Sapphire Textile Mills Limited: Refined Costing Custom Case Solution & Analysis

Evidence Brief

Financial Metrics

Revenue Growth: STML maintains a significant share in the Pakistani textile export market, yet net margins have compressed to less than 5 percent due to global competition and rising input costs.
Overhead Allocation: Current systems utilize a single plant-wide overhead rate based on direct labor hours or machine hours, regardless of product complexity.
Energy Costs: Power and fuel expenses represent approximately 15 to 20 percent of total manufacturing costs, varying by mill efficiency (Source: Exhibit 4).
Product Mix: The company produces a wide range of yarn counts and fabric constructions, with high-volume commodities and low-volume specialized orders sharing the same cost pool.

Operational Facts

Process Diversity: Operations include spinning, weaving, and finishing. Spinning is capital intensive; finishing is utility and chemical intensive.
Capacity Utilization: Mills operate 24 hours a day in three shifts. Idle time during product changeovers in weaving is not currently tracked as a distinct cost driver.
Geography: Primary manufacturing clusters are located in Punjab, Pakistan, facing intermittent power supply and fluctuating raw cotton prices.
Headcount: Labor intensive finishing departments require more supervision than automated spinning units, yet overhead is applied uniformly.

Stakeholder Positions

CFO: Concerned that current costing masks losses on complex, small-batch orders while overpricing high-volume commodity products.
Production Managers: Resist detailed time-tracking, fearing it will increase administrative burden and highlight operational inefficiencies.
Sales Team: Require accurate floor prices to remain competitive in the post-quota international market without sacrificing margin.

Information Gaps

Specific electricity consumption per spindle hour for different yarn counts is not recorded.
Waste percentages for specialized fabric runs are estimated rather than measured.
The exact cost of downtime during machine maintenance is not allocated to specific product lines.

Strategic Analysis

Core Strategic Question

STML must determine how to transition from a volume-based costing model to a refined system that accurately reflects the resource consumption of diverse product lines to prevent margin erosion.

Structural Analysis

Value Chain Analysis: The primary cost distortions occur in the weaving and finishing stages. Traditional costing assigns overhead based on machine hours, but finishing involves complex chemical applications and varied energy intensities that machine hours do not capture. This leads to under-costing complex products and over-costing simple ones.

Porters Five Forces: Rivalry is intense. Low-cost competitors from Vietnam and Bangladesh utilize aggressive pricing. STML cannot compete on price without knowing its true floor. Buyer power is high; international retailers demand transparency and competitive bidding, leaving no room for pricing errors.

Strategic Options

Option 1: Full Activity-Based Costing (ABC) Implementation. Identify all activities, assign costs to pools, and use multiple drivers. Rationale: Provides the highest accuracy. Trade-offs: High administrative cost and potential for data overload.

Option 2: Time-Driven Activity-Based Costing (TDABC) for High-Complexity Units. Focus only on weaving and finishing where the product mix is most diverse. Rationale: Captures the cost of complexity without the burden of a full-plant overhaul. Trade-offs: May create internal accounting inconsistencies between departments.

Option 3: Status Quo with Revised Overhead Rates. Maintain the current system but update the blanket rates more frequently. Rationale: Least disruptive. Trade-offs: Fails to solve the fundamental problem of cross-subsidization between products. This option is rejected as it leads to continued loss of market share in profitable segments.

Preliminary Recommendation

STML should adopt Option 2. Implementing TDABC in the finishing and weaving divisions allows the firm to identify which specialized orders are actually destroying value. This targeted approach minimizes organizational resistance while providing the necessary data for strategic pricing.

Implementation Roadmap

Critical Path

Month 1: Define resource units and calculate the cost per minute of capacity for the finishing department.
Month 2: Map activities for top 20 percent of product variants by volume and top 20 percent by complexity.
Month 3: Execute a pilot run comparing TDABC results against traditional costing for a single quarter.
Month 4: Adjust pricing for low-margin, high-complexity products based on pilot findings.

Key Constraints

Data Integrity: The accuracy of the new system depends on the shop floor staff recording setup times and chemical usage precisely.
IT Infrastructure: Current ERP modules may require customization to handle multiple cost drivers and time-based capacity equations.

Risk-Adjusted Implementation Strategy

The transition will follow a phased rollout. To mitigate resistance, bonuses for production managers will be decoupled from cost-reduction targets during the first six months of data collection. A contingency fund of 15 percent of the project budget is allocated for external IT consultants to handle ERP integration issues.

Executive Review and BLUF

BLUF

STML is currently flying blind. The reliance on a single overhead rate is causing the company to win unprofitable business while losing high-volume contracts due to overpricing. Management must implement Time-Driven Activity-Based Costing in the finishing and weaving units immediately. This is not an accounting exercise; it is a survival requirement in a low-margin global market. The goal is to identify and exit or re-price the bottom 15 percent of loss-making products within two quarters.

Dangerous Assumption

The most dangerous premise is that the sales team can successfully raise prices on complex products once costs are known. In a commoditized textile market, prices are often dictated by the buyer, not the cost of the seller. Accurate costing may lead to the realization that STML must exit certain segments entirely rather than simply raising prices.

Unaddressed Risks

Market Price Caps: If the market will not bear the corrected price, the investment in a refined costing system yields only the knowledge of a loss, not a path to profit. Probability: High. Consequence: Strategic exit required.
Data Manipulation: Middle management may under-report time spent on complex tasks to appear more efficient under the new metrics. Probability: Medium. Consequence: Inaccurate strategic decisions.

Unconsidered Alternative

The analysis focused on costing existing processes. The team should consider a shift toward an Original Design Manufacturer (ODM) model. Instead of refining the cost of basic manufacturing, STML could invest in design capabilities to move into higher-margin categories where the precision of costing is less critical than the value of the brand and design.
