Planners don’t just react. They anticipate.

 



In the world of manufacturing and supply chain management, effective planning is crucial for maintaining efficiency and meeting customer demands. Reviewing part planning parameters is a vital step in optimizing Material Requirements Planning (MRP) and Production Requirements Planning (PRP). By ensuring that key master files are accurately managed and regularly reviewed, organizations can avoid common pitfalls and enhance their operational performance.

Key Part Planning Parameters

Part planning parameters are essential metrics that guide inventory management, production scheduling, and supplier interactions. Here are some of the critical parameters that planners should focus on:

  • Lead Time Days: The time required to procure or produce a part. Accurate lead times help in scheduling and reducing stockouts.
  • Minimum Inventory Quantity: The lowest acceptable level of inventory before reordering. This parameter prevents stockouts and ensures production continuity.
  • Unit: The measurement unit for inventory (e.g., pieces, kilograms). Consistency in units is vital for accurate inventory tracking.
  • Maximum Inventory Quantity: The upper limit of inventory to avoid overstocking and associated carrying costs.
  • Default Stock Location: The designated storage area for parts, which aids in efficient inventory management.
  • MRP Demand Level: The forecasted demand for a part, which influences production and purchasing decisions.
  • Standard Job Quantity: The typical quantity produced in a single job, impacting production scheduling.
  • Standard Order Quantity: The usual quantity ordered from suppliers, which can affect lead times and inventory levels.
  • Minimum Order Quantity: The smallest quantity that can be ordered from a supplier, crucial for managing supplier relationships.
  • Minimum Job Quantity: The least amount that can be produced in a job, which can affect production efficiency.
  • Finished Part Buffer: The safety stock level for finished goods, ensuring availability for customer orders.
  • Job Consolidation Window: The timeframe for consolidating jobs, which can optimize production runs.
  • Planning Group: A classification for parts that share similar planning characteristics, aiding in streamlined management.
  • Part Shelf Life: The duration a part can be stored before it becomes unusable, critical for perishable items.
  • Part Shelf Life Unit: The unit of measurement for shelf life (e.g., days, months).
  • Supplier Shelf Life Unit: The shelf life measurement for supplier-provided parts.
  • Supplier Shelf Life: The duration a supplier part can be stored before it becomes unusable.
  • Planner: The individual responsible for managing the part's planning parameters.
  • Engineer (1-3): The engineering contact for the part, ensuring technical specifications are met.
  • Supplier Name: The name of the supplier providing the part, essential for procurement processes.
  • Supplier Lead Time: The time it takes for a supplier to deliver parts, influencing inventory levels.
  • Supplier Minimum Quantity: The minimum order quantity required by the supplier.
  • Supplier Transit Time: The time taken for parts to be transported from the supplier to the manufacturer.
  • Supplier Business Percentage: The percentage of business allocated to a supplier, which can affect negotiations and relationships.

Common Issues Related to Key Master Files

Failing to manage or review key master files can lead to several common issues that negatively impact MRP and PRP. Here are some examples:

  • Inaccurate Lead Times: If lead times are not regularly updated, planners may order too late, resulting in stockouts and production delays.
  • Incorrect Minimum Inventory Levels: Setting minimum inventory quantities too low can lead to frequent stockouts, while setting them too high can increase carrying costs.
  • Mismanaged Shelf Life: Not tracking part shelf life accurately can result in expired materials being used in production, leading to quality issues and waste.
  • Supplier Relationship Problems: Failing to review supplier lead times and minimum quantities can strain relationships and lead to missed deliveries or excess inventory.
  • Inefficient Job Scheduling: Without accurate standard job and order quantities, production schedules may become inefficient, leading to increased costs and delays.
  • Poor Inventory Visibility: If default stock locations are not properly managed, it can lead to confusion and inefficiencies in inventory retrieval and management.

Conclusion

Regularly reviewing part planning parameters is essential for optimizing MRP and PRP. By addressing common issues related to key master files, organizations can enhance their operational efficiency, reduce costs, and improve customer satisfaction. Implementing a systematic approach to managing these parameters will ensure that manufacturing processes run smoothly and effectively, ultimately leading to better business outcome

Automate the schedule of AR invoices and statements using the Plex ERP Document Delivery module.

Image
Manual invoicing and emailing of customer statements can be a time-consuming and resource-intensive process. According to a study by Skynova, most businesses handle up to 500 invoices each month and spend at least five days processing invoices .  The same study also found that 57% of invoice data is entered manually and 49% of businesses require two to three people to approve an invoice. These manual processes can lead to delays in payment and inefficiencies in the accounting process. Invoicing automation can help reduce the time and resources spent on manual invoicing. According to Skynova,Only about half of invoices (52%) are received electronically. The rest are paper invoices that need to be physically sorted, entered, and filed, adding additional steps to the invoice process. The following module in Plex manufacturing allows automatically delivery AR invoices and customer statements via email which can lead to improvement and reduce of the waste of resources associated by manu...
