If we are so knowledgeable, why is mediocrity omnipresent? If we consider titles, certifications and fancy tools, why do we still get more project failures than successes? Take a look at your own backyard — how are things going on there? Are projects on time / on budget? Are processes continuously measured and improved? Are you innovating? Does your company know what it knows?
You don’t need much to become better than the average.
