Detailed design process

Detailed design drawings

Architectural Design: Architectural design is the specification of the major components of a system, their responsibilities, properties, interfaces, and the relationships and interactions between them. Often a project manager will be appointed to bring all the interested parties together and work towards a common goal which will result in a full detailed design and engineering solution. The goal is to review and track the number of requirements that have been completely designed On the project management side: Number of completed designed components per schedule and development plan. The systems engineer needs to be able to translate user requirements in the language of these disciplines. Where does the Component Level Detailed Design take place in the project timeline? Did each component have a technical review? The detailed design may include: Decomposition of major system components into program units. Was each component design checked for performance? For hardware, this step will describe the hardware elements in enough detail to be fabricated or purchased.

The Embodiment phase of the detailed design and engineering process starts with the concept and develops it into a workable system that can be further developed. It serves to provide a description of the proposed productin terms of a set of integrated ideas and concepts about what it should do, behave and look like in a way that is understandable for users.

This notably varies a lot by field, industry, and product. The engineering design process is a series of steps that engineers follow to come up with a solution to a problem. Design of the internals of the major components is ignored until the last phase of the design.

types of engineering design

Participate in the technical reviews Participate in the evaluation of COTS products Participate in the critical design review Approve the detailed design when completed Gain stakeholder support for the design How do I fit these activities to my project?

Component design tools are essential for component level detailed design and there are many on the market. For small systems that contain nearly all COTS products, the primary activity is the evaluation of these products.

Detail design phase

Basically, conceptual design is the very first stage of the product design process, where drawings and other illustrations or models are used. This is especially true for software development. The drawings produced are often quite simple ideas with little detail, but the aim of the conceptual phase is to commit ideas to paper. Each of the system requirements should be traceable to a sub-system element. Was a critical design review conducted? Ideally this is done as late as possible in the timeline to provide the latest technologies at the best price. Equally if the phased process described above is done poorly it can have a major negative impact on the overall project success. For example, prototyping graphical user interfaces for workstation will allow the stakeholder to discover features and functions that they will like or dislike before software coding. The design requirements control the design of the product or process being developed, throughout the engineering design process. If your project involves making observations and doing experiments, you should probably follow the Scientific Method. At this step Developmental Configuration Management is used. Issues in architectural design includes: Gross decomposition of the systems into major components. Often a project manager will be appointed to bring all the interested parties together and work towards a common goal which will result in a full detailed design and engineering solution. The goal is to minimize changes to requirements Incomplete design leads to increased technical risk and increased cost. This process is different from the Steps of the Scientific Method , which you may be more familiar with.

The software design process can be divided into the following three levels of phases of design: Interface Design Detailed Design Interface Design: Interface design is the specification of the interaction between a system and its environment.

The goal is to minimize changes to requirements Incomplete design leads to increased technical risk and increased cost.

Preliminary design

Unit Verification Plan is used to verify that the components work as designed. Detailed design is such a fundamental necessity to manufacturers that it exists at the intersection of many product development processes. Was a verification plan for each component defined? This continuity between the component design and development is critical. For hardware, it is the step where logic schematics, chip layout, and artwork are being prepared for fabrication. Each of the system requirements should be traceable to a sub-system element. In this example, as in many other instances, it is therefore necessary for all elements of the problem to be considered and the most suitable decided upon during the build up of the detailed design and engineering solution.

If COTS equipment is being used, this step is where alternative candidate products are evaluated and a selection is made.
