The long-term impact of a contract-to-logic coupling will likely be restrictive and limiting. When a contract is coupled to logic, that generally means that the logic is already built. If a business’s services need to develop, it might be hard for the business to grow since the business in question is more or less bonded to the predetermined algorithm or system.
The logic, not the services, determine the trajectory, which will not bode well for a company intent on expansion. Again, it’s going to be hard to change or increase in size when wedded to prefabricated logic.
Short-term, if a company needs specific functionalities right away and isn’t worried about how those functionalities will hold up over a longer period of time, perhaps contract-to-logic has some appeal. Since all the logic is already there, a business doesn’t have to spend time or additional money fashioning its own. They can start to take advantage of the given functionalities right away.
However, the above scenario will probably be considered an outlier. Usually, the optimal coupling involves logic-to-contract so that logic is dependent on service, and not the other way around. If service comes first, that means the logic will be agile and adaptable. It can grow with the services, which is ideal for any company aiming for more than stagnation.
