We were asked to estimate the cost of the overhaul of interactive models used during certified accounting courses. Models were demonstrating the specific money-flow that accountants in the UK must know by heart and have a deep understanding of it in order to provide professional services. The models were heavily outdated, hardcoded and each of them was a separate entity. Editing them was hard and time-consuming and would result in a significant cost for the client. As they were built using Flash, it was uncertain at that point, until when it will be supported. We provided the client with a ball-park estimation and development plan.
Visuality delivered a high-quality product. They were quick to communicate and address any issues that arose, and their effective project management ensured team focus and coordination. Friendly and professional, Visuality was responsive to needs with solutions and actions.
We demonstrated the new prototype of the engine to the client and we got a green-light to continue the research and design phase, this time with the client’s direct engagement. As the client was an expert in accounting and an efficient mathematician, he helped us to write the mathematical formulas that were being converted into JSON files. Such files were then inserted in the engine and as a result, we could observe running calculations demonstrating complex money flows that occur in the UK.
After the workshops, we prepared a DoR document, user-stories and a precise estimation that considered all possible scenarios. The client decided to build a complete model that would be the base for the development of the rest of the interactive models. We used the know-how gained during the prototype engine development, therefore we were able to deliver the first model in a relatively short time. When delivered, the client tested it with the students and decided to build the next models. This time the process was even less time-consuming as new models were based on the first one.
