Project Documentation

When it comes to defining user requirements for software, it is essential to use models to document and analyze the project requirements. We create model roadmap that helps software development teams understand the effective use of requirements models. Our Project Documentation also describes good practices for creating and using these models. Many software developers have a love-hate relationship with requirements. They love having a list of things they need to engineer into the product they are building, but they hate it when the requirements are unclear, inaccurate, self-contradictory, or incomplete.

A Short Review of Project Documentation Requirements

Before we get to the building requirements models, let us look at some basic requirements concepts.

Project requirements

Business requirements

Project Documentation define Business requirements. Statements of the business rationale for the project. These requirements grow out of the vision for the product which, in turn, is driven by mission (or business) goals and objectives.

User requirements

Project Documentation define User requirements. The software requirements from the user’s point of view, describing the tasks users need to accomplish with the product and the quality requirements of the software from the user’s point of view. The product’s vision statement articulates a long-term view of what the product will accomplish for its users. It should include a statement of scope to clarify which capabilities are and are not to be provided by the product. Users can be broadly defined to include not only the people who access the system but also inanimate users such as hardware devices, databases, and other systems. In the systems produced by most government organizations, user requirements are articulated in their concept of operations document.

Software requirements

Project Documentation define Software requirements. Detailed descriptions of all the functional and nonfunctional requirements the software must fulfill to meet business and user needs. Nonfunctional requirements include software design constraints, external interfaces, and quality attributes such as performance, security, installation ability, availability, safety, reusability, and more.

Project Documentation also define Software requirements, which are documented in a software requirements specification, establish an agreement between technical specialists and business managers on what the product must do. The key activities in requirements development are the following: elicitation, analysis, specification, and validation. In elicitation, you identify the sources of requirements and solicit requirements from those sources. Requirements elicitation relies on appropriate stakeholder involvement, one of the most critical elements for project success.

The goal of project requirements analysis

The goal of project requirements analysis is to sufficiently understand and define the requirements so that stakeholders can prioritize and allocate them to software. Project documentation involves differentiating and documenting functional and nonfunctional requirements and checking that the requirements are documented unambiguously and completely.

Validation examines the project requirements to ensure that they satisfy user’s needs.

Elicitation and analysis are crucial early activities that require intense stakeholder involvement. To analyze the requirements you are eliciting, a key good practice is to create requirements models (also referred to as analysis models): user requirements represented by text (such as tables, lists, or matrices), diagrams, or a combination of text and graphical material. These models facilitate communications about requirements with your stakeholders. As you elicit requirements from stakeholders and represent them using requirements models, you should verify your models to ensure they are internally consistent.

The price is high for teams that fail to define project requirements or that do it poorly. The consequences of these defects are ugly:
* Expensive rework and cost overruns.
* A poor quality product.
* Late delivery.
* Dissatisfied customers.
* Exhausted and demoralized team members.

To reduce the risk of software project failure and the costs associated with defective requirements, project teams must address requirements early in software development and they must get professional project documentation.
