Software development standards bodies

Many standards are presented in the SQA course. The quality requirements topic of the SQA courses is composed of 3 subjects: models of software quality, definition of software quality requirements and traceability of requirements in the software life cycle. As defined in ISO , quality in use is the degree to which a product or system can be used by specific users to meet their needs to achieve specific goals with effectiveness, efficiency, freedom from risk and satisfaction in specific contexts of use.

In ISO , the product quality model categorizes product quality properties into eight characteristics functional suitability, reliability, performance efficiency, usability, security, compatibility, maintainability, portability. Each characteristic is composed of a set of related subcharacteristics.

As an example, the reliability characteristic, which is defined as the degree to which a system, product or component performs specified functions under specified conditions for a specified period of time, is composed of the following four subcharacteristics: maturity, availability, fault tolerance and recoverability.

Students of the SQA courses are required to continuously measure the cost of rework in their team projects. The Basic profile describes development practices of a single application by a single project team of a VSE. The Intermediate profile is targeted at VSEs developing more than one project with more than one team. The Advanced profile is target to VSEs that want to sustain and grow as an independent competitive business.

Each process is composed of a set of activities and each activity is composed of a set of tasks. Figure 1. On the left side of the table are listed the roles involved in a task.

On the right side on the table, we listed the product required as an input to perform a task as well as the products produced by a task. All tasks are described using this format in the management and engineering guides.

CUS PM. Statement of Work [reviewed] Project Plan. The elements of a typical DP are: description of processes, activities, tasks, steps, roles, products, templates, checklists, examples, references and mapping to standards and models, and a list of tools.

DPs were designed such that a VSE can implement its content, without having to implement the complete framework, i. For the Basic profile, as illustrated in figure 2, a set of nine DPs has been developed and are freely available [1]. Figure 2. At the start of the project, the teams receive a copy of the Statement of Work SOW , which they use to develop the project plan. The professor plays the role of the president of the Acme manufacturing company and the student teams play the role of the software developers of Acme.

At the beginning of the project, the president gives to the teams a SOW describing the functionalities to be developed. As an example, a SOW listed the functionalities of a new model of a washing machine that the president of Acme wants to produce. As an example, four washing cycles were described e. In the description of one washing cycle, the water temperature was given in Fahrenheit F instead of Celsius C.

During that project, once the architecture was finalized, the president came to the developers with a change request impacting a few documents of the project already delivered by the teams e. At another stage of the project, teams were given the high-level schematic black-box of the hardware of the new washing machine e.

From one semester to another, only the SOW has to be changed. As an example, a SOW for the development of software for a rice cooker and a crockpot i. The course website lists the objectives and deliverables for each of the ten-week project. The site also contains all the templates required to produce the deliverables.

The site also includes descriptions of the various types of reviews they have to perform e. These estimates are recorded on a spreadsheet, and every week members of the team must record the hours they have worked on defined project activities.

Also, students must record their rework effort. During the first week of the project, students are also required to select and install the tools they will use during the project.

For example, they must choose and install a document repository tool, a version control tool, and an issue tracking tool. The 6 parts of the project are synchronized with the weekly lectures and reading assignments. One advantage of a traceability matrix is the rapid identification of the software components impacted when requirements are modified, added, or deleted during a project.

A fragment of a traceability matrix is presented in Table 5. This report captures, from their point of view, what went well, what could have been done better and what surprised them during the week project. Many changes have been made to the SQA courses since they were initially set up over 10 years ago. The SQA lectures and laboratory sessions provide a solid foundation for software engineers and software developers, even though SQA is still perceived as a low priority by many software development organizations.

April Alain April and Claude Y. Hermes Publishing, , in French , pp. Charette Robert Charette, Why software fails. They assure the organization that their software products are under the best quality and they are acceptable. They concentrate on certain areas like implementing software development and maintaining the projects by including certain measures:. It is the worldwide federation of national standards bodies, there is a technical committee that prepares the International Standards.

When they collaborate with the electro-technical Commission, they will be able to work with all the electro-technical standardization. There are a number of companies that provides custom software as a service by which you can have the software that matches to all your requirements, when you choose the company based on various relevant factors and also look at the appropriate measures that are required to have the software that is certified to be legal and are approved to have the optimum and authorized use out of them.
