Our Systems Development Process was created to manage the development of complex microsystem products in a swift but methodical manner. Treehouse uses a disciplined approach to engineering that balances modeling and simulation with experimental evaluations. This process ensures that all customer, product and regulatory needs are properly considered and business factors are accurately calculated. The phases of this process are:
Phase #1: Feasibility. In this phase, working closely with the customer, we evaluate the suitability of various technical solutions and compare their suitability for meeting customer needs. Risk analysis, reliability and qualification plans, short-loop experiments and development and business plans are typical deliverables.
Phase #2: Design and Prototype. Prototype fabrication is used to further validate the targeted solution and they help allow you to evaluate how the product can fit into your overall system. These early prototypes can be used in conjunction with FMEA tools to reduce overall program risk. Subsequent versions move the design towards production by focusing on validating function, reliability, manufacturability and cost. In this phase, product designs are completed and initial prototype devices are fabricated within the appropriate regulatory environment. Design and engineering activities focus on circuits, components, packages, firmware and software as well as system-level interconnect. Key suppliers are evaluated and selected, and process development activities commence with product-specific drawings, layouts, and the creation of preliminary production documentation. Tooling, unique equipment, and fixtures are specified and procured, as required. Prototype devices are fabricated and tested, and designs are verified through initial testing.
Phase #3: Development, Qualification and Pre-Production. As the final step before production, the device is subjected to the appropriate qualification process that can include supplier qualification, environmental and life testing. In this phase, larger numbers of devices are assembled and tested and a development feedback loop is used to make design, process and material changes, as needed. All production processes are statistically verified for their ability to meet the production criteria within the appropriate regulatory environment. Initial process capability data is generated during this phase and control and reaction plans are completed. Next is process validation, and the product is subjected to the entire reliability test plan. Appropriate documentation is maintained throughout the development effort to ensure a seamless transition to production. The deliverable from this phase is a qualified product that is ready for volume production.
Phase #4: Production. This is the phase in which manufacturing and business plans are completed and formal production begins, according to the volume ramp plan. Additional capacity is brought on line as needed, and continuous quality improvements, cost reductions and yield enhancements are emphasized during this on-going production phase. Qualified suppliers are managed closely to ensure overall program objectives continue to be met.
