What should count as one workflow case?
Choose a recognizable unit such as one quote, approval, or handoff and define verifiable start and finish events. Keep those boundaries stable before and after a change. Separate materially different case types so a shift toward easier work does not appear to be an improvement in the process.
Separate materially different types of work. A repeat order and a new project with an unresolved specification should not be pooled without explanation.
What is the difference between handling time and elapsed time?
Handling time is active effort on a case; elapsed time is the duration between its defined start and finish. Waiting may involve approvals, customer decisions, availability checks, or an unattended queue. Measure both: reducing preparation effort may leave the customer’s delay unchanged if the same approval still takes two days.
For an illustrative case, a request takes two business days to complete but involves forty minutes of active handling. Reducing document preparation by ten minutes changes effort. It may leave the two-day delay unchanged if the case still waits for the same approval. Both measures belong in the review.
What should a workflow baseline record?
Record the case type, start and finish, active effort, waiting, clarification, correction, outcome quality, and relevant context. The NATA Workflow Baseline below provides a starting log. Explain which cases and period it covers; a small convenient sample should not be presented as representative of the whole company.
| Item | What to capture |
|---|---|
| Case and type | A reference that avoids unnecessary personal data |
| Start and finish | Verifiable events with dates or times |
| Active effort | Who worked on it and for how long |
| Waiting | What the case waited for and who could act |
| Clarification and correction | Additional exchanges and rework |
| Outcome quality | Whether the response met the agreed need |
| Context | Complexity, staffing, or other relevant changes |
Do not present a convenient sample as representative of the whole business. Explain which cases it covers and what it leaves out.
Why is average completion time not enough?
An average can conceal a process that works well for routine requests but fails on exceptions. Inspect individual cases before summarizing, and report counts and periods alongside averages or medians. Match precision to the observation method: rough time diaries do not support finely detailed performance claims.
If you use medians or averages, state the case count and period. Avoid decimal precision that the observation method cannot support. A rough time diary does not become a precise time study because it is placed in a chart.
How do you check whether an improvement moved work elsewhere?
Review effects on the people before and after the changed step, including customers. A team may save time by passing cleanup to operations or introducing a difficult customer form. Pair their account of the change with case records to see whether the full journey improved.
Ask the people affected what became easier and what became harder. Pair that feedback with records. Satisfaction alone does not establish a time saving, but a time saving that damages the buying experience deserves attention.
Are hours saved the same as financial savings?
Released hours create capacity unless an actual cost changes. If staff remain on the same paid hours, payroll has not fallen by the time released. Cash savings require evidence of lower spending; additional revenue requires evidence that the capacity contributed to sales or delivery.
Record the benefit you observed rather than the largest number you can calculate from it.
How do you decide whether to keep a workflow change?
Compare the observed result with success and concern conditions stated before the trial. Consider other changes such as staffing or project mix. Then record a decision to continue, adjust, investigate further, or reverse, with the evidence and remaining uncertainty that support it.
The useful outcome is a decision with a basis: continue, adjust, gather more evidence, or reverse. Measurement has done its job when the business can explain that decision without hiding uncertainty behind a single savings figure.
Frequently asked questions
How many cases are enough to prove a workflow improved?
There is no universal case count in this guide. State the sample, period, case mix, and limitations. A small trial can inform the next decision without supporting a claim about the entire business.
Can a time saving be attributed entirely to a new tool?
Only if the evidence supports that attribution. Staffing, complexity, work volume, and other process changes may also affect results. Record those conditions rather than treating every before-and-after difference as the tool’s effect.
What should you do if speed improves but errors increase?
Compare the change with the success and concern conditions agreed for the trial. Include correction effort and customer consequences. Faster handling alone is not sufficient evidence to keep the intervention.
