The solution design is a key step in the execution phase of a project. This process provides a complete and detailed design of the project solution.

1. The first step is to build on the functional and technical analyses conducted earlier in the project execution phase to identify possible solutions. These can be proposed on the basis of questions such as:

• What are the desired objectives?
• How can the objectives be achieved?
• What is the scope and timeframe of the project?

2. The second step consists of evaluating each proposed solution on the basis of the collected needs and defined objectives:

• Does the solution respect the timeframe for the project?
• Is the solution within the project budget?
• Does the solution meet the customer's needs?
• Is the solution aligned with the expected quality?
• What are the risks associated with this solution?

3. The third and final step consists of selecting the best solution and detailing its functional and technical specifications. These can then be formalized through BPMN schema 👇, Word document and/or Excel file.

BPMN schema

Business Process Model and Notation (BPMN), also known as "business process model and notation", is a modeling method that describes all the steps required to complete a business process.

It allows to graphically represent all activities, value chains, information flows and stakeholders of the process. Its use facilitates communication through clear and unambiguous modeling, as well as process improvement through the simplified identification of sources of inefficiency.

The basic elements of BPMN diagrams are:

• pools and lanes representing the stakeholders;
• activities representing the decomposition of the process;
• events;
• sequence flows representing the sequence between these elements;
• gateways allowing to split or to converge control flows;
• messages allowing to materialize the exchanges;
• data;
• annotations and associations between linked elements.

 
Tips for creating BPMN diagrams:

1. Clearly define the beginning and end of the process;
2. Diagram the main steps of the current business process;
3. Break down the important steps into sub-steps, indicating their links to the different stakeholders;
4. Place activities, events and control flows horizontally, associations, messages and data flows vertically;
5. Try to fit the entire process on one page;
6. Create several versions of the diagram depending on the level of detail required by the stakeholders.
