Hi Everyone,

In 2020, I dedicated 10 written posts to the ‘Prevent, Solve, or Manage Approaches’. In the first post in that series, I described the general concepts behind ‘Prevent, Solve, and Manage’. In the other nine posts, I discussed how it could be applied to areas such as:

- Health
- Crime
- Housing
- Education
- Travel, transport, and transportation
- Migration
- Money
- Environment
- Leadership

## What’s in the video?

In the video, in this post, I revisit the theory I discussed in the first post of the series. The theory is very important as it provides basis for how Prevent, Solve, or Manage approaches could be applied and how they could add value to tackling many different types of problems.

Prevent, Solve, or Manage approaches are discussed using a Venn diagram. This approach has been adopted as it is possible all three, some of the three, or just one of the three approaches could be used to tackle a problem. Generally, ‘prevent’ is prioritised over ‘solve’ and ‘solve’ is prioritised over ‘manage’. ‘Prevent’ stops the problem occurring; therefore, is generally preferred to ‘solve’, which involves removing the problem once it has arrived. ‘Solve’ is generally preferred to ‘manage’, which does not remove the problem but instead just mitigates the damage it causes. However, generally, it is better to have several approaches in place. It is possible prevention could fail. If it does, it would be good to be able to solve the problem or even just manage it.

It is important to note I have used the word ‘generally’. Each approach has a cost and a probability of success. For example, ‘solve’ could be preferred over ‘prevent’, if the cost of prevention is high and the probability of success is low. If the expected cost of prevention (probability × cost) exceeds the expected cost of solving plus the cost of the problem for the duration it takes for the problem to be solved, ‘solve’ would be a superior approach to prevention. However, combining ‘prevent’ and ‘solve’ approaches will lower the risk from detrimental effects of a problem even if not the expected cost. Other factors to consider are the certainty a problem will occur and if it is certain, how well can it be predicted to occur in advance.

Below are the main sections of the video and the timings in the video where I discuss these sections.
