Process design

Process review and diagnostics

Quick answer

A process review maps how a process such as purchasing, invoicing or payroll really runs today, measures where it loses time, money or control, and ranks the fixes by impact, using Lean Six Sigma tools such as DMAIC and FMEA. NeX starts most clients with a fixed-fee Process Health Check covering two core processes, delivered as a current-state map, an issue and control-gap log and a fix roadmap.

When a process review makes sense

  • Month-end close takes more than a week, or numbers change after they are reported.
  • Stock, receivables or payables do not reconcile without manual adjustments.
  • Approvals happen on WhatsApp or email and cannot be traced later.
  • You are about to choose or change an ERP and want the requirements right first.
  • Auditors, investors or a parent company have raised control observations.

What we review

We walk through each process with the people who run it, then test what they told us against a sample of real transactions. For each step we record who does it, what triggers it, which system holds the record, how long it takes, and which check, if any, prevents errors or fraud.

AreaWhat we look for
FlowHand-offs, rework loops, duplicate entry, waiting time
ControlsApprovals, segregation of duties, reconciliations, access rights
DataMaster data quality, spreadsheets outside the system, manual journals
SystemsWhich steps the current software supports, and which it forces offline
PeopleSingle points of failure and undocumented knowledge

Tools we use

We use recognised Lean Six Sigma tools, scaled to the size of the problem:

ToolWhat it does in a review
DMAICStructures the work: Define the problem, Measure the current process, Analyse root causes, Improve the design, Control it with measures and owners
FMEA (failure mode and effects analysis)Lists how each step can fail, scores severity, likelihood and detectability, and ranks the risks so controls go where they matter most
Process mappingSwimlane maps of current and future state, showing hand-offs between teams and systems
Root-cause analysisFinds why a problem recurs, rather than fixing the symptom each month

What you get

  1. Current-state map for each process reviewed.
  2. Issue and control-gap log, each item rated high, medium or low.
  3. Fix roadmap that separates quick wins, process changes and system changes, with suggested owners.

The Process Health Check covers two core processes, starts at ₹1,00,000 (SGD 1,333) and typically takes about 2 weeks. These are starting prices. The actual fee depends on scope and is agreed case by case before work starts. If you go on to redesign, the review becomes the Discover stage of our 5D method, so none of it is repeated.

Frequently asked questions

Do you use DMAIC and FMEA?
Yes. DMAIC gives each review a clear structure from problem definition to control, and FMEA (failure mode and effects analysis) ranks what can go wrong at each step by severity, likelihood and detectability, so fixes and controls target the highest risks first.
What do we get at the end of a process review?
A current-state process map for each process reviewed, an issue log with each problem rated by impact and risk, a control-gap list showing which checks are missing or not working, and a prioritised roadmap of fixes with owners.
How much of our team's time does a review need?
Usually a 60 to 90 minute walkthrough with each process owner, a short follow-up, and access to a sample of transactions and reports. We do the mapping and analysis.
Can a review be done remotely?
Yes. Walkthroughs work well over video with screen sharing. For warehouses and factories we prefer one site visit where possible. Out-of-pocket expenses for visits are agreed case by case in the engagement letter before the project starts.
