Current Financial Performance:
Supplier Base: FlexTech sources components from 47 suppliers across three regions:
| Region | % of Spend | Lead Time | Shipping Cost | Quality Score |
|---|---|---|---|---|
| Asia (China, Taiwan) | 62% | 45 days | $12-18/kg | 4.2% defect rate |
| Eastern Europe | 23% | 28 days | $8-11/kg | 2.8% defect rate |
| North America | 15% | 12 days | $3-5/kg | 1.5% defect rate |
Logistics & Transportation:
Issue: 62% of component spend sourced from Asia with 45-day average lead times. Recent port congestion has extended this to 52-58 days for 35% of shipments.
Impact:
Annual Cost Impact: $23M (working capital opportunity cost @ 12% + expedited freight + lost margin on cancelled orders)
Issue: Surface mount technology (SMT) line operating at 94% capacity utilization. Current facility has limited space for expansion.
Impact:
Annual Cost Impact: $7.8M (lost revenue opportunity + overtime premium)
Issue: 4.2% defect rate on Asian-sourced components (vs. 1.5% North American benchmark). Incoming inspection catches 60% of defects; remaining 40% discovered in production.
Impact:
Annual Cost Impact: $7.2M (rework + scrap + customer returns)

Identify and quantify the primary supply chain bottlenecks
Effective bottleneck analysis requires identifying constraints that limit overall system throughput. Use the materials to:
FlexTech's 45-day average lead time from Asian suppliers (62% of component spend) creates a cascading operational crisis. First, it forces FlexTech to maintain 40% higher safety stock levels, tying up $8.2M in working capital that could otherwise be invested in growth. Second, when customer orders come in, the long lead time means FlexTech frequently resorts to expedited air freight at 4x the cost of ocean shipping, driving expedited freight costs to $2.8M annually (up 250% from two years ago). Third, even with these measures, on-time delivery has plummeted to just 32% for key customers, causing $12M in cancelled orders as customers switch to more reliable suppliers. The combination of higher inventory carrying costs, premium freight, and lost revenue creates a $23M annual impact that is directly eroding FlexTech's competitive position.
Extended lead times are bad for FlexTech because they cause delays. When suppliers take too long to deliver parts, it creates problems in production. This leads to higher costs and unhappy customers. The company needs to find ways to reduce lead times to improve efficiency.
Why this fails: No specific metrics, no quantification of impact, generic statements that could apply to any company.
Analyze why these bottlenecks exist and their interconnected impacts
Moving beyond symptoms to underlying causes:
FlexTech's 94% capacity utilization creates a brittle system with no buffer to absorb variability. When quality defects occur (4.2% rate), production must stop to rework faulty units, consuming 8% of manufacturing time. With virtually no spare capacity, this rework forces costly overtime ($1.8M annually, 18% of direct labor) and delays other orders. The situation is compounded by 45-day lead times from Asian suppliers—when a batch arrives with defects, there's no time to reorder without disrupting the entire production schedule, forcing expensive expedited air freight. Additionally, equipment downtime (6.2% unplanned) in an overutilized facility cascades into missed customer commitments. The lack of capacity buffer means FlexTech must turn down $6M in high-margin rush orders annually, even as they struggle to fulfill existing commitments. This creates a vicious cycle: capacity constraints prevent accepting new business, which limits revenue growth needed to invest in additional capacity, while quality issues consume the limited capacity that exists.
Evaluate improvement options and select optimal strategy
Three improvement strategies are detailed in materials. Evaluate each based on:
FlexTech should prioritize the Integrated Supplier Quality Program first, despite Supplier Diversification addressing the primary bottleneck more directly. The quality program delivers exceptional ROI of 971% with only $1.4M investment and an extraordinarily fast 3-month payback period. This low-risk, high-return initiative immediately reduces the defect rate from 4.2% to 1.8%, generating $4.2M in annual savings from eliminated rework, scrap, and customer returns, plus an additional $800K from reduced production disruptions. Critically, this strategy can be implemented quickly without major capital expenditure or operational disruption—FlexTech can deploy 3 resident quality engineers to top Asian suppliers within 60 days. The rapid payback means FlexTech will generate $5M in savings within the first year to help fund the more capital-intensive strategies. Furthermore, improving supplier quality creates a more stable foundation for the subsequent near-shoring strategy (which requires $10.35M investment), since FlexTech will be negotiating with new suppliers from a position of better quality management capability. While the quality program alone won't solve the 45-day lead time issue, it represents a quick win that builds momentum, generates cash, and de-risks larger initiatives.
Build phased implementation plan with measurable milestones
The materials provide a 4-phase, 24-month implementation roadmap. Your task:
FlexTech's first 12 months should follow a carefully sequenced two-phase approach. Phase 1 (Months 1-6) focuses on quick wins with minimal capital: launch the supplier quality program by deploying 3 resident quality engineers to top Asian suppliers, qualify 2 North American alternative suppliers for the top 10 component categories, and implement enhanced incoming inspection protocols with upgraded equipment. This phase requires minimal investment ($700K) but delivers immediate impact—reducing the defect rate from 4.2% to 3.0%, generating $2.1M in annualized savings from reduced rework and scrap, and beginning the supplier diversification process. The 3-month payback on the quality program generates cash flow to fund subsequent phases. Phase 2 (Months 7-12) deploys the capital-intensive initiatives: complete installation and commissioning of the second SMT line with automated optical inspection ($4.5M investment), shift 15% of Asian component spend to the newly qualified North American suppliers (reducing average lead time from 45 to 38 days), and install the AGV material handling system ($800K). This phase delivers $5.8M in annualized savings through multiple mechanisms: capacity utilization drops from 94% to 68% (eliminating the need to turn down $3M in rush orders), overtime costs decrease by 50% ($900K savings), and the combination of better quality (2.2% defect rate) and shorter lead times enables a reduction in expedited freight usage ($1.2M savings). By month 12, FlexTech achieves 87% on-time delivery (up from 68%), positioning the company to pursue Phase 3's full near-shoring transition.
