What is a specification?
A specificationis a document that specifies a system or product, e.g. a prime-item development specification for an F-14. There are lots of sections/content in a spec: requirements, definitions, reference documents, glossary, verification information, etc. .
What is a requirement statement?
A requirementis a single statement of something the product or system must do. A spec may have hundreds of requirements in it. Old school methodology says the requirement statement must use the word "shall", to separate requirements from statements of facts, or definitions.
What is specification in engineering?
A specification is a requirements document — end of story. It’s a widely accepted term of art across more fields that aerospace and defense and is unassailable within systems engineering, which is the discipline responsible for requirements and verification.

It can feel productive to start specifying how a project will work from the very start, from workflows to designs. This is almost always a dangerous illusion and a reliable way of making an exact and flawed product.
What is specification in engineering?
A specification is a specific record. In the two most common engineering contexts, we have requirements specifications and design specifications. The first is a specific record of a set of requirements; the second is a specific record of a design.
Is a specification a specific record?

What is program specification?
Program specifications are mostly similar to functional specifications. Both of them aim to illustrate the functions of a given software. Some organizations don’t even distinguish between the two. When the two are differentiated, however, it’s typically to distinguish formality levels.
Is functional specification formal or informal?
Whereas functional specifications are more formal, program specifications are informal. Unlike formal specifications, program specifications don’t require a ton of math expertise. Software developers might look at them as a type of proto-user guide for that reason.
What are architecturally significant requirements?

What are the two subcategories of system requirements?

The difference between requirement and specification in Software Engineering is that a requirement is a need of a stakeholder that should be solved by the software while a specification is a technical document with the analysed requirements.
What is software specification?

Specifications: No Substitute For Requirements
The Destination Is Not The Route
- Consider this scenario. You’re out on the street in Istanbul preparingto head to the Istanbul Modern to take in some Turkish art prior toleaving the next day. It seems fairly far away and you don’t have yourown car, so you find a taxi to get there. The first thing you do after getting in the taxi is to tell the driverwhere you want to go. You’ve seen the map and which streets offer themo…
Requirements and Goals
- It’s possible, too, that our driver might have told us that given thetraffic congestion, our limited time, and short distance, that it wouldbe in our best interest to walk or perhaps to take a different mode oftransport. On the street in Istanbul, we stopped short in talking only aboutrequirements. Here we’re still relying on the driver as only a technicalexpert to decide on and navigate a route t…
Making This Possible
- This kind of discovery is only possible with expertise and trust. To aconsultant it means making sure your clients understand and trust your expertise,and asking them questions when they specify routes. To a client it meansgoing beyond specifying a route and explaining where you’re trying to goand also why you’re trying to get there.
