Why do we create interim solutions?

Typically there is some immediate problem to solve. It might be internal to the development team, some tooling that fills a gap in the tool chain. It might be external, visible to end users, such as a workaround that addresses missing functionality.

The implication of an interim solution is that it is not fully integrated into the production code, or does not follow the standards and guidelines that shaped the rest of the code. The reasons are many and varied, but the key to an interim solution's success is simple: it is useful.

Interim solutions, however, acquire inertia (or momentum, depending on your point of view). Because they are there, ultimately useful and widely accepted, there is no immediate need to do anything else. Whenever a stakeholder has to decide what action adds the most value, there will be many that are ranked higher than the update of an interim solution. Why? Because it is there, it works, and it is accepted. The only perceived downside is that it does not follow the chosen standards and guidelines — except for a few niche markets, this is not considered to be a significant force.

So the interim solution remains in place. Forever.

And if problems arise with that interim solution, it is unlikely there will be provision for an update that brings it into line with acceptable production quality. What to do? A quick interim update on that interim solution often does the job. And will most likely be well received. It exhibits the same strengths as the initial interim solution... but is now more up to date.

Is this a problem?

First of all, remember that this is a solution. It may not be your preferred solution — it is unlikely to be anybody's preferred solution — but the motivation to remove this solution is too weak.

What can we do?

  1. Avoid creating an interim solution in the first place.
  2. Change the forces that influence the decision of the project manager.
  3. Leave it as is.

Let's examine these options more closely:

  1. This does not work in most places. There is an actual problem to solve, and the standards have turned out to be too restrictive. You might spend some energy trying to change the standards. Apart from starting a tedious endeavor with possibly no positive outcome, it will only be effective for some future interim solution, not for yours.
  2. This requires that the project culture changes. This can be successful in very small projects, in particular if it's just you, and you just happen do clean the mess without asking in advance. This can also be successful if the project is such a mess that it is visibly stalled and some time for cleaning up is commonly accepted.
  3. This automatically applies if the previous option does not.

Do not fall on the dark side of cynism while trying to overcome the interim solutions you created. May god grant you the serenity to accept the things you cannot change, courage to change the things you can, and wisdom to know the difference.
