Activewear: Planning Newness and Continuity Together
Activewear merchandise planning needs room for new colours without underfunding the permanent lines customers return to buy. Core connects continuity, ranges, budgets and MFP/WSSI. Plan the two demand roles separately, then reconcile their cash, intake dates and size depth within one accepted buying envelope.

THE MERCHMIX DECISION / Core
Newness needs a place in the budget, not the whole budget.
Protect the accepted continuity requirement and bound the new-colour test.
Independent worked retail example. Quantities are planning assumptions, with financial amounts shown in US dollars. Proposed changes remain subject to review.
Newness needs a place in the budget, not the whole budget.
The base uses 180 continuity and 200 colour units, costing $11,400. A 250-unit colour test costs $12,900 combined. At seventy continuity sales a week, the original test costs $12,600 combined. No buy is committed.
Continuity needs 180 incoming units in the base plan.
THE KEY IDEA
Protect the accepted continuity requirement and bound the new-colour test.
A new colour competes for more than display space
Newness and continuity can use the same customer budget, factory capacity and stock funding while earning demand differently. A permanent black legging needs repeat availability. A seasonal colour needs a bounded test and a timely exit decision. Treating both as one undifferentiated growth target can obscure which commitment deserves the next dollar.
Core supports continuity groups alongside range and financial planning. The useful distinction is the role of the stock, not whether the product feels exciting in a range meeting. Use each product’s role to assess its claim on the shared buying envelope.
Reserve the repeat requirement before adding the drop
Assume a $12,000 buying envelope at an identical $30 unit cost, equivalent to 400 units. Continuity demand is sixty units per week over four weeks, 240 in total. With 120 usable opening units and a sixty-unit closing target, its intake requirement is 180 units, costing $5,400.
The calculation is demand plus target less opening. It does not authorise an order, but it makes the continuing line’s claim on the envelope explicit. Confirm that its sizes and receipt timing are suitable; 180 late or wrongly assorted units do not deliver the planned availability.
Give the new colour a test that fits the remainder
After the $5,400 continuity requirement, the envelope has $6,600 remaining, funding 220 new-colour units at $30 if all other commitments are already included. A 200-unit colour test costs $6,000 and leaves $600 uncommitted. The two accepted proposals would total 380 units and $11,400.
A 250-unit colour proposal would instead cost $7,500, bringing combined commitment to $12,900, $900 above the stated envelope. The enthusiasm for a launch has not increased the available money. Core’s budget and range comparison should show the trade-off before the proposal becomes a supplier commitment.
THE FIGURES BEHIND THE DECISION
| Base role | Incoming units | Cost |
|---|---|---|
| Continuity | 180 | $5,400 |
| Colour test | 200 | $6,000 |
| Combined proposals | 380 | $11,400 |
| Remaining envelope | 20-unit equivalent | $600 |
Continuity intake = 4 × 60 + 60 less 120 = 180. Combined cost = (180 + 200) × $30 = $11,400.
Do not borrow from continuity without changing its outcome
Cutting the continuity receipt from 180 to 150 would free $900, but closing would fall from sixty to thirty under the same four-week demand. It is a different service and stock plan, not spare money found by relabelling the units. The range owner must decide whether that consequence is acceptable.
Conversely, a credible reduction in continuity demand could change its requirement legitimately. Keep the revised assumption and timing visible in MFP/WSSI. Moving money between roles without explaining the new closing position makes an apparently balanced budget less useful than it looks.
Place a gate between test and repeat
The initial colour test should state when evidence is sufficient for a repeat decision, which sizes remain available and whether another receipt can become usable during the selling opportunity. A strong first weekend can be distorted by launch exposure; a quiet one may reflect missing sizes or limited distribution.
Core supports comparing the range and intake assumptions with the financial plan. A test is not permission to duplicate the full opening quantity automatically. The repeat needs its own remaining-demand estimate, usable stock and accepted funding, alongside the continuity line’s latest requirement.
Stress the continuity requirement before judging the mix
In a separate scenario, continuity demand rises to seventy per week. Four-week demand becomes 280, so the same opening and target require 220 incoming units costing $6,600. Keeping the 200-unit colour test then totals $12,600, which exceeds the original envelope by $600.
That sensitivity is not a sales forecast presented as fact. It tests how a stronger permanent line changes the room for newness. Reducing the test, changing timing or seeking more approved funding are different responses; none should be hidden inside an unchanged total-range headline.
| Signal | Merchmix workspace | Decision to review |
|---|---|---|
| Protect the repeat requirement | Core / decision review | Continuity needs 180 incoming units in the base plan. |
| Add a bounded test | Core / decision review | Two hundred colour units leave $600 in the envelope. |
| Inspect the larger proposal | Core / decision review | A 250-unit colour buy makes combined cost $12,900. |
Review the roles rather than declare one the winner
After trading, compare continuity availability, new-colour sell-through, realised price and closing stock against their own assumptions. A permanent line should not be penalised for having less launch attention, while a colour test should not inherit a long repeat horizon simply because the base style is ongoing.
Merchmix Core connects those roles through one financial plan. The worked base preserves a 200-unit test and an explicit continuity requirement within $11,400. It leaves the $600 balance visible and the next commitment conditional on evidence rather than on a permanent preference for either newness or familiarity.

Common questions
What is the continuity receipt requirement?
240 expected sales plus sixty closing, less 120 opening, gives 180 units.
Does a 200-unit test fit?
Yes under the base assumptions: combined cost is $11,400 against $12,000.
Why not use a 250-unit test?
It would take combined commitment to $12,900 unless another assumption or the approved envelope changes.
What changes at seventy weekly continuity demand?
Continuity intake rises to 220 units and the same test takes total cost to $12,600.
Is the colour test an automatic repeat?
No. Repeat evidence, timing, sizes and funding need a separate decision.
