Correct an Analytical Error After Sending a Client Report
You have sent a process review to the client. While checking the workbook, you discover that two unfinished requests were counted as taking zero hours. The average in the report is wrong, and the client plans to use its conclusion at tomorrow's meeting.
The next decision concerns use of the affected analysis. Establish what is wrong, tell the responsible client contact which conclusion needs to be set aside, validate the correction and find the people who received the original. Replacing your own file addresses only part of that work.
Identify the affected conclusion before rewriting the report
Preserve the exact version sent, its supporting analysis and the available delivery record. Note where the error appears and who found it. Describe the confirmed problem separately from questions you are still investigating.
Check the consequences of the error. A number may appear in a chart, an executive summary and a recommendation. A correct replacement calculation will not fix those places if they still carry the old interpretation.
Assign a person to check the analysis and a person to coordinate the client response. Agree who can approve the corrected issue through your organisation's normal process. For a consequential error, involve the appropriate subject specialist rather than relying only on the original author's recheck.
Work the correction without overstating the new result
The following case, report references, people and actions are entirely fictional. The small dataset illustrates an error; it is not a representative service-performance study or a customer result.
A consultancy sends report SR-14 V1 to a sponsor and an operations lead. Its page 4 chart reports a mean completion time of 4.8 hours across five requests. The summary says that the sample meets the client's six-hour mean target, supporting a suggestion to relax escalation.
The underlying records actually contain:
| Request | Status at the reporting cutoff | Completed duration |
|---|---|---|
| A | Closed | 6 hours |
| B | Closed | 8 hours |
| C | Closed | 10 hours |
| D | Open | Unknown |
| E | Open | Unknown |
The workbook treated D and E as zero. That produced (6 + 8 + 10 + 0 + 0) / 5 = 4.8 hours. The checked calculation for the three closed requests is 24 / 3 = 8 hours.
Neither calculation establishes a completed five-request average. Two completion durations remain unknown. V2 therefore reports the three closed requests' mean of eight hours, identifies the two open requests and withdraws the five-request target-met conclusion. It also withdraws the suggestion to relax escalation on that basis. The three completed observations do not establish performance across the service or predict later results.
Send a precise interim warning through the responsible contact
The client may need to know about the affected conclusion before the complete replacement report is ready. Use the confirmed facts to explain what should be set aside and when the next verified update will arrive. If the scope of the error remains uncertain, describe the investigation that is still open.
In the fictional case, the project lead's initial notice reads:
Please pause use of the 4.8-hour figure on page 4 of SR-14 V1, its summary and the recommendation based on it. Two open requests were incorrectly included as zero-duration completions. We are checking the affected calculations and will provide the correction or an update by the time agreed today. Please tell us whether the report or figure has been forwarded or used in a decision.
Use a return time that the responsible people can meet. Keep the actual notice and its recipients. The message should help the client identify affected work without implying that every other part of the report has already been cleared.
Keep a filled correction register
This is the consultancy's fictional affected-conclusion and recipient register after the check. Keep supporting files in their authorised locations and use references that the responsible colleagues can open.
| Record | Completed entry |
|---|---|
| Original issue | SR-14 V1, sent to sponsor and operations lead; sent file and delivery record retained |
| Error and evidence | Page 4 workbook mean includes two open requests as zero; reviewer checked the five source records and status definitions |
| Corrected result | Three closed requests total 24 hours, mean 8; two open durations unknown; five-request target conclusion withdrawn |
| Dependent content | Page 2 summary, page 4 chart and escalation suggestion checked against the correction |
| Validated replacement | SR-14 V2, with a correction note identifying changed content and the restricted interpretation; independent review recorded |
| Sponsor's use | Sponsor had copied the chart into a draft meeting pack; confirms replacement of the chart and withdrawal of its target-met statement before the meeting |
| Operations lead's circulation | Lead identifies one forwarded copy to an analyst; both receive V2 and acknowledge the correction |
| Remaining consequence check | Project lead asks the sponsor and operations lead whether an earlier decision used V1; both confirm none within the work they oversee |
The known recipient list now contains three people. Record each person's actual response with its date and source. If another forwarded copy is discovered, add it and assign the next action. Sending V2 to the original two addresses would not establish that the analyst had received it.
Distinguish correction receipt from repaired consequences
An acknowledgement tells you what the recipient acknowledged. It does not establish that every downloaded copy vanished or that every earlier decision was revisited. Where a decision has already used the analysis, identify its owner and the review needed; keep that action open until its outcome is known.
In this example, the sponsor confirms the corrected meeting pack before the planned discussion. The analyst confirms that V2 is now the reference for their work. The numerical correction is issued and the known intended uses have been addressed. The register preserves the limits of those confirmations.
When an old copy reappears after confirmation
A later resend is a new event. It does not erase a recipient's earlier acknowledgement of the correction, and it does not make the old analysis current again. Identify the attachment and the work now being requested before deciding what to do next.
In this fictional continuation of the SR-14 case, the sponsor has already confirmed the corrected meeting pack. A week later, they forward the V1 chart with: “Please put this in the next meeting pack.” The attachment contains the withdrawn 4.8-hour figure. The team does not know whether the sponsor wants that visual layout or intends to reuse its content.
Hold the copying of this chart while clarifying the request. Other work that does not depend on it can continue. Keep SR-14 V2 as the verified analytical reference; the incoming attachment is recorded as a received V1 copy, rather than saved over V2.
| Record | Filled continuation | Meaning for the next action |
|---|---|---|
| Earlier correction | Sponsor's confirmation C-2 identifies the corrected meeting pack and SR-14 V2 | Keep this completed acknowledgement and its original scope |
| New event | Message R-9 attaches the V1 chart and requests its use in another pack | New intended use needs clarification; the attachment does not establish a new checked result |
| Clarification | Project lead asks whether the sponsor wants the layout rebuilt using V2's corrected analysis | Copying the old chart remains on hold |
| Confirmed instruction | Sponsor's reply R-10 requests the same general layout with V2's content | Record that precise choice; do not infer permission to restore the withdrawn conclusion |
| Checked output | Reviewer checks pack P-9: mean eight hours for three closed requests; two open durations unknown; no five-request target-met statement | New chart and labels match the verified correction |
| Closed next action | Sponsor confirms P-9 is the pack they will use | Close preparation and handover; retain R-9, R-10, P-9 and the earlier correction history; actual later use remains unobserved |
The clarification can be brief: “The attachment is the withdrawn V1 chart. Do you want its layout rebuilt with V2's corrected analysis? We will keep the three closed requests and two unknown durations explicit.” In the fictional case, the sponsor confirms that choice before the team rebuilds the chart.
A request to restore the old figure would require a different response: identify the known error and involve the responsible project or analytical owner. Do not present a known-wrong result as verified because a customer requested it.
For the next resend, record five things: the received file, the verified reference, the specific requested use, the confirmed instruction and the checked output. An unanswered clarification remains open. Close the instruction-and-preparation task when its checked output has been handed over. That does not establish later meeting use or mean that every old copy has disappeared.
Make the current position easy for a colleague to find
The APM–ACostE Estimating Guide sample chapter, section 2.1.2 discusses tracing analysis from source data to outputs and using proportionate configuration control. That principle supports keeping the sent version, correction and supporting evidence identifiable. The warning and recipient worksheet above is an original operational method, not a mandatory notice procedure drawn from that guide.
Keep the calculation and independent review in your analytical tools. The client relationship record needs a clear reference to the current issue, the correction status and whoever owns any remaining consequence.
When evaluating Konekt CRM, use this fictional case to test whether permitted colleagues can find those three things. Confirm the functions, access and plan needed for your proposed setup. Then ask a colleague to explain which conclusion changed and whether any client action remains open, using the record rather than the author's memory.
