How to write a specification document architecture

This use case allows a student to register for courses in the current semester. Specification writers frequently meet with manufacturers of building materials who seek to have their products specified on upcoming construction projects so that contractors can include their products in the estimates leading to their proposals.

Specifications are an integral part of Building Information Modeling and cover the non-geometric requirements.

Functional specification

This approach is unusual in North America, where each bidder performs a quantity survey on the basis of both drawings and specifications. Such a requirement describes an interaction between an external agent the user and the software system. Many owners welcome substitutions.

Process[ edit ] In the ordered industrial software engineering life-cycle waterfall modelfunctional specification describes what has to be implemented. Food and drug specifications[ edit ] Pharmaceutical products can usually be tested and qualified by various Pharmacopoeia. The next, Systems architecture document describes how the functions will be realized using a chosen software environment.

In addition, specifications can be "closed" with a specific list of products, or "open" allowing for substitutions made by the Contractor. He described it as two words in a specification that make subcontractors want to turn away and run as fast as they can in another direction.

We agree that a substitution is a change, but what kind of a change, and how a substitution is supposed to be evaluated, are where the differences of opinion and misunderstandings occur. The general contractor pointed out that team members treat substitutions differently depending on the project delivery method.

This is a consensus document that is jointly sponsored by two professional organizations: And when design changes have to be made due to a substitution, it is hard to be sure one has gone back and checked every possible thing that could be affected, as was done when the design was first developed.

Specification (technical standard)

The benefit of this method is that countless additional details can be attached to the screen examples. Such a requirement describes an interaction between an external agent the user and the software system. Logical View A description of the logical view of the architecture.

Examples of functional specifications[ edit ]. This section will explain how to prepare the materials and conduct the installation, including the testing requirements to be followed.

They are prepared by construction professionals such as architectsarchitectural technologistsstructural engineerslandscape architects and building services engineers. The billing system is notified for each student in each course offering that is not cancelled, so the student can be billed for the course offering.

Architecturally Significant Use-Cases 4. Performance specifying transfers some design duties and control from the design team to the contractor team. Specification writers are either employees of or sub-contractors to architects, engineers, or construction management companies.

The actor in this use case is the Professor. This use case allows a Registrar to close the registration process.

Functional specification

Boundary classes exist to support login, maintaining of schedules, maintaining of professor info, selecting courses, submitting grades, maintaining student info, closing registration, and viewing report cards. The actor in this use case is the Professor. This use case allows a professor to submit student grades for one or more classes completed in the previous semester.

In many countries on the European continent, content that might be described as "specifications" in the United States are covered under the building code or municipal code.

The owner and design team need to define how casual or formal the process for evaluating substitution requests is. Substitutions scare architects, and for good reason. This use case allows a professor to submit student grades for one or more classes completed in the previous semester.

Quality control requirements, acceptance samplinginspections, acceptance criteria Person, office, or agency responsible for enforcement of the specification. In fact, in most cases, the construction specifications override the project drawings in the event of conflicting information.

These use cases are initiated by the student, professor, or the registrar actors. The Course Catalog System is an actor within the use case. Provisions for rejection, reinspection, rehearing, corrective measures References and citations for which any instructions in the content maybe required to fulfill the traceability and clarity of the document [12] [13] [14] Signatures of approval, if necessary [15] Change record to summarize the chronological development, revision and completion if the document is to be circulated internally [16] Annexes and Appendices that are expand details, add clarification, or offer options.

Usually, the second version of the specification is good enough to start the project, though you might want to go into more detail and iterate more.

Owners such as municipalities, public school districts, and universities may own and maintain many buildings, and need maintenance procedures to be the same from building to building.

Subcontractors, who are specialists in their areas, can keep up, and may be able to offer better solutions. Specifications are an integral part of Building Information Modeling and cover the non-geometric requirements.In (hardware, software, or enterprise) systems development, an architectural specification is the set of documentation that describes the structure, behavior, and more views of that system.

Program specification. A program specification is the definition of what a computer program is expected to do. Basically they all refer to a “specification document” like A&E. A&E is an interesting document, closer to a “design spec sheet.” It includes detailed technical/engineering characteristics of.

Construction Specifications. According to the American Institute of Architects (AIA) Document A, the Contract Documents for a construction project consist of “the Agreement, Conditions of the Contract, Drawing, Specifications, Addenda ”, as well as other miscellaneous documents associated with the contract between the project Owner and the Contractor hired to complete the work.

Technical specifications, at least in the form of a technical design, are part of the design documents, along with, for example, requirements lists, functional designs, user stories, graphics design mockups, usability studies, UML diagrams, business process diagrams, data model specifications, etc.

This document describes the Technical Architecture of the System that satisfies business requirements as documented in the Business Requirements Document, and implements the functionality and satisfies technical, operational and transitional requirements described in the Functional Specification.
