The Validation and Verification Model – The V-Model

What is V-Model?

V-Model is mostly known as the validation and verification software development process model (The Vee Model), and It is one of the most know software development methodology. Although it is considered as an improvement to the waterfall model and it has some similarities as the process also based on sequential steps moving down in a linear way, it differs from the waterfall model as the steps move upwards after the coding phase to form the typical V shape. This V shape demonstrates the relationships between each phase of the development life cycle and its associated phase of testing.

The Software Process Improvement (SPI) – Reward or Risk

Most of the Software companies large, medium, small, or startup usually face issues in their software development projects and its delivery. The issues can vary from lack of documentation, lack of following the process, lack of process governance, lack of the integration and collaboration between the teams, lack of requirements traceability, lack of technology management, …etc.

We have discussed in a previous post the trends of software projects and that large software projects on the average run 66% over budget and 33% over schedule; as many as 17% of projects go so badly that they can threaten the existence of the company.

Therefore, some methods and techniques started to exist to tackle the software process issues to suggest different improvements and identify issues and inefficiencies in the process. These methods became a standard which the companies can follow to improve their software process. Moreover, each method established its ecosystem, from providing the training and certificates for the method to provide consultancy to help companies to improve based on actual practices.

In this article, It will be good to ask yourself if the software process improvement is a peril to have or a promise for a better change for the organization and to have a superior advantage in the market. For answering this, we will discuss in this article what is SPI?, what is the SPI process steps? what are the different methods?, the motivators and demotivators of SPI projects, what are the common success factors for SPI project implementation?

Quality Attributes, measurements, and implementation strategies

The system should be easy to use.
The system should be flexible and scalable.
The system should be secured.
….
….
The system should be portable.

Did you read any requirements document and found one of the requirements statement mentioned above? Then, you started to think, what does it mean to make the software ease of use, how can I make that feasible, if I implemented that feature would the software became more usable? would it be acceptable to the customer? What are the metrics and acceptance criteria for that? How to transform these intangible requirements into something tangible can be implemented and measured.
