How do you Feel faults should be viewed, if the Firm is always to proactively aid innovation and change?

A design might not converge or healthy perfectly as it will not suit the info, or if you like the information You should not fit the product. It can be quite difficult to advise on these types of scenarios, especially if presented frequently.
