Patterns

Patterns - well known problem - solution pairs. They are good to solve the common problems - only if the problem exists.

The designers tend to get carried away by the patterns and apply different patterns to the general templates only to complicate the design. Sometimes over applying the pattern results in performance and maintainability issues to the solution rather than solving the problem.

So, I know the common solution so I will create the common problem.

Even in solutioning a consultant tend to have certain patterns and provides solutions using those patterns. This should be only applied after careful thought process, considering all other parameters of solution being same.

Each business situation will have its own Uniqueness - So, be careful when applying the past knowledge (pattern) while providing solutions.
