ManEx Case Solution
Regardless of the method selected, ManEx has the tools to document and control assembly changes and revisions.
- ECO Module - The ECO module allows users to document the source (internal or customer), the purpose, the details, and the impact of the change. The module can apply the changes to new and existing jobs, and ensure that production is aware of the change and is using the latest information. This module works well with any of the three approaches.
- Effectivity/Obsolete Dates - The Effectivity and Obsolete Dates allow users to document in the Bill of Material when parts were added and/or removed. This automatically applies the changes to existing orders even if the assembly revision doesn't change. This method is most effective when using the customer's revision as the internal revision, but can be used for any of the three approaches.
- BoM History - If the effectivity and obsolete dates are used, then it is possible to check the specific parts list at any given date using the BoM history in the Integrated Bill of Material & AVL module. This method is most effective when using the customer's revision as the internal revision, but can be used for any of the three approaches.
- BoM Copy - To simplify changing a Bill of Material, while maintaining the original version of the assembly, users can copy the parts list into a new assembly and make changes as needed. This tool works well with either of the three approaches, but is only needed in the absence of the ECO module.
- Relation to customer assembly and revision - ManEx allows users to connect the customer part number and revision with the internal part number and revision. This simplifies communication by allowing users to find the correct internal part number and revision associated with the customer's assembly and revision even if the part numbers and revisions do not match. This works well with any of the three approaches.
- Separate assembly number and revision fields - ManEx uses separate assembly and revision fields making it easier to group all revisions of the same assembly and verify that the correct version is selected for production. This works with any of the three approaches.
NE Company decided to use the combination approach and utilized the tools in ManEx to control and manage this process. All new assembly revisions are initially set to match the customer's assembly revision. Any changes made internally or by the customer result in either a part number or revision change even if the customer doesn't update their own revision.
This recently allowed NE Company to prevent a mistake. The customer revised their AVL on assembly PCA-8596 Rev T, but didn't update their revision, NE Company created assembly 910-PCA-8596 Rev T[1]. When they received the order for PCA-8596 Rev T, they were able to ensure that purchasing order only currently approved components.
