- Most modernisation proposals look impressive on paper but fail when hitting real databases.
- Vendor differences only emerge six months into the project execution phase.
- Effective questions demand specific names, dates, and trade-offs rather than generic values.
- Evaluate delivery milestones, compliance in the UAE, and knowledge transfer plans before signing.
Every modernisation proposal looks good on page one. There is a confident timeline, a diagram with arrows pointing towards the cloud, and a team slide full of smiling people you may never meet again after the kickoff meeting.
If you run technology at a mid-sized company in the UAE, you will probably sit through several of these pitches before you choose a partner to help modernise a legacy system. The proposals start to blur together, and differences only show up six months later when the plan meets your actual database.
Legacy modernisation is a critical milestone for digital transformation. Selecting the wrong partner introduces severe financial and operational risks, making rigorous vendor due diligence through targeted questioning an essential step for technology leaders.
Here are the questions that tend to separate a partner who will finish the job from one who will finish the slide deck, covering vital operational and technical dimensions:
- Request a named list of personnel and their weekly time commitment.
- Inspect their code discovery and data profiling methodologies.
- Demand an early, small-scale production release milestone.
- Examine specific architectural trade-offs and alternative solutions.

In the UAE, where data residency and compliance matter intensely, especially across banking, insurance, healthcare, and government-linked sectors, these security questions must be addressed during the initial conversations rather than right before go-live.
"A plan where nothing reaches production for nine months is a plan to discover problems late and expensively."
