Quel est le processus optimal pour fabriquer un produit sur mesure ?

Keeping the engineering value in control, quality, and optimization out put in control, process checks input resource audit, transit awareness etc..

Define the scope of a project involving a customized product is always tricky. I never experienced a situation were the specs were totally clear or sometimes even all the main features. At the very end this will impact the project management. One possible strategy is to properly use the kano model and when possible discuss with a potential customers as much as possible. At the same time you must live with the fact reality does not cooperate most of the times, so your risks and change management scheme must be robust and agreed with the project stakeholders. An hybrid agile- approach may be also a possible strategy when costs and impact on the timeline are well communicated. Finally when possible a modular approach.

If you are looking to minimise disruption in getting a product out to customers, applying Design for Manufacture (DFM) principles is essential. Eliminate unnecessary problems, time consuming and costly adjustments by considering restrictions of the intended manufacture process during the design and prototyping phase, not at production.

Product Verification should be step 3. Execute this step after implementing feedback from consumers and test data from the prior iteration. Exit the iterative design process once you arrive at a design that satisfies the intended target market and meets all functional requirements and cost targets. Only after forging a robust design should you move forward with the design and execution of the manufacturing process and then finally deliver.

Although it is a customized product, and therefore very specific to the request of a client or "special" client profiles, we must not forget the issue of communication, advertising, increasing the aura of exclusivity, etc... that It makes the product even more differentiating.

There should be someone who can visualise the process (like shaping, milling, turning, drilling, EDM, etc. to complete the job. Then plan them. And allocate them to the right people. You repeat it and iterate it. That is what is called process. By the way you can use good digital tools to organise the multi disciplinary operations to make a custom parts, and route them properly with an estimated time. Monitor or track the time. If you find deviation, adjust it in your next execution. I suggest you can try Getala to get this done. Please remember it’s just a digital tool with which helps a company to become process oriented. We cannot make everything automatic. Of course, future is 3d printed parts. Design it and print it.

The reality is that it is a waste of time to start out trying to create an optimum process. You will hold up getting 1st product out the door & into the hands of your Customers. The most successful processes I've seen first create processes that were not perfect but were good enough to get production started (balanced time, $$, quality). If product demand is there, then go back and optimize. That does not mean producing crap product at any point in time. It just means being clever at how you do it and planning on it evolving. Any business person worth their salt will understand that manufacturing costs will most likely not meet expectations right out of the chute. But they will support you if you've contributed to proving product demand.
