My two cents

Here are three reasons that can lead to the redesign of a service or product:

When you create a new service, it has one purpose, and it's structured in a very clear way. It's very efficient.

And with the years, as it evolves, it grows, changes, and develops. And maybe it has changed drastically three or four times.

This can lead to a service feeling like a bit of a Frankenstein.

It's then made of different pieces that don't fit. Absolutely well together, but still, it does the job.

It can do too many things. It can be too complex for the people who use it or too complex for those who have to manage it. And it might have lost his focus.

When you feel your service is like a Frankenstein, that's a good moment to think about the redesign.

A good service should be viable, feasible, and also desirable.

When your service isn't viable anymore, it means that it doesn't make enough money for the service to be run. Or maybe your service isn't desirable anymore for the people it wants to serve. Because trends change, people change, and expectations change too.

Or your service isn't feasible anymore. It takes too much energy, money or resources to make it happen.

Whenever the balance between viability feasibility and desirability is broken, it's a good moment to think if you should do a re-design.

Sometimes a service works perfectly well, but you still want to change it completely.

This is something that happens for services that are within a company where the strategy has changed. As there is a new strategy, the service has to change and adapt to serve that new strategy.

So it can be helpful to think about a redesign of your service or your product when you are either in Frankenstein mode. Or you feel that the three aspects of desirability, feasibility, and desirability are broken. Or the company where the service sits has a new and completely different strategy.
