Re: [SPAM] MRP related suggestions

Here my comments to these great suggestions.

1. BOM Management: It should be necessary to separate the BOM changes due to a revision and the one due to a mistake. Therefore, a strict revision control should only be an option that a user can set for his BOMs.

2. Change management is a great tool and it should be possible to decide to activate it or not.

3. Consumption based replenishment is not the equivalent to kanban. So we can think about a consumption based replenishment that would work without any Kanban card, only based on the minimum level of stock of a specific product (that may trigger either a purchase requisition or a production requisition) and also have a kanban set-up, that is usually used for internal production.

4. VMI: I believe it's a great idea to give real time access to the actual stock level. But, I doubt, that the suppliers will agree to having to monitor the stocks themselves, as they already give the stock without prior payment. Further, it is a very high risk for a company to not monitor her replenishment herself. It is best practice to still have the company giving the ok to a replenishment proposal that is created automatically.

5. QMS should be another project. I believe as a shortcut for a few companies, an in-process control could solve many requirements, just by having a list of operations that are defined as QC operations and that would require to be validated by certain users with authorisation, and to which a quality check procedure can be attached.

Hi. That is a great list of MRP requirements. There are a number of ideas I would like to air:

BOM management - allow the user to implement strict revision control i.e. Any change to a BOM or it's children force an up revision of the BOM, this brings about great traceability on product builds but at the cost of additional maintenance and administration. The alternative is to allow the user to modify BOM's and choose when to change the revision.

Engineering BOM - Allow the user to create an Engineering BOM from which they can derive a manufacturing BOM. Engineering BOM will reflect the product design whereas the Manufactuing BOM will be structured to reflect the build and assembly process I.e. Design may have a subassembly with all the child components identified (part numbers, drawing numbers etc.) and Manufactuing may purchase the subassembly.

Engineering Change management - allow the user to operate a change management process I.e. Log a change, review a change, change approval, change implementation. Experience has taught me that a badly managed change process will result in shortages, excess and obsolete inventory, incorrect production builds, slow adoption of improvements.

Consumption based replenishment - allow the user to set up a kanban system. Kanban card scanned sends request to nominated supplier to deliver more product - perhaps this is more on an inventory/WMS functionality but can be key in keeping production fed with material.

Vendor managed inventory (VMI) - allow the user to set up a supplier portal to give nominated suppliers visibility of stock in specific locations. Supplier monitors inventory and replenish stock when it reaches an agreed level - again this is perhaps more of an inventory/WMS functionality but can be key in keeping production fed with material.

Production asset tracking  - allow the user to track production assets such as tooling, jigs, fixtures, gauges and define calibration dates, checks, maintenance dates, ownership etc. perhaps this is a part of the maintenance (of a machine) section.

Quality control - allow the user to log and control non conformances - part of the QC functionality 

Quality management system (QMS) - allow the user to create and manage a QMS based on a standard such as ISO9001, including document management for drawings, specifications, supplier data sheets, work instructions, procedures et al. I know this is a big area but how many manufacturers don't need to comply with some form of quality standard. This would be a major feature of odoo to many in the medical device, aerospace and defence sectors to name a couple that have specific ISO requirements.

Just a few thoughts for now!
