Q

Actor

A

Part of a use case diagram. A role, thing, event/timer, or external system that interacts with the proposed system. The actor either stimulates the system (provides input) or receives output. An actor is outside the system documented in the use case diagram.

A

The concept that gathering requirements involves more than just holding out your arms and expecting the stakeholders to throw you the requirements. Gathering the requirements involves really probing the users
and really understanding what they need and why they need it.

Gap analysis

A

The process of identifying the difference (“gap”) between where your client is today, and where the client wants to be in the future, and of then identifying the new functionality to minimize or eliminate the gap.
The “gap” is best described in terms of a measurable quantity with units, such as time, but not as a percentage.

Key process areas (KPAs)

A

The main component of the CMMI. The
processes that an organization needs to focus on. For example, to move to Level 2, an organization focuses on six KPAs, then on seven more KPAs to move to Level 3. The KPAs are split between software engineering (e.g.,
software quality assurance, requirements management) and project
management. Requirements management is a Level 2 KPA.

Q

Product scope

A

Product scope defines the features and functions that
characterize a product or service. The product requirements define the scope of the product, starting with the problem to be solved and the vision to be achieved through the solution of that problem.

Q

Project scope

A

Project scope is defined by the work that must be done to deliver a product with the specified features and functions. Project scope is stated in a set of project requirements that include the product requirements,
the developers, the language used, the deadline imposed on the project, and the testers. Project requirements incorporate the full development life
cycle, of which the requirements development is one phase.

Q

Quality Function Deployment (QFD)

A

A methodology to develop or refine a product, service, or process. Started in Japan in the 1960s, it is
implemented in both manufacturing and service industries. The work is carried out by a cross-functional team within the organization, focusing on what features matter most to the customer or user of the product or service.

Q

Requirement

A

A requirement is a thing that is needed or wanted; a
statement defining a capability, characteristic, or constraint for a product, service, or event. Requirements define capabilities needed by a user to solve a problem to achieve an objective. These capabilities must be met or possessed by a product to satisfy a contract, standard, specification, or other formally imposed documentation.

Role

A

The traits that an actor in a use case undertakes. Roles, not individual people or things, are modeled in use case diagrams. For example, an adult in the role of a parent, puts a child to bed, makes lunches, and drives to sporting events. That same adult in the role of employee goes to work and earns a paycheck.

scenarios in which the documents will be used.

42
Q

Sponsor

A

A type of stakeholder such as the one who oversees and supports the project, often at the executive management level.

43
Q

Stakeholder

A

Anyone with a vested (substantive) interest in the project. Individuals and organizations that are actively involved in the project, or whose interests may be positively or negatively affected as a result of project execution or project completion. They exercise influence over the project and its results and contribute to requirements development activities.

44
Q

45
Q

System requirement

A

The degree to which a relationship can be established between two or more products of the development process.

47
Q

A

A table or mapping between two statements, two requirements, two paragraphs, two “chunks” (sections) of code, etc. If downward traceability is complete through the entire life cycle, no requirements are dropped. If upward traceability is complete, no unneeded capabilities (requirements, design statements, code, test cases, etc.) have been added.

48
Q

Use case

A

A set of capabilities that define the user’s needs. One passes through a system. A transaction, process, or set of steps in a logical order. Each use case, written as a verb phrase (e.g., pay for phone calls, withdraw
money from ATM, process inventory) is a set of functional requirements grouped into logical scenarios from the user’s perspective. Use cases only capture functional user requirements—not system or software requirements, nor non-functional requirements of any type. A set of use cases + actors + associations + system boundary make up a graphical use case diagram of the system.

53
Q

User requirements

A

A generic term encompassing the functional and nonfunctional requirements that come directly from researching the stakeholders (as in Method 503F). “The user shall…”. The user requirements are refined into the system and software requirements during the analysis phase (which follows the user requirements phase of a project).

54
Q

Validation

A

Confirming with the stakeholders and the team that the
documented requirements are consistent, complete, and accurate. Getting formal agreement that the real requirements are present in the requirements specification.
