Why does a quote show 45 days when the case procurement cycle is 59?

Answer: The quote covers workshop time only, at 44 to 47 days. Quotation, inspection and booking add about 12 days owned by the buyer and the forwarder.

Can sampling be cut from 12 days to 5?

Answer: No. Tool machining at 6 days is already near the floor, and a 3D printed shell cannot replace a moulded sample because size and shrinkage differ, costing 7 extra days in tooling.

How much does Spring Festival add to the cycle?

Answer: 30 days. The moulding floor stops from 20 days before the holiday to 10 days after, taking 59 to 89, so orders aimed at post-holiday stock go in 45 days ahead.

Why does booking double in peak season?

Answer: From September to November carriers release slots in 7 days instead of 3, cut-off moves 2 days earlier and trucking queues 2 more, turning 7 into 14. Float of 2 days vanishes and the table runs 66 days.

Which node should move first to reach 45 days?

Answer: The 5-day sampling and tool-base overlap, because it adds no cost and only needs earlier scheduling. Next is the 3-day booking overlap, and resident inspection last at 4,000 yuan.

Case Procurement Cycle: Case Procurement Timeline

Quick answer: A case procurement cycle runs 59 days from order to put-away, and 19 of those days sit outside the workshop while sampling and tooling chase each other.

FAQ

1. Six nodes: splitting the 59 days

The 59 days are six blocks joined end to end, not one run of machining. Quotation takes 5 days, sampling 12, tooling changes 7, production 25, inspection 3 and booking 7, which sums to 59, and only the 25 production days occupy a moulding machine.

The start trigger of each node matters more than its duration. Quotation starts on drawing and quantity confirmation, sampling on the sampling fee clearing, tooling on the signed sample review, production on the sealed sample, inspection on goods being ready, and booking on inspection release.

Node	Days	Starts on	Output
Quotation	5	Drawing, qty	Price sheet
Sampling	12	Fee paid	3 samples, size report
Tooling change	7	Review signed	Revised sample
Production	25	Sample sealed	First 1,200 units
Inspection	3	Goods ready	AQL report
Booking	7	Release	Slot and bill

Those are single-block times, not worst cases. On a repeat order with the same tool, quotation and sampling merge and the cycle drops to 47 days.

2. Sampling 12 days and tooling 7 days

Inside the 12 sampling days, tool machining is 6; scheduling 2, trial shots 2 and courier 2. Inside the 7 tooling days, bench work is 2, the wait for a signed review 3 and rescheduling 2. That leaves 8 workshop days out of 19.

Five of the 19 days wait on the buyer: review 2, colour approval 1, sample sign-off 2. No supplier schedules them and no approval workflow owns them, so they become a silent loss.

First-pass yield decides how stable the 19 days are. About 65% of samples pass on size and appearance, one rework adds 7 days and two add 15, and nearly all the variance comes from this block.

Lay the 19 days on a calendar and three gaps appear: 3 days from dispatch to receipt, 2 from receipt to a signed review, 2 to get the machine back after tooling. Those 7 days belong to nobody's capacity and nobody's approval queue, so they simply disappear. Writing them into the contract schedule, with an expediter tracking each, is how they come back out of the 59 days, because waiting never enters a schedule by itself.

3. Only three critical items

The critical path is not the longest chain but the one with no float. Three of the six nodes have zero float: tooling after sampling, hardware arrival and the booking slot. The other three carry 1 to 4 days of slack.

Critical item	Depends on	Float	Cost of one day
Tooling change	Signed sample review	0	Whole table slips 1 day
Hardware arrival	Supplier material prep	4	Enters the critical path
Booking slot	Inspection release	2	Zero in peak season
Inspection	Production finish	1	Report must be same-day

The 4 days of hardware float is eaten first. Latches and wheels are bought out, and one late delivery of 6 days forces production to wait 2, pushing the cycle to 61 days. Order the material during sampling, not after sealing.

Booking float drops to zero from September to November. Slots tighten, 7 days becomes 14, and the table stretches to 66 days while the 25 production days never move.

A late item on the critical path is not a day late, it is a batch late. Covering a 1,200-unit gap by switching sea freight to air adds 28,000 yuan, four times what compressing the cycle saves in labour.

4. Adding a 10% buffer: 59 to 65 days

The 59 days describe a smooth run, not a date anyone can promise. A 10% buffer is 5.9 days, rounded to 6, so the customer promise is 65 days while internal planning stays at 59.

The buffer cannot be spread evenly. One day each puts 3 days behind hardware that already has 4 days of float, while tooling gains only 1.

Put the 6 days in three places: 2 on sampling, 2 on tooling, 2 on booking. None of them is under your control: sampling waits on a review, tooling on a signature, booking on a carrier.

Record every draw. If the sample is unsigned on day 30, sampling has spent its 2 days, so chase the review or move the promise from 65 to 70 days.

5. Peak season slip and the two compressions

Peak season slips booking first and then spreads into production. From September to November, booking goes from 7 days to 14 and the table stretches to 66; around Spring Festival the moulding floor stops for 30 days between 20 days before and 10 days after, taking 59 days to 89.

Slip is not days added to the tail but a start date moved forward. To land before the holiday, order 45 days ahead rather than 59, because material feeding stops 20 days before it.

Compressing a case procurement cycle takes two moves worth 14 days. The first is parallel work: overlap 5 of the 12 sampling days with tool-base preparation and 4 of the 7 tooling days with first-batch material prep, provided a matching tool base and 2 t of resin exist. The second is pulling work forward: inspection squeezed from 3 days to 1 with a resident inspector, and 7 booking days overlapped with the last 10 production days by shipping in rolls.

Move	Overlap or pull-in	Days saved	Condition	Cost
First	Sampling/tool base	5	Matching base	Sample may reopen
First	Tooling/material	4	2 t resin ready	Resin returns
Second	Resident inspection	2	Inspector on site	4,000 yuan
Second	Booking over production	3	Rolling shipment	800 yuan rebooking
Total	Five overlaps	14	59 days becomes 45	Buffer stays at 10%

45 days is not a limit but the result of doing both. One move alone lands at 50 or 54 days, and doing neither leaves 59 as a number on paper only.

At 45 days the buffer becomes 4.5 days rounded to 5, for a 50-day promise, since waiting takes a larger share of a short cycle.

Conclusion

A case procurement cycle lives on one sheet: six nodes, six start triggers and three critical items. Quotation 5 days, sampling 12, tooling 7, production 25, inspection 3 and booking 7 add to 59, and 7 of the 19 days between sampling and tooling belong to nobody. Add a 10% buffer for a 65-day promise; peak booking doubles to 66 and the holiday stoppage takes it to 89. Compression has two moves only, 9 days from parallel work and 5 from pulling work forward, bringing 59 to 45 with 5 days of buffer and a 50-day promise. Paste it into the expediting sheet, fill days, trigger and owner on every row; a blank row means the date is not real.
