    conception Functional identification following a need emerging from the case studies the method to be implemented is identified Complete mathematical description of the method for this part the references are found Among all the sources the most obvious are scientific articles and books The references should cover the whole algorithms and concepts involved in the development of the function Structured mathematical description this document describes the mathematical process followed by the method This description is self sufficient homogeneous in terms of notations and as structured as possible to make the emergence of concepts as easy as possible The software conception is based on this document Software conception from the structured mathematical description it is then easier to choose the objects that are implemented It highlights the services attached to the objects the dependencies with other objects and or the possibility to use existing objects Development when the conception is done the development starts It consists in the implementation of the objects and algorithms Opus has a set of development rules that should be followed in all cases but must be followed if the contribution is to be integrated at the Opus Lib level See the Programming Rules guide and following articles for more detail Test cases and unitary validation this step is required in order to demonstrate that the development is correct Each object and methods should be tested and validated with comparisons with analytical methods or reference methods Documentation of the development a documentation of the development is required in order to secure the development and its maintainability There are several types of documentation Reference documentation it contains the mathematical basis of the method developed It is based on the structured mathematical description Architecture documentation it describes the architecture of the different objects developed and their link with the
