The BrillMark Process
1. DISCOVERY
Website experimentation starts with auditing your website to identify critical areas and then creating improvement strategies to be tested against the control. This can be done by a CRO agency or your own in-house team. Once you have your testing requirements in place, it’s time for BrillMark to take over.
2. TECHNICAL DESIGN
Our role starts when you decide what are the requirements and parameters for your website experiment. Our experts will design a technical specification for the proposed test, asses the approximate number of hours required, and send you an estimated quote for your approval.
3. DEVELOPMENT & QA
Once the technical specification has been approved, our team will develop the test locally, move the test to testing platform of your choice, and apply the optimal platform-specific settings afterwards. Next, the developed test is sent to our quality assurance department for rigorous review, and once test acceptance criteria is finalized, and the test is sent to you for final approval.
4. DEPLOYMENT
Once you’ve reviewed and approved the developed test, it’s time to go live! We will monitor the tests closely for 24 to 48 hours to ensure that the test is performing as designed and that all goals and metrics are being tracked correctly.
