The 8D Process of Creating a Custom Web Application

When you sign on with Ontrix’s custom web application development services, you’re signing on with professionals who know how to deliver what you need.

In the Discover stage of the project, the team (artists, engineers, content experts, producers … everyone!) works to plan a shared vision of the product. What are the specific product needs? What is the message? What are the learning goals? What are the business goals? Who is the primary audience? Is there a secondary audience? How will that experience differ? What type of experience do we want the user(s) to have? How will we define success for the project? What are the product expectations in the market currently? This is the time to combine creative brainstorming, child development theory, and business savvy, keeping in mind the realities of a project’s budget, timeline, and technical parameters.

Once the team identifies the project’s overarching goals, it’s time to define on paper what that final product will be cleared. At this stage, it’s essential to have a “user-centered” design approach, ensuring the needs of the end-user are met during every step of the interactive experience to be defined. With that in mind, determine individual user’s navigational flow through the product—Spec out the interactions of each screen. Create the functional, design, and technical documentation to define not only what the product will do but how (technologically) it will be achieved. Documentation essentially places a “soft freeze” on the definition of the product and allows a team to move forward with its development.

Throughout the definition phase, many challenges of design are considered. How will the screens look ? How is this product going to be branded? Are there characters? If so, who or what are they? How will they look? How will they interact with the end-user? Is the look of the project to be edgy? Cuddly? Businessy? How will the user navigate through the experience? All questions will be answered during the design stage of the project. This is also where the design team will determine the final look/feel of the project … the project’s style. Through the process of sketches, storyboards and interactive examples, the design team will develop the graphical user interface (or GUI) for the project as well as pull together all needed assets for the final product, including illustrations, animations, photos, videos, and audio.

In this stage, all of the vision, definition, design, and understanding of the project come together. In this stage, the artists, programmers, and content experts work feverishly to create workable, interactive prototypes of the final product. This stage is filled with “alpha” deliverables, small snippets of working prototypes that allow the team to see the project in action. The goal is to build alphas as “solidly flexible” as possible. That is, while you will want the alphas to be solid building blocks for the final product, they also need to be created in such a way that it allows for minor tweaks and adjustments that the development team feels will improve the overall user experience.

The Debug stage is critical in the process of completing a project. As the Debug stage starts, the development team will lock down the functionality for this release of the project and focus on technical issues standing in the way of a successful launch. This version of the project is its “beta” and is functionally complete (everything works!) and content complete (no placeholder art or content). The beta will be tested on various platforms, and any issues (“bugs”) will be identified, cataloged, prioritized, and solved.

The goal of this stage of the project is to take a final look at the product to ensure that all of the bugs previously identified have been addressed to everyone’s satisfaction. Once everyone is in agreement that the product is complete and in good condition, it will be considered “gold.”

You’re done! The final product is released to the target audience and the team begins work on the debrief process (How did development go? What can be done to make the next project work even better? What was the greatest success during the project? What should be done differently?) Capturing this information after a product is deployed can be of great value when you begin to develop your next product.

We provide debugging service and create additional features on an as-needed basis. You receive full help desk support services.
