Why the Application Design is Needed
While the application specification tells us what the application should do, the application design tells developers how they should technically implement its functionality. The design is prepared by the software architect, the most experienced person in the team. It specifies in the smallest details how the application code should be organized, leaving no room for potential misunderstandings. The design also allows for more accurate estimation of the time and costs required to build the application.

What the Application Design Includes
Conceptual Design of the Application Interface
This should not be confused with the graphic design. It is a set of conceptual drawings that depict the contents of individual screens of the application, along with descriptions of their behavior. Contrary to appearances, this is a very important element of the design because the thoughtfulness of the interface design determines the intuitiveness and ease of use of the application. As a result, it significantly contributes to its success.

Database Design
An ERD defining the structure and relationships of the individual tables in the database. A properly designed database translates into the application's performance and the ease of maintaining the code.

API Specification
Prepared according to the Open API 3 standard, a YAML document defining all the functions of the application. It describes the back-end / front-end interface of the application.

The Design Allows for Estimating Further Work
With the completed design, we can finally move on to accurate time and cost estimates for creating the application. After the project is finished, you'll know what to expect and can make decisions regarding the next steps. Regardless of your decision, the design becomes your property. You can choose to proceed with us or with another team.
How Much Does the Design Cost
The process of creating an application design consists of three phases.
The first phase is preparing the interface concept. This is the stage where we invite the client to review and ensure that the proposed application screens meet their requirements. This phase typically takes about one business week.
The next two phases, which are the database design and the API specification, begin immediately after the client approves the interface concept. These phases also usually take about one business week. The exact time and cost of the application design depend, of course, on its level of complexity. It is safe to assume a cost range of 10,000 to 20,000 PLN (net).
We invite you to a no-obligation call, lasting about 45 minutes, where we will analyze your case, determine if it falls within our area of expertise, and help you take the next steps.
