Fundamentals of work of construction software developers include:

  • Minimization of complexity
  • Waiting for changes
  • Verifiable design
  • Design standards

The first three concepts apply not only to design. But also it’s applied to design. And it forms the basis of modern methodologies for managing the life cycle of software systems.

Minimizing Complexity

The main reason why people use computers for business purposes is the limited ability of people to process and store complex structures. Also it’s applied to the large amounts of information. In particular, it’s over a long period of time. This consideration is one of the main driving forces in software design: minimizing complexity. The need for complexity reduction affects all aspects of design. And it is especially critical for verification. And it’s testing of design results, i.e. the software systems themselves.

Reducing complexity in software design is achieved with a focus on creating simple and easy-to-read code. Albeit at the expense of making it perfect. For example, from the point of view of flexibility or adherence to certain ideas about the beauty, sophistication of the code, dexterity of certain techniques that allow it to be reduced to the detriment of size, etc. This does not mean that the use of certain developed language capabilities of the programming tools used should be infringed upon. This means “just” giving more value to code readability. It’s ease of testing, acceptable performance levels, and meeting specified criteria, instead of continually improving the code, regardless of timing, functionality. And there are other characteristics and constraints of the project.

Waiting For Changes

Most software systems change over time. There are many reasons for this. Anticipation of change is one of the driving forces behind software engineering. The software is not isolated from the external environment. These are both systemic and from the point of view of the field of activity, for the automation of tasks and problems of which it is used. Moreover, software systems are part of a changing environment and must change with it, and, sometimes, be a source of changes in the environment itself.

Verifiable Design

Designing for verification suggests that the construction of software systems should be carried out in such a way that the software system itself helps to search for the causes of failures. It’s transparent for the use of various verification methods. This is precisely the meaning laid down in the original title of this topic. And, by the way, making the necessary changes. They are both at the stage of independent testing (for example, by test engineers). And in the process of operational activities – operation, when the ability to quickly detect and correct errors that arise is especially important.

Among the techniques aimed at achieving this design result by enterprise web development company Fireart are:

  • Review, code evaluation.
  • Unit testing.
  • Structuring code for and in conjunction with the use of automated testing tools.
  • Limited use of complex or difficult to understand language structures.

Design Standards

Standards that are directly applicable in design include:

  1. Communication methods (for example, standards for document formats and content design).
  2. Programming languages ​​and associated coding styles.
  3. Platforms.
  4. Tools.
  5. Use of external standards. Design depends on external standards related to programming languages, tooling used, technical interfaces, and the mutual influence of Software Design and other areas of software engineering knowledge (including related disciplines such as project management).
  6. Use of internal standards. Certain standards, conventions and procedures can also be created within the organization or even the project team.

When combined with external standards, internal standards are intended to define the general rules of the game. They are applied for all members of the project team. It’s done by agreeing on terms, procedures and other significant agreements.
