Importance of Quality in Business Development

Quality:

Quality the term itself defines the development of the project in best manner which satisfies the users.

In other words the goal of quality management is to meet the standards and regulations the customer needs from the software.

Importance of team for attaining quality:

“Perfection is attainable, but if we chase perfection we can catch excellence” - Vince Lombardi.

Harptec offers a team which always believes that moving quickly is always an advantage but we are not going to sacrifice quality for speed.

"Coming together is a beginning. Keeping together is progress. Working together is success." - Henry Ford.

Quality can be defined in two ways:

External Quality: External Quality refers the quality the user experiences while using the software.

Characteristics of External Quality are: Genuinely Useful, Easy to use, Correct, Robust, Fast, Efficient, Compatible, Adaptable, Secure and Consistent.

Internal Quality: Internal Quality refers to the code-dependent aspects that are not visible to the users and are meaningful to the developers only.

Characteristics of Internal Quality are:Code should be easy to understand, Extensible, Modular, Loosely Coupled, Highly Cohesive, Complaint, Consistent, Reusable, Portable and Documented.

There are three aspects of software quality:

Functional Quality: Means the software correctly performs the tasks according to the requirement of the users.

Structural Quality: Means the code should be well structured.

Process Quality: Means being consistent from one project to another i.e. meeting delivery dates, meeting budget, etc.

For any software company to be successful, the main goal is to understand the needs of the clients and get their feedback. Through this we can get innovative ideas for developing the software.

In short, software developing is the process of implementing the ideas of the customers.

Harptec team believes that quality is a tool and not a goal or a way to describe things. There are no limits in achieving quality or making our work better.

The important aspect in achieving quality work in any field is planning. Every organization should adopt a working methodology so that the team members get clear idea on how they should work to get best results.

For every organization quality of the software should be the main priority as “Good Software leads to Good Business”.

Software does not meet quality aspects on its own, it’s the mixture of developer’s sincere effort, skillful execution, perfect direction and high level of intentions.

“Harptec has no limit to success”.

Testing in coding phase

Testing is very necessary in any field because even a small error can cause havocs! Be it software or any other field, testing is essential before delivering the product to the client.

Here are some tips that will help you in testing a system.

  1. Check if the code is consistent with design:
    Check if the code is written as per the coding standards, and that it follows all algorithms properly. Check if the modular structure of the program is maintained and I/O handling is done.
  2. Testing should be done systematically:
    A plan should be made as to how testing has to be carried out and it should be done as per that. It makes tasks easy and helps organize testing efforts. If errors are found in some part of the code and if changes are made, the modified code should be rerun and checked for errors if any.
  3. Test tools should be used wherever necessary:
    A tester should be familiar with various test tools and compilers available on the system. The choice of test tool depends on what language is used from making the system.
  4. Stress testing should be done:
    The system should be exposed to conditions in which the resources are either overwhelmed or taken away from the system. Both positive and negative results should be noted.
  5. Test one unit at a time:
    Do not rush into testing the entire system at a time. Divide it into logical units and check each individual unit for errors.
  6. Determine when to stop:
    If the errors are still found every time the code is run, the testers should continue with the testing process.

Software testing depends on the cost of an error. Some difficult and significant functions require more testing.

What's the difference between "top-down" and "bottom-up" approach?

Integration testing has 2 approaches:

  1. Big bang approach – In this approach all modules are integrated all at once and then testing is done.
  2. Incremental approach – In this approach, logically related modules are joined. As the process of testing continues more such related modules are added and testing is continued till all modules are tested. Stubs and drivers are used in this process.

Incremental approach is divided into 2 categories:

  1. Top down Approach: In this approach testing process is carried out from top to bottom following the control flow of the system. Main module is divided into sub modules. Stubs are used in this approach. The module which is tested will call the stub. Stub is a dummy module which is created if the sub module is not created and it is used to simulate communication with the calling module.

Advantages

Disadvantages

  1. Fault localization is easy.
  2. High priority modules are tested first.
  3. Major design faults can be detected and fixed.
  1. Lots of stubs have to be created.
  1. Bottom Up Approach: In this approach the testing process is carried out from bottom to up, i.e., the lower level functionalities or modules will be tested first working its way up to the higher level functionalities.

Advantages

Disadvantages

  1. Fault localization is easier.
  2. In this approach no time is wasted in waiting for all modules to build like big bang approach.
  1. Critical modules are tested in the end so they may contain errors.

The winner! Well, there is a tie in this case because both have their own shares of pros and cons. So it is you who should decide which approach you wish to follow depending on your convenience and requirement.
