In short: A joint business plan holds volume, range, promotion and investment commitments for a defined period, which a rolling trading agreement does not. Most plans fail in execution because commitments and aspirations sit in the same list with no marker between them, so supply ends up planning against numbers nobody intended as firm. A range commitment is a supply commitment, and agreeing distribution for six new items in September without a capacity conversation books a shortage for February. Changing the sequence, so supply sees the volume and range implications before the plan is signed rather than after, does more than any improvement to the document itself.
The meeting happens in September. Two commercial teams, a deck that took three weeks to build, a set of category ambitions, a promotional grid for the year, a list of new items going in and a handshake at the end of it. The document gets circulated, filed, and opened again eleven months later when somebody starts building next year's version.
In between, the supply planning team finds out about the range commitment when an order arrives in February for six items that are not in the production plan, at a volume that assumes 400 stores, in the same week as a promotion on the existing range that was agreed in the same meeting.
The document was probably a good one, in the sense that a reader could tell what both parties had agreed to. The problem is that it was agreed by people who could not deliver most of it, and handed afterwards to people who had no part in shaping what was promised.
What a joint plan holds that a trading agreement does not
The trading agreement is the enforceable part. Price, terms, payment days, rebate structure, listing fees, logistics arrangements. It is drafted by people who draft for a living and it will be read carefully by both sides if anything goes wrong.
A joint plan is doing something the trading agreement cannot, which is describing what both parties are going to do to grow the category and what each has to deliver for that to work. The parts that make it worth having are these.
Shared category objectives with a measure attached. A stated target on a metric both parties can see and can agree the source of, which is a harder thing to write down than a growth ambition and a more useful one to review against. The idea of planning against a category objective rather than a brand objective came out of the category management process published under the joint industry Efficient Consumer Response programme in 1995, and the discipline in it that survives is the insistence on defining the category first and agreeing what success looks like for the category before anyone negotiates their own share of it.
An agreed promotional calendar with expected outcomes. Dates, mechanics, coverage, and the volume each event is expected to deliver. The expected outcome is the part that is usually missing, and without it there is nothing to review against. How that expected outcome should be estimated, and how the actual is measured afterwards, is a method with its own post on this site.
Distribution and range commitments with dates. Which items, in how many outlets, live by when. A range line with no date is a wish, and a range line with no outlet count cannot be converted into a supply requirement.
A review cadence with named owners. When both sides look at this, who attends, and what they are expected to bring.
Commitments and aspirations in the same list
Every joint plan contains two kinds of statement. One party will do a specific thing by a specific date and can be held to it. And both parties would like a certain outcome and will work towards it. Both belong in the plan. Putting them in the same numbered list damages both.
What happens is straightforward once you have watched it. The list contains twelve items. Four of them are enforceable, eight of them are directional. In the quarterly review, nobody can enforce the eight, so the meeting develops a norm that items on this list are discussed rather than delivered. That norm then applies to the four that were real, and the range commitment gets the same shrug as the ambition to grow premium penetration. Meanwhile, somebody on the other side treats an aspiration as a promise, brings it up as a failure, and the meeting spends forty minutes arguing about something neither party ever agreed to do.
The fix is to separate them physically and to use different verbs. Commitments read like this: we will have six items listed in 400 stores by 1 March, we will run four feature events on the agreed mechanics, we will maintain stock cover of at least three weeks at the depot. Each has an owner, a date, a number, and a stated consequence if it is missed. Aspirations read differently: we intend to grow the premium segment ahead of the category, we want to improve the shelf position of the core range at the next reset.
Count them before the meeting. A plan with thirty commitments has none, because nobody tracks thirty things across a company boundary. Six to ten real commitments per side is a plan somebody can actually hold in their head.
Managing the plan during the year
The default failure is reconciliation at the end. Eleven months pass, the annual volume comes in somewhere near the number, and the review concludes that the plan broadly worked.
The annual total hides almost everything worth knowing. Half the range can land six months late, the promotional plan can be rebuilt three times, the distribution commitment can be quietly abandoned in two regions, and the volume still arrives because the gap got filled with extra promotions that cost margin nobody planned to spend. The number lands and the plan failed.
Tracking against the plan during the year needs three things and none of them are elaborate.
A monthly view of commitment status. For each commitment, what was due by now, what has landed, what is at risk, with a named owner on anything amber. This is a one page artefact and it should be the first item in every internal customer review, ahead of the volume number.
Measures that match the commitments rather than the total. Distribution achieved against distribution committed, counted as live item and outlet combinations rather than as a percentage somebody estimated. Promotional events executed against planned, with a flag when the mechanic changed. Volume against the agreed phasing rather than the annual figure, because a plan that is 100 percent on the year and 60 percent in the first half is a supply problem wearing a good result.
A versioned plan. Keep the agreed baseline and the current working view as separate versions rather than editing one document, so that the mid year reset does not silently overwrite what was agreed in September. This is the same argument for scenario overlays that applies anywhere else in planning, and it matters more here because the other party has their own copy of the original.
Cadence that works in most businesses: monthly internally, quarterly with the customer, and one honest mid year reset where commitments that are clearly dead get killed rather than carried.
A range commitment is a supply commitment
This is the part that gets lost between the two rooms, and it is arithmetic rather than judgement.
Six new items into 400 stores, each store carrying roughly six units on shelf, is around 14,000 units of pipeline fill before a single consumer buys anything. Add depot cover of three weeks at the expected rate of sale, add the safety stock to protect a new item with no history and therefore a wide forecast interval, and the requirement is meaningfully larger. All of it lands in one or two weeks, because listings go live on a reset date.
Spread across a year that volume is trivial and it will pass every annual capacity check you run. Concentrated into the fortnight before a range reset, competing with the promotional volume agreed in the same meeting for the same lines and the same production assets, it becomes a capacity problem with a fixed date and a commercial consequence for missing it.
Promotional commitments behave the same way. An agreed mechanic on an agreed date is a booking against finite capacity, and four customers with independently agreed calendars can converge on the same production week without anyone having done anything wrong.
Range commitments also create a standing exposure that outlives the plan. Committing to keep a slow selling item listed in a wide distribution means holding stock against it for as long as the commitment runs, and in a category with dated stock that exposure shows up as write off rather than as inventory. Which items should be in the range at all is a separate assortment question covered elsewhere; the point here is that the joint plan is where the decision actually gets made, often without anyone recognising it as one.
The artefact that fixes most of this is small. Every commitment in the plan carries a volume, a date, and a field recording whether supply has confirmed it. Commitments without that third field are proposals.
Sequencing, which is the actual fix
The instinct after a bad year is to rebuild the template. Better sections, clearer owners, a tracking spreadsheet with conditional formatting. It rarely changes anything, because the document was not the problem.
What changes the outcome is when supply sees the commitments. Concretely, three or four weeks before the customer meeting, the draft commercial plan goes to supply planning with the range and promotional commitments expressed as volumes and dates. Supply comes back with what is available to commit: which listings can be supported on the proposed date, which need two weeks of movement, which promotional weeks are already full, and what the cost is of forcing any of it. The commercial team walks into the room with a list of what they can offer rather than a list of what they hope to.
Add one standing rule for the meeting itself: anything committed in the room that was not in the pre reviewed list is provisional for five working days. That single sentence, agreed with the customer in advance as a normal way of working, removes most of the damage from the enthusiasm that these meetings generate. Customers accept it readily, because they have the same problem internally.
The whole change is a calendar change and a two page handover. It costs a few days of planner time per major customer per year, against a range launch that missed its reset date.
The limit
Joint plans are agreed by commercial teams and executed by supply chains that were not in the room, and no version of the document solves that. The organisations are separated by function, incentive and meeting calendar, and the sequencing fix above manages the consequence without removing the cause. Expect it to keep leaking, and build the review cadence to catch the leaks early rather than expecting them to stop.
Two other constraints are worth being honest about. Your customer has dozens of these plans and yours is competing for attention against all of them, so a plan the customer does not reference in their own internal reviews is a document you are maintaining alone, however good it is. The signal to watch is whether they ever bring the plan to a meeting you did not organise.
And the cadence dies when the buyer changes, which is outside your control and happens often. The protection is to keep the plan in a form a new buyer can pick up in twenty minutes, which means the live commitment list with dates and status rather than the eighty slide deck from September. Rebuilding the relationship takes a quarter; rebuilding the plan should take an afternoon.
There is also a case where none of this applies. A customer who will not commit to anything specific, because their own internal process does not let them, cannot be moved by a better joint planning process, and running a full annual cycle with them produces an expensive forecast and a relationship document.
Take last year's plan, list every commitment in it, and mark each one delivered, partly delivered, or never mentioned again, because the size of that third group is the size of the problem you are actually solving.
