What is Productivity?
At its core, it measures how efficiently inputs are converted into outputs. In simpler terms, it’s about getting more bang for your buck. For instance, if a factory produces 100 widgets using 50 hours of labour, and later manages to produce the same 100 widgets using only 40 hours, its efficiency has increased. This improvement means the factory is making better use of its resources to achieve the same output.
Expecting Productivity Improvements from Suppliers
As a buyer, it’s reasonable to expect your suppliers to continually seek ways to boost their output. This expectation isn’t about pushing them to work harder but encouraging them to work smarter. Improvements can stem from various initiatives:
- Process Optimization: Streamlining operations to eliminate waste and reduce inefficiencies.
- Technological Upgrades: Implementing advanced machinery or software to enhance production capabilities.
- Training and Development: Investing in employee skills to improve performance and reduce errors.
When suppliers enhance their productivity, it often leads to cost savings, better quality products, and more reliable delivery schedules—all of which benefit you as the buyer.
Incorporating Productivity into Yearly Negotiations
Annual negotiations with suppliers are prime opportunities to discuss productivity improvements. Here’s how you can approach it:
- Set Clear Expectations: Clearly communicate your desire for continuous improvement. This could be in the form of cost reductions, quality enhancements, or faster delivery times.
- Collaborative Goal Setting: Work together to establish realistic productivity targets. This collaborative approach fosters a sense of partnership and shared responsibility.
- Incentivize Improvements: Consider structuring contracts that reward suppliers for achieving specific productivity milestones. This could be through bonuses or extended contract terms.
- Regular Reviews: Schedule periodic meetings to assess progress towards productivity goals and address any challenges that arise.
By embedding discussions about this topic into your negotiations, you signal to suppliers that you value continuous improvement and are committed to mutual success.
The Learning Curve: A Pathway to Efficiency
The “learning curve” is a concept that illustrates how repetition of a task leads to improved performance and efficiency over time. In manufacturing, for example, as workers become more familiar with a process, they can perform it faster and with fewer errors. This phenomenon is also known as “experience curve effects.”
Understanding the learning curve can be advantageous in procurement:
- Cost Projections: Recognize that new processes or products might have higher initial costs, which are expected to decrease as efficiency improves over time.
- Supplier Assessment: Evaluate how quickly a supplier can move down the learning curve, which can be indicative of their commitment to continuous improvement.
- Negotiation Leverage: Use anticipated efficiency gains as a basis for negotiating future cost reductions.
By considering the learning curve, you can make more informed decisions and set realistic expectations with your suppliers.
Batch Sizes and Their Impact on Productivity
Batch size refers to the quantity of units produced in one production run. The size of these batches can significantly influence productivity:
- Large Batch Sizes:
- Advantages: Economies of scale can reduce the cost per unit, and setup times are spread over a larger number of units.
- Disadvantages: Increased inventory holding costs and potential for overproduction.
- Small Batch Sizes:
- Advantages: Greater flexibility to respond to demand changes, reduced inventory costs, and quicker identification of defects.
- Disadvantages: More frequent setups can lead to higher setup costs per unit.
As a buyer, understanding the implications of batch sizes can help you work with suppliers to determine the most efficient production strategies. For instance, if you can provide more accurate demand forecasts, suppliers might be able to optimise batch sizes to enhance their efficiency.
Can a buyer expect yearly productivity improvements?
Yes, while the percentage of expected yearly productivity improvement varies by industry, company, and specific processes, a general benchmark often cited in procurement and manufacturing is 3% to 7% per year.
This expectation is based on several factors:
1. Industry Standards
- Manufacturing & Industrial Sectors: Lean manufacturing principles and automation can drive annual productivity gains of 3% to 5%.
- Tech & Software Development: Productivity improvements tend to be higher, often reaching 5% to 10%, due to automation and rapid technological advancements.
- Logistics & Supply Chain: Process optimizations and digitalization usually lead to 2% to 5% gains.
2. The Learning Curve Effect
- The learning curve suggests that with every doubling of cumulative production, unit costs can decline by 10% to 30%.
- This means that in the early stages of a supplier relationship or product introduction, productivity gains could be higher than the long-term steady-state improvement.
3. Procurement and Supplier Agreements
- Many supplier contracts include cost reduction clauses linked to productivity improvements, typically ranging from 3% to 5% per year.
- Suppliers often factor in automation, process optimization, and economies of scale to meet these expectations.
- External factors like inflation, commodity pricing, etc also influences the end price.
4. Industry-Specific Examples
- Automotive Industry: Productivity improvement targets are typically 4% to 6% per year due to continuous process optimizations.
- Electronics & Semiconductors: Expect 5% to 10% due to rapid technological advancements and scale efficiencies.
- Consumer Goods: A more conservative range of 2% to 4% is common due to demand variability.
How This Can Be Used in Yearly Negotiations
- Set clear productivity targets based on industry benchmarks.
- Tie pricing reductions to agreed-upon improvement rates (e.g., a 3% annual cost reduction).
- Monitor and review progress periodically to ensure that efficiency gains translate into tangible benefits.
Structuring Productivity Expectations in Procurement Contracts
When incorporating productivity improvement expectations into supplier contracts, it’s essential to ensure clarity, fairness, and enforceability. Here’s a structured approach to help you achieve this:
1. Define Clear Productivity Improvement Targets
Set specific, measurable expectations based on industry benchmarks. Common targets include:
- Annual cost reductions of 3% to 5%, tied to supplier productivity gains.
- Efficiency improvements, such as reduced lead times or defect rates.
- Technology adoption, like automation or digital process improvements.
Example Contract Clause:
“Supplier agrees to implement continuous process improvements that result in a minimum cost reduction of 4% per annum, measured against the previous year’s baseline.”
2. Link Cost Reduction to Productivity Gains
Ensure that productivity improvements lead to cost reductions that benefit both parties. Consider defining how savings are shared.
📌 Cost-Reduction Formula:
“The unit price shall be reduced annually by 3% to reflect the supplier’s efficiency gains, achieved through process optimization, automation, and supply chain improvements.”
Alternatively, a shared-savings model can incentivize suppliers:
“Cost savings beyond 5% per year shall be shared equally between Buyer and Supplier, ensuring mutual benefit.”
3. Build in Learning Curve Benefits
Leverage the learning curve effect (cost reductions from increased experience) in pricing negotiations.
📌 Example Approach:
- For new products or processes, agree to an initial higher price, but demand gradual reductions as the supplier improves efficiency.
- Stair-step pricing: “For every 20% increase in order volume, Supplier shall reduce unit costs by 5%.”
4. Adjust Pricing Based on Volume & Batch Size
Batch size and production volume significantly impact productivity. You can:
- Negotiate lower prices for larger, consistent order volumes.
- Include tiered pricing that rewards increased purchase commitments.
📌 Example Clause:
“For order volumes exceeding 10,000 units per quarter, unit pricing shall be reduced by 4% to reflect economies of scale and improved production efficiency.”
5. Implement a Performance Monitoring Mechanism
Ensure transparency and accountability by setting up regular performance reviews with suppliers.
📌 Monitoring Structure:
- Quarterly or biannual performance reviews to assess cost and efficiency improvements.
- Require documentation of process optimizations, automation, or waste reduction initiatives.
- Include an audit clause: “Buyer reserves the right to audit Supplier’s production process annually to verify cost and efficiency improvements.”
6. Use Incentives & Penalties for Compliance
Encourage suppliers to meet productivity targets with:
✅ Incentives:
- Longer contract terms for meeting improvement goals.
- Bonus payments for exceeding cost-saving targets.
🚨 Penalties:
- A failure-to-improve clause that triggers renegotiations or alternative sourcing.
- Price freezes or supplier replacement options for underperformance.
📌 Example Clause:
“Failure to achieve the agreed-upon 3% cost reduction shall result in price renegotiation or a competitive rebid process.”
Final Thoughts: Collaborate, Don’t Just Demand
While it’s important to push for productivity gains, the best results come from collaborative efforts. Instead of solely demanding cost reductions, work with suppliers on:
Training programs that upskill workers and reduce human error.
Joint improvement initiatives (e.g., lean manufacturing, automation).
Data-sharing agreements to track and enhance efficiency.
