Stage Gate Development
HTG uses a 4 step product design strategy, often referred to as a Stage-gate design process.
The project proceeds systematically as described in the sections below. At the end of each stage both parties (HTG and client) are required to review the current stage, make amendments if necessary, and review the future stages in the process. Each stage has specific deliverables, which usually take the form of documents, drawings, or test data.
Every product has it's own particular requirements and characteristics. Additionally, our clients each have unique needs and business conditions. Therefore, before beginning a stage, the client together with HTG will discuss and determine the number and types of deliverables required to complete that stage.
Stage 1: Project Initiation/Feasibility
Based on a client's concepts and expressed requirements, HTG formulates a Product Requirements Specification. This document along with a formal project proposal is submitted to the client. At this point, HTG encourages its clients to develop their own business case and financial assessment, if they have not already done so.
Typical deliverables include:
- Product Requirements Specification.
- Approved Project Proposal.
- Stage 1 Review form.
Stage 2: Preliminary Design
HTG begins design of the product, locates possible suppliers, contacts interested manufacturers, develops a preliminary BOM and cost-up, and generally speaking provides a functional prototype. In this stage HTG will have solved all major technical issues and developed a plan for verification testing.
Typical deliverables include:
- Preliminary Product Specification- including schematics, block diagrams, BOM, drawings, etc.
- Cost analysis.
- Product Test Verification Plan.
- Functional prototype demonstration.
- Manufacturing Feasibility Report.
- Manufacturing Process Analysis and Report.
- Regulatory Requirements Analysis and Report.
- Stage 2 Review form.
Stage 3: Formal Design
A detailed product design specification will be created, describing the product's performance and characteristics in quantifiable ways. The outcome of this stage is technical files that can be used to manufacture the product. During this phase the various components will be selected so that an optimum supply chain solution can be achieved. The complete system will be tested.
Typical deliverables include:
- Hardware - Schematic drawings. PCB Gerbers
- Mechanical - 3D STP files
- Embedded Software - Device Driver source code, Setup and usage documentation
- Server Software - Source code, Setup and usage documentation
- Accurate BOM with cost analysis.
- Several working prototypes
- Product Test Verification Reports.
- Intellectual Property Rights Review.
- Data pack that can be used in future production phases.
- Stage 3 Review Form.
Stage 4: Manufacturing Implementation
Typical deliverables include:
- Purchase Orders for tooling and production test equipment.
- Implementation of procurement plan.
- Finalize verification testing.
- Conduct regulatory approvals and/or testing such as U/L, CE, etc.
- Production machinery installed.
- Initial production run and manufacturing validation.
- Stage 4 Review Form.
Stage 5: Mass production
The product is now ready for deployment through sales channels. Products will be produced according to the released purchase orders. Regulatory Agencies conduct regular follow-up visits.
