Which project approach is best for which type of development project?

What are a project approach and a development track?

A theoretical approach to project management is the project approach. The latter is a collection of methods for successfully planning and executing a project (for example, an ICT project to optimize a particular business process).

A development path is the process that must be gone through to realize a (final) product. This development process starts with defining the desired characteristics of the product and ends with its release for serial production.

Which project approach suits which type of development project?

Within Confed, we use two different ways to execute a project approach: the V-model and Time material methodology. Which approach is chosen for which type of development depends on specific points within the project. We explain for each project approach.

The V-model

The V-model suits projects where the principles can be well defined, and we can give the client a clear understanding of the development costs in advance.

When there are uncertainties about feasibility or technical design choices that may greatly affect the design process, it may be chosen to start first with a Proof of Concept phase. The aim is to identify the uncertainties, and minimize risks.

The V-model methodology consists of 2 branches, on the left are the design steps, on the right are the test steps. Each design step has a corresponding test step. The project starts with a definition defining the requirements and the corresponding acceptance criteria.

Then the system architecture is determined, followed by detailing the design of the product's sub-blocks. Then the implementation is carried out for these sub-blocks. After completion of the implementation, the test steps follow where first the sub-blocks are verified in detail, followed by validation, integration and acceptance testing.

Time material Methodology

The Time Material methodology fits well in projects where the client requires a lot of flexibility. This may be the case in situations where the starting points cannot yet be clearly defined at the outset. For example, the desired properties may still be influenced by the outcome of the first development phase. In these situations it is important to offer a lot of flexibility, while at the same time monitoring the costs of the project.

To provide this flexibility in combination with cost control, the project is divided into a number of work packages.Prior to each work package, the activities that will be performed are determined in consultation with the client. A ceiling is also set on the available budget for hours and materials. At the end of each completed phase (work package) the results are shared. Subsequently, agreements can be made about the next work package with the corresponding budget.

Project approach by development process at Confed

So which project approach is chosen for each development project depends on several factors. We find it important to look at the requirements, resources and expectations for each company and project and, of course, respond to these as best we can. A combination of both methods can also be chosen in advance. It is quite possible to choose a "Time material" approach initially for the first, more uncertain phase. Once the starting points are well defined and a clear understanding of the required development budget can be given, one can then switch to the V-model.

Confed looks with you per company and project, what the best project approach is. Of course we are happy to discuss this with you!
