A comparative table of the advantages and disadvantages of Lean methodologies is presented below: 

Performance gap analysis 

Performance gap analysis is another method for improving production planning. It aims to identify the differences between set targets and actual results, and then implement corrective actions. The key steps in this analysis are  

1. Data collection: gather information on the company's key performance indicators (KPIs).  
2. Data analysis: compare actual results with targets to identify gaps.  
3. Identify causes: determine the factors that have contributed to discrepancies.  
4. Corrective action: develop and implement plans to eliminate or reduce variances.  

An example of the application of performance gap analysis is the OEE (Overall Equipment Effectiveness) matrix, which assesses a company's overall efficiency by analyzing three major components: availability, performance and quality.

By implementing Lean methodologies and performance gap analysis, companies can improve their production planning processes and achieve sustainable growth. 

Key Performance Indicators (KPI)  

Key Performance Indicators (KPIs) are essential for assessing the efficiency and cost-effectiveness of the production planning process. They provide an overview of the progress made and enable improvements to be made based on the results obtained.  

KPI monitoring  

KPIs need to be monitored regularly to ensure optimal production control. Here are some important KPIs to consider:  

1. Synthetic yield rate (SRR): Measures overall equipment efficiency, taking into account availability, performance and quality.  
2. Production lead time: Total time required to produce an item or set of items, from order to delivery.  
3. Defect rate: Percentage of defective products in relation to the total number of products manufactured.  
4. Customer satisfaction rate : Percentage of customers satisfied with the products delivered and the level of service provided.  
5. Production costs: Total costs associated with manufacturing a product, including labor, materials and equipment.  

It is essential to track these KPIs using appropriate management and monitoring tools, such as dashboards and reporting systems. 

KPI-based improvement  

Once the KPIs have been identified and tracked, any necessary adjustments can be made to improve production planning performance. The following measures can be taken based on KPI results:  

• Increase equipment availability: If the OEE is low, steps should be taken to reduce downtime and improve equipment availability.  
• Reduce production lead times: If production lead times are long, efforts should be made to optimize processes and reduce the time needed to produce an item.  
• Minimize defect rates: If defect rates are high, corrective action must be taken to reduce errors and improve product quality.  
• Improve customer satisfaction: If the customer satisfaction rate is low, efforts must be made to improve customer service and listen to customer needs.  
• Reduce production costs: If production costs are high, opportunities can be identified to reduce labor, material and equipment costs.  

In summary, KPIs play a crucial role in production planning management. They enable performance to be constantly monitored and improved in line with set objectives.
