Not to be confused with visual designs, wireframes are not very visually impressive and only act as a blueprint of our application. Using wireframes we lay out how our application will be structured, what information will be displayed and what kind of controls will be used to implement specific features. They are a lot easier to prepare than visual designs and are a great tool to align the vision of the project with you early on. Once wireframes are prepared and confirmed we can move on to making our designs pretty.

This is the most time consuming part of the project development process. That is why it is very important to invest time into previous steps. Spending an extra hour planning might save a week's worth of development. Technologies like databases, back-end and front-end libraries are chosen during this step. They depend on many variables such as expected number of users, what kind of operations are most likely to be involved, is the application focused on creating/editing objects, searching, presenting information or maybe all of these mentioned actions. Automation testing is added throughout the development process. It greatly improves application quality and stability. The more complex your application becomes the more changes impact the whole system. Automated tests allow the developer to catch unexpected behavior and enforce desired rules early on. By the end of the development step you will have a working application that is ready to be deployed.
