Custom software development

Preliminary investigation of the application context in which the software will have to fit, the characteristics it will have to have and the costs necessary to realise it, the logistical aspects (in the cloud or at the customer's premises) and the development times.
It is necessary to plan feasibility and requirements analysis activities in order to anticipate as precisely as possible any problems to be solved.
Several meetings with the customer are essential to identify the requirements in detail.

Design combines those activities that make it possible to move from the collection and processing of the requirements of a software system to its actual realisation, i.e. from 'what' is to be realised to 'how' the realisation is to take place.

The purpose of design is to define the solution to the problem, through the creation of an outline structure, and to define the characteristics of the individual modules.

Implementation, also known as software product development or coding, consists of the realisation of one or more programmes in the chosen programming language, involving the necessary accessory technologies (databases, scripting languages, etc.). This phase is normally preceded by a prototyping phase, which defines the perimeters, to ensure the realisation of the desired solution.

The testing phase is used to validate the customised software developed, verifying that it meets the requirements identified in the analysis. In this phase, both the individual modules and the entire integrated system are tested. In a customised software development project, testing is not only functional, but also includes strict tests for performance, security, accessibility, etc.

Release is the phase in which the software product is installed in the execution infrastructure used by the customer.

Maintenance includes those sub-activities necessary to modify the software product after release, in order to correct errors, adapt it to new operating environments or extend its functionality.
