Product design specifications (PDS) is the bare bones description of what the product must deliver. A product design specification can be used as the foundation or ‘blueprint’ for any product development project. The basic job of a product designer is to describe and understand the product design specification. A product design spec is used as a guide for both initiation and development of new product designs. The product design spec helps a team to determine the most appropriate and cost effective technical solution to a given problem.
The product design specification (PDS) is often the first document in the product design process. Many projects begin with a series of feasibility documents that outline the product requirements of the project, the constraints and the goals of the project. These documents assume a formal format where each document corresponds to a particular section of the project schedule. However, the PDS provides much more detail than a schedule because it addresses many issues that become issues throughout the project.
The product design specification should include the broad scope of functionality desired by the end users. In addition, the specifications must describe all of the product’s major uses: marketing, functional, ergonomic, aesthetic and structural. It should also describe all of the product’s potential use in unique or specialized ways. The product design specification should also take into account any environmental factors that may affect the product’s operation. The specifications must describe all of the product’s key performance indicators (KPIs), as well as all of the methods and techniques used to measure those KPIs.
Each PDD contains a resource document that defines the technical requirements of the project. Each of the individual technical requirements must be specified, together with their relative weights. A project plan is usually included within the documentation. PDDs also include risk management documents and software testing documents. The product design specification and its supporting documentation can form the foundation for additional, developer-directed requirements.
PDDs describe a product design process from start to finish. Each step in the process must be documented, which helps the developers to understand the critical steps and optimize the design process. In addition, the documentation can help to determine the business case for implementing a specific technology. While each stage of the design process is very important, the product design specification is perhaps the most important document in the entire process.
Each product design specification will have an optional structure, or interface. These interfaces represent “call to action” statements. Each interface has a default behavior, but some designers choose to define custom call to action interfaces. This enables them to control the user experience based on their knowledge of the target audience. Furthermore, they may use this information to control accessibility, to make the process more efficient, and to ensure the compatibility of future software releases.
Often product specifications are referred to as requirements. Requirements often describe the scope of work that must be performed during the development process. While many software packages have formal requirements, often these are only formal to the software package’s point of view. The product design specifications should provide sufficient detail to define the scope of the development process, ensuring that the project meets the organization’s goals and objectives.
Design specifications are designed to give the project team a clear understanding of the product design specification and associated requirements. The specifications describe the expected functionality, quality, and compatibility of a product according to the original design, specification, and planning. The product design specification ensures that the project meets the original goal and deadline, and that it is economically and schedule-efficient.
