What Happens After a Deal is Signed

Team Formation and Kickoff

InApp’s software development process starts with team formation and project kickoff. Your team will fit your needs, and typically includes software developers, testers, and a business analyst (when needed). The project manager will be responsible for ensuring that the team works together effectively and efficiently to meet your project objectives.


The project planning phase typically includes the development of a project charter, which is a document that outlines the scope, objectives, R&D, change management plan, risk management plan, QA plan, and timeline for the project. The project charter is used to guide the project team and stakeholders during the execution of the project.

Architecture & Design

The architecture and design phase is a critical part of the software development lifecycle. During this phase, the team defines the overall structure of the software system and how it will work. At InApp, the architecture and design phase happens under the direct supervision of our Technology Management Office (TMO). The TMO is responsible for ensuring that the architecture and design of a software development project are up to standard.


This is the stage when the code for the application is actually written. This is usually preceded by a period of planning and design, and followed by a period of testing and deployment. Our pool of experienced developers have a “bag of tricks” that they can draw upon to solve problems quickly and efficiently. This can make the difference between a successful project and one that fails to meet its goals.

The testing and quality assurance stage in a software development lifecycle is critical to ensuring the quality of the final product. This stage includes a variety of activities that begin at the start of a project from verifying requirements to unit tests, integration tests, performance tests, stress tests, and security tests.

Maintenance & Updates

The delivery stage is the final stage in a software development lifecycle. It is when the software is delivered to the customer or client. This stage involves authoring help documentation, beta testing, final testing, and rollout.



The maintenance stage is one of the most important stages, as it ensures that the software continues to function properly and is up to date. This is the stage where developers work on fixing bugs, adding new features, and improving the overall performance of the software.
