DDI uses an established work process that is precise and logical in order to obtain a foreseeable result, that is to say the commercial success of your products. DDI favors a flexible approach to this process that enables to identify, after discussion with the client, the work steps to be included in the project. Here are the work phases ;

1) PRELIMINARY DESIGN (including):

1.1) Briefing:
This step's purpose is to identify and discuss the goals of the project, it also serves as reference in the evaluation of solutions. The project's essential constraints are also established through briefing.

1.2) Research and documentation:
This step aims at selecting competitive products and at gathering information on their characteristics in order to conduct a detailed analysis.
.
1.3) Competitive analysis:
The objective of this step is to analyze selected competitive products in order to draw conclusions on all the studied aspects (functional, aesthetic, mechanical, ergonomical, economic etc.). These conclusions allow us to determine the design possibilities for a new product.

1.4) Market analysis:
The goal of this step is to define and better understand the target market of the product in question. An analysis of the characteristics of a market and of its consumers will all the more point out the factors to be considered when designing the new product(s).

1.5) Product design:
Through product design, all the knowledge and parameters ensuing from the previous study are put into practice. At this step, the assimilation of the basic information serves as a scale to create optimal and distinctive solutions.

1.6) Visual presentation:
The design propositions are illustrated and presented to the client so as to explain the chosen concept(s).

1.7) Prototype or model:
At this stage, a three (3) dimensional model is developed to visualize the product and to run ergonomical tests on the product.

PHASE 2) FINAL DESIGN (including):

2.1) Technical drawings:
A plan and estimate are elaborated to provide a technical definition of the product (preliminary or production technical drawings).

2.2) Final model or prototype:
Realization of a three (3) dimensional model of the final product design.

2.3) Research of parts manufacturer or supplier:
Selection of potential manufacturers or suppliers for a production cost evaluation of parts or components.

2.4) Pre-production supervision:
Follow up of the production process in collaboration with the manufacturers
