The diagram below shows the situation when a businessman works directly with a technical service provider like a software development company.
Result: Unsatisfied entrepreneur driven by WHAT the developer can do, and not what actually the business requires. The developer is focused on their technology and on only doing a fixed quantum of work (called work packet) without really thinking about the business use case or the evolving nature of the product.
The diagram below depicts the situation when a businessman employs an interface to manage the process. This interface can be their CTO or a technology consultant (IT consultant) who understands both the business and technology side of things.
RESULT: Satisfied and happy entrepreneur who gets real value for his time and money. The businessman initiatives really pay off and he/she gets a robust scalable product which is healthy and easy-to-use.
The CTO consultant advices on technology and creates a technical design in line with your business vision. He/she then can even choose the best team which suits your need, and also guide, monitor the team.
Businessmen and entrepreneurs often do not understand technology. They may have great ideas and great marketing plans. However, the lack of knowledge of the technical processes and parameters introduces inefficiencies in their product development cycle which lead to complete failure of the business idea itself.
Businessman should remain focused on the business and not software. Development companies should focus on what has to be done. The interface in the middle must manage the requirements, do the design and provide processes and guidelines to each party along with enforcing measurable performance benchmarks.
