Digital Transformation
Moving a manual or legacy operation onto software, in a sequence the organization can absorb.
Overview
This work starts where an operation still runs on spreadsheets, paper forms and a system nobody is willing to change. The risk in moving it is not the new software but the period when both systems are live and the records disagree. The sequence is the design decision: what moves first, what keeps running untouched, and what is retired only after a period closes.
- Process mapping against the work as it is actually done
- Data extraction, cleaning and backfill from spreadsheets and legacy databases
- A system of record and the master data model under it
- Integration with the systems that are staying
- Parallel running and record-level reconciliation
- Cutover and rollback planning, one process at a time
- Roles, permissions and the audit trail the old process kept on paper
What you receive
- 01A process map naming every step, its owner and where it lives after cutover
- 02Migration scripts with the cleaning rules recorded, rather than corrections applied by hand
- 03Reconciliation reports comparing the old records against the new on every parallel cycle
- 04A cutover plan per process, with the rollback path written before the switch
- 05The working system with historical data loaded, not only new entries
- 06A retirement note: what the legacy system still holds, who reads from it, and what moves before it is switched off

How the engagement runs
The engagement opens with a read of the operation where the work is done, not of the document that describes it. Some of what it finds does not need software, and the read says so. The processes are then ordered: the one whose data is cleanest first, then the ones that depend on it, and the system of record last. Each process moves the same way. It is built alongside the old one and run in parallel until the reconciliation is clean, then cut over with the rollback path left open. The old system is not switched off because the new one is live. It is retired once its reports have been reproduced and a period has closed.
- The operation stops depending on the person who knows the exceptions.
- A process change becomes a release rather than a message asking people to work differently.
- Reports are produced from one set of records, not assembled from several.
- The legacy system can be retired as a decision rather than tolerated as a risk.
