The Clear Function Process

We show how we build.


This first stage is the foundation for crafting a customized solution that precisely aligns with your unique needs and goals. Our journey together begins by gaining a deeper understanding of your unique requirements. We begin every project with a free consultation where we delve deep into your current systems, objectives, requirements, and ongoing support needs.

During this stage, we will also gather and review any relevant assets or materials you may already have, such as existing code, documentation, or design concepts. Together, we will define the project scope so that the project goals and deliverables are crystal-clear. Our team is flexible and can adapt to best support your needs if the goals or requirements change.

What to expect:

  • In-depth interviews to understand your vision and challenges.
  • Collection of relevant assets and materials you may have.
  • Thorough review and analysis of your product and project plans.
  • Thorough review and analysis of your product and project plans.
  • Collaborative scope definition and refinement.
  • Ongoing support to adapt to changing requirements.


Once we have defined the project scope, we transition to the planning stage, during which we will craft a detailed project roadmap, complete with timelines, milestones, and a comprehensive quality assurance (QA) test plan. This document will be our North Star, ensuring we stay on course and meet your project objectives within the established timelines.

Your team will receive easy to understand sequence and use case diagrams based on the provided use cases and user stories. Depending on your needs, we may also produce interactive wireframes, prototypes, and mockups tailored to your project.

Simultaneously, we delve into designing the architectural framework for your solution. Like architects crafting a sturdy foundation for a skyscraper, we create a secure, structural backbone that adheres to industry best practices and ensures flexibility and scalability.

What to expect:

  • Regular meetings for clear communication and alignment.
  • Delivery of a project roadmap, including timelines and milestones.
  • A thorough review of use cases and user stories.
  • Delivery of sequence and use case diagrams for project clarity.
  • Tailored wireframes, prototypes, and mockups if needed.
  • Rigorous QA test planning for quality assurance.
  • Robust architectural framework design.


With the project roadmap in hand, our skilled team of developers roll up their sleeves to bring your vision to life. This stage is where the magic happens! With UX and architectural designs in place, our developers meticulously work to translate the design into functional code, ensuring that every detail aligns with the plan.

Simultaneously, our dedicated QA team collaborates with our engineers to ensure thorough testing throughout the build process. Testing ensures that the solution meets your requirements and our high quality and security standards.

As we progress, you can expect an open line of communication and regular updates on our progress. Our Client Experience (CX) Director will conduct check-ins to ensure that your experience with us continues to meet your expectations.

What to expect:

  • Implementation of the design into functional code with meticulous precision.
  • Rigorous testing by our dedicated QA team to ensure high-quality and secure solutions.
  • Transparent communication with regular progress updates.
  • Ongoing check-ins with our CX Director


Before we advance further, it's essential to confirm that every component works as intended. At this stage, as the name implies, we put everything to the test. Your active involvement in this phase is crucial as it guarantees that the project meets your expectations. 

We initiate User Acceptance Testing (UAT) to ensure the solution meets your requirements. We will provide your team with comprehensive test cases and checklists, covering all software requirements from the build stage. Your team will use these materials to conduct UAT testing and report their findings to our engineers for final updates.

What to expect:

  • UAT to ensure the solution adheres to your requirements.
  • Delivery of comprehensive test cases, including clear conditions, data, steps, and expected results.
  • Delivery of test checklists covering all software requirements.
  • Meticulous testing to guarantee functionality, quality, and security of your software solution or application.


The time has come to go live with your solution! This stage marks the transition from development to implementation. We will be with you every step of the way to ensure a successful launch.

Our carefully coordinated release process ensures a smooth, worry-free rollout of your software or application. At this stage your team will recieve comprehensive software documentation to facilitate the management of your systems moving forward.

But we don't stop there. We offer guidance, coaching, and team building sessions to help you bring your processes in-house, mitigating future costs and ensuring your team's autonomy. Our ultimate objective is for you to become self-sufficient, allowing your business to continue thriving without needing external development teams.

What to expect:

  • A coordinated 'Release' process for a smooth software rollout.
  • Comprehensive software documentation to support independent system management.
  • Guidance, coaching, and team building sessions to empower your team.
  • A focus on self-sufficiency to reduce dependency on external development teams.


We will be here to lend a hand if you require additional support beyond the initial deployment. We will work together to identify measurable iterations, including addressing bug fixes, implementing software updates, and exploring software enhancements.

You will receive progress updates and invitations for feedback throughout this process. Your feedback is crucial to ensuring we continually refine and improve your solution. Our collaborative approach ensures that our work align with your evolving needs and priorities.

What to expect:

  • Ongoing support for bug fixes, software updates, and enhancements.
  • Regular progress updates.
  • Refinement and improvements based on your feedback.
  • Continuous evolution of your software.
