It is an iterative document that reflects the plans and intentions of the development team. As those change, so must the specification change.
But where the other transitions were linear, this last one was exponential. While in the past you got your marching orders from an employer that worked with clients or was itself in the software business, now all those responsibilities that were once distributed between expert-testing, program management, etc.
This is a far greater challenge than it appears. You will get a very general idea of what the software is supposed to do, look like, and flow. At each stage, you must iterate your way closer to agreement.
Why Software Design Documents Matter So, when you take on a new project, before you even open Xcode or Visual Studio, you need to have clear and agreed-upon design goals. And these goals should be established in a specification document.
If anything, the client will apologize for letting the imprecision slip through in the first place. We all want satisfied clients.
We all want a friendly working relationship. And we all want the pride of a job well-done. If the client still insists that you advance without such a document, you should accept the fact that you have an unworkable relationship and walk away. At the very least, it should be a description of the desired application, criteria for completion, and milestones.
Remember, you are sharing what is best described as a requirements and function document, not an implementation specification.
And unless a specific implementation is a stated client objective, how you make it work is up to you. User Interface Most projects are applications, not libraries or frameworks.
But if you happen to have one of these as a deliverable, count yourself lucky because the user interface is far and away the most problematic component of your design document template, and almost always leads to misunderstandings.
Many clients will send you perfect illustrations created in a graphic editor by a graphic designer who is not a programmer. But the problem is: Does it disappear when unusable?
But these illustrations say nothing about animations, control states, or even what actions to perform when a button is pressed. Before you start writing the code behind these illustrations, you should be able to answer all of those questions.
Specifically, you should know: Under what conditions do their states change?Specifications vary considerably depending on the stage to which the design has been developed, ranging from performance specifications (open specifications) that require further design work to be carried out, to prescriptive specifications (closed specifications) where the design is already complete.
Design documents are also referred to as functional specifications or functional specifications documents (FSDs), or functional requirements specifications. What is a high-level design document?
A high-level design document (HLDD) describes the architecture used in the development of a particular software product. The process of specification writing, conducted in parallel with design and drawing work, helps create the proper balance between client, statutory, technical and aesthetic requirements.
