How to run a campaign post-mortem
One hour, within a fortnight of the campaign ending, with the person who answered the phone in the room. Four questions in order, and the first three usually explain the fourth.

A campaign post-mortem is one hour, held within a fortnight of the campaign ending. Four questions, answered in order. Did enough of the right people see it. Did it make them act. Did we answer them. Did we close them. Most owners jump to the fourth and conclude the advertising failed. In practice the answer is sitting in the second or the third, and the person who knows it is the one who was answering the phone.
Start with what actually ran
Not what was planned. What ran.
This is the least glamorous part of the meeting and it explains more disappointing campaigns than creative ever does. Put the media plan next to the proof of execution and read across.
The hoarding was booked from the first of the month and the flex went up on the ninth. The radio schedule promised a morning band and half the spots aired after eleven. The insert was ordered for six pincodes and the delivery network covered four. The cinema slide ran in the wrong reel position for the first week. The landing page went live three days after the campaign started, and the phone number on the hoarding rang to a mobile that was off on Sunday.
Ask for dated photographs, station logs, insert receipts and screenshots. Where the seller cannot produce them, write that down too, because it decides whether you buy from them again.
The four questions, in the order that matters
Did enough of the right people see it. Delivery against what was ordered, and whether the audience was the one you meant. A slide in a Whitefield multiplex delivered perfectly to people who will never drive to your Vijayanagar showroom is a delivery success and a planning failure.
Did it make them act. Calls, walk-ins, forms, WhatsApp chats, scans, and searches for your name, read week by week against the weeks before the campaign. The shape of the line matters more than the total.
Did we answer them. Missed calls. Time to first reply. How many WhatsApp messages were never returned. How many enquiries arrived on Sunday when nobody was watching. This is the question that changes the verdict most often.
Did we close them. Quotations sent, quotations followed up, what people objected to, and what they bought instead.
Work through them in that order and do not let the room skip ahead. A campaign that produced 180 calls of which 60 were never answered has not told you anything yet about the media.
Put it on one page
| Question | What we planned | What happened | Evidence | What it tells us |
|---|---|---|---|---|
| Seen | 11 sites, 90 days, lit | 11 sites, 82 days, 2 unlit for a fortnight | Dated photographs | Delivery short, ask for credit |
| Acted | Calls to rise | Calls rose in weeks 3 to 7, flat after | Call log by week | The offer tired before the cycle ended |
| Answered | Reply within the hour | 22 percent of calls missed after 7pm | Telephone report | The gap is ours, not the medium's |
| Closed | Site visits booked | Visits booked, few converted | CRM | The enquiry was fine, the quotation was slow |
The numbers in that table are an illustration, not a result. Fill it with your own and it becomes the only campaign document anybody reads twice. Putting the delivery, the response and the follow-up on one page every month is campaign analytics and performance reporting.
Separate the decision from the outcome
Some campaigns are well bought and unlucky. A Kannada release your cinema weeks were built around gets pushed by a fortnight. A road you bought is dug up for a utility line. A competitor launches an offer in week two. A campaign judged only on the outcome teaches your team to be timid, and the next plan will be duller and no safer.
So ask two separate things. Was this a sensible decision given what we knew in August. And what do we know now that we did not know then. The second question is the actual output of the meeting.
The questions that get the honest answers
Ask the receptionist what callers asked. Not whether calls came. What they asked. "Do you have parking", "is it the same price as the one in the paper", "are you open on Sunday". That list is the brief for the next advertisement, and it is free.
Ask the salesperson which call they dreaded. Ask the media buyer what they were uneasy about in week one and said nothing about. Ask everyone what they would spend the money on if it were theirs.
None of these appear on a dashboard, and all of them change the next plan.
A worked example
A furniture showroom in Vijayanagar runs a Deepavali campaign: a hoarding on the main road, an insert in five pincodes, and search advertisements. Footfall rises but orders do not. The post-mortem finds the hoarding went up eleven days late, which cost the first weekend. It also finds that 30 of the insert enquiries came by WhatsApp on Sunday and Monday, when the showroom's WhatsApp was on a phone in the manager's drawer. The media was fine. The next campaign's first fix costs nothing and has nothing to do with advertising.
When it is not worth the hour
A two-week campaign with no baseline and no tracking will not support a review. Hold a ten-minute version, write down the two numbers you wish you had, and set them up before the next one starts. We record enquiries by source, reply time and conversion before any work begins, because a post-mortem with no before is an opinion with a table.
What to do next
Put an hour in the diary for the fortnight after your current campaign ends. Invite the receptionist. Ask for the proof of execution from every seller now, while they still have it. Then run the four questions in order, and resist the urge to start at the last one. If you would rather somebody outside the argument chaired that hour, book the free audit and we will read the campaign with you.
