Easy Plan overview
What is Process Planning for ETO?
Process Planning for ETO is used to do process planning and create work instructions for the shop floor. It lets you author the plan and the documentation for the manufacturing bill of material (MBOM) assemblies. It also lets you write instructions and assign visual illustrations to those processes and operations. Process Planning for ETO is designed for engineer-to-order (ETO) domains, with a focus on the aerospace and defense industries.
Process Planning for ETO uses structures that are contained in an existing or just-created work package:
Product structures that consist of parts that make up the physical elements needed to assemble the product.
Process structures that contain processes and operations that define the assembly process.
Unlike the Process Planning for BTO/BTS/CTO solution, which is based on the plant structure, a process structure for Process Planning for ETO is based on the MBOM structure and used to document the instructions for each assembly.
Once the work package is defined, you can perform the following tasks:
Author the work instructions for an MBOM assembly, including texts and visuals, which generates a process plan.
Author and detail the generated process plan.
