing an independent consultant in to ‘own’ a reengineering project all stakeholders are assured of an independent view for where the company could be going.
Reengineering involves adopting a completely new architecture and technology whilst retaining the core business functionality of the existing application. The complexity in such projects is that the business rules are frequently embedded in huge legacy systems written decades ago. Over the years, many such applications lose their relevance in the context of changing business environment.
Applications that were custom developed in the past and modified from time to time without keeping the documentation updated also lead to another set of problems. All of this leads to avoidable high costs of application maintenance and also add to the risk of outages with serious consequences as old applications are unable to stay adept with changing requirements or are unable to interface with new systems.
When it is considered that over 80-85% of the core business rules may not change, adopting the traditional development route makes the entire project highly expensive and risk prone.
TSI works within your brief and consults various levels across the organization to ensure the process is accepted, beneficial and as least disruptive as possible whilst taking it a step further to manage the transformation and change together with you.
TSI follows a widespread re-engineering methodology that is flexible for individual situations. The business rules extracted from the legacy systems are used as foundation to derive the business rules and requirements for the new system. The entire environment is established, ensuring that requirements are not neglected in the new system.
Upon release of the finalized requirements for the new system, a Re-engineering of the complete end-to-end solution is undertaken. This solution offers re-engineering of presentation, business logic, and data from the legacy environment to an open, business-driven, flexible target environment. UI and workflow typically changes completely in the new system. This approach brings in the advantages of legacy comprehension in terms of retaining and reusability of legacy system business rules along with the flexibility to move forward with the latest state-of-the-art technology/platform options based on the principles of the SOA architecture.
Application Migration provides the solution for platform rationalization in the form of either upgrades or completely switching over to a new language or database or platform. With the fast changing business scenarios, organizations globally are faced with challenges requiring them to upgrade their applications and/or legacy systems with the latest technologies. Application Migration quickly and efficiently moves applications to modern platforms with the latest architectures and designs while preserving original goals and application logic.
In a migration approach, in most cases, the prime focus is on the database access logic rather than the entire application logic. The key thing in migration is impact assessment and degree of process automation. Depending on the findings of the Assessment Study a combination of migration and re-engineering may be required.
