- Use the 20/80 rule
20% Perfection will lead you to 80% of your costs. Customers might not be willing to pay for another 80% perfection. - Manage time
Don't lose yourself in details, respect your customer's urgency. - Focus on your goal/target
Don't take too many side steps. - Don't be obsessive
Trivialities can become far too important. This distracts the attention from the bigger picture. It is costly and frustrating progress. - Think comparative
Don't do everything yourself. Sometimes, others might be slightly cheaper or faster.
