Timber Frame Supplier Under Pressure
A small furniture manufacturer in a regional town builds timber-framed seating for schools. Its main supplier of seasoned hardwood has raised prices 18% in one year and now delivers boards with moisture content averaging 16%, well above the 10-12% the workshop's specification assumes. Two school contracts (worth $140,000 combined) are due in ten weeks. The workshop has one kiln with capacity for 60% of current throughput and cannot afford a second. Staff report joints opening within weeks of delivery, and one client has withheld $12,000 pending rectification. The owner wants to switch to a cheaper imported softwood to protect margin, but the business markets itself on locally sourced hardwood and Australian standards compliance.
1. Identify the structural and technical issues in this situation and explain how they interact.

The technical issue is moisture content: hardwood at 16% will shrink as it dries in service, and shrinkage is anisotropic (greater tangentially than radially), so movement stresses joints and causes checking and warping. The structural issue is that the frame's joint design and fixings were specified assuming 10-12% timber; oversized mortises and glued joints that were tight at assembly open as the timber dries. These interact because the defect is not a single bad batch but a process control failure: without adequate kiln capacity the workshop cannot bring stock to specification before machining, so every downstream stage (machining tolerance, gluing, finishing) inherits the problem. The withheld payment and opening joints are symptoms, not separate faults. A judgement answer should also note the sociological/commercial dimension: the firm's market position depends on a quality and provenance claim that the cheaper softwood substitution would undermine, so the technical fix must be solved within the hardwood strategy rather than by abandoning it.
2. Recommend and justify a course of action for the next ten weeks, addressing both contracts and the longer-term process.

A defensible plan separates the short-term delivery problem from the process fix.
Short term (weeks 1-10):
- Buy in kiln-dried stock at 10-12% from an alternative supplier for the two school contracts, even at higher cost, and verify each batch with a moisture meter on receipt (record readings). Accept reduced margin on these contracts to protect the relationship and recover the withheld $12,000.
- Rectify the failed job first and document the fix, since the client's trust is the firm's main asset.
- Re-sequence production so the existing kiln runs continuously on the highest-value stock rather than being used opportunistically.
Medium term:
- Introduce incoming-goods inspection with a documented moisture specification and a reject/return clause in supplier agreements.
- Either outsource kiln drying to a local mill or schedule drying into the production lead time (build a drying buffer into quotes) rather than assuming dry stock is available.
- Train staff to record moisture readings at machining and pre-finishing so drift is caught early.
Justification: this protects the contracts and reputation now while fixing the root cause (no incoming inspection, no drying buffer, insufficient capacity) rather than masking it. Rejecting the hardwood strategy outright would destroy the firm's differentiation; the cheaper softwood is a false economy because it does not solve the moisture control problem and damages the brand.
