Why do we draw a basic design and a detailed design

In order to be able to fully evaluate the chosen direction we complete a basic design. We draw schematics, diagrams and/or layouts that help us bridge the gap between concept and a real-world, manufacturable solution. Our experience with manufacturing is invaluable in this phase, our engineers are able to evaluate the impact of certain choices on production processes and costs and the team can incorporate the consequences in the design. Finalizing a design also includes matching tolerances, material requirements, sourcing and matching the various parts. Again, manufacturability is a key concern, our experience helps us discover risks and challenges before applications or products are being produced. Such challenges might include changing assembly conditions or requirements, the impact of production processes on the interoperability of parts and even the preparation of raw materials.
