design constraints vs requirements
C Performs intended purpose within required tolerance/specification? We use a ‘Design the Box’ exercise to help teams cultivate a shared understanding of a product/project vision. Design Criteria and Requirements (Constraints) These are some general questions that might be asked during brainstorming and design evaluation. Table 5.1 . This post is intended to address the VCAP design objective around determining risks, requirements, constraints and assumptions. Some other types of requirements that in my experience are often overlooked until sometimes at the last minute, if at all, are constraints. Requirements and Constraints A constraint is a statement of restriction that modifies a requirement or set of requirements by limiting the range of acceptable solutions. At the time of writing, the required ‘Skills and Abilities’ listed by VMware for this topic are: Differentiate between the concepts of risks, requirements, constraints … Although obviously requirements and constraints are related, we need quite different types of attributes and metadata for each: for example, at the design/logical-level, requirements should be ‘timeless’ and implementation-agnostic, whereas constraints are context- and implementation-specific. Assumptions¶. Design constraints are conditions that must be met for a project to be successful. Functional or Non-Fuctional requirements. Based on the above, reno makes a couple of assumptions about the release policy used for a given project.reno expects all development, including bug fixes, to take place on a single branch, master.If stable or release branches are used to support an older release then development should not take place on these branches. Function, Constraints… The focus of the question depends on if you are designing a product, system, or process. A straightforward approach to address design constraints is to categorize the type of constraints (e.g., hardware, software, procedure, algorithm), identify the specific constraints for each category, and capture them as system requirements in the Requirements package along with the corresponding rationale. This is a quick blog post detailing the difference between requirements, constraints and assumptions in an IT context but it probably maps to other industries as well. The first step in relating design requirements to material properties is a clear statement of function, constraints, objectives, and free variables.
