Legacy Reverse Engineering

Turning Complex Information into Actionable Blueprint

Legacy systems remain the source for “differentiating business capabilities”, with embedded business rules & data classified as “can’t survive without” & with little or no documentation. Being unable to meet the needs of the “Digital” and unable to Scale horizontally and vertically, Legacy systems may be challenging the “Business Growth”.

SwiftAnt leverages its Business Systems Analysis prowess, consulting capabilities, well defined methodology to help Clientele in capturing the business rules across the legacy systems, their inter-dependencies, as-is model, gaps with to-be model, holistic solution architecture thus co-creating the roadmap to Digital transition.

Myths / Perceptions / Challenges

Legacy systems analysis is very complex, costly and needs a lot of time.
Reverse Engineering, Re-Engineering & Forward engineering for transitioning to Digital requires specialized vendors (thus costly and time consuming)
Most Reverse Engineering projects turn out to be failures.

Digital Transformation

Our Approach
Our Approach towards Legacy Reverse Engineering projects: With Large Enterprises, often “Core Business Logic” is a mix of:

Tacit knowledge
Several Spreadsheets and associated manual processes
Several systems, with little or zero code documentation

SwiftAnt’s approach is to:

Set the direction
Analyze
Document & Discuss
Detailed Model Capture

Case Studies

Activity	Purpose	Deliverables	Responsible
Agree on Maxims	Establish the key priorities for the project and identify guiding principles that will help the team to stay on track.	Mini Charter for every functional module	SwiftAnt and Client Project Managers
Identify the Personas	Understand who is using the system and why is it important for them and what aspects are most important for them.	User personas (internal and external)	SwiftAnt and Client Project Managers
Appoint a Navigator (Business & Technical)	Appoint a specific person whose responsibility in role of navigator is to ensure that the business architectural vision is maintained throughout the project duration (minimal changes are acceptable).		Client Project Manager
Speak to the Roundtable	Hold brief, regular round table meetings.		SwiftAnt Project Manager
Identify the most valuable first	Start working on the aspects which are most valuable to the project first.		SwiftAnt and Client Project Managers
Identify what can be left as-is	Which aspects of the system should be left in their current state (such that time and resources aren’t wasted where not necessary)		SwiftAnt and Client Project Managers
