I will prepare myself and my time must come.

Abraham Lincoln

The railroads are in trouble today ... because they assumed themselves to be in the railroad business rather than in the transportation business. The reason they defined their industry wrong was because they were railroad-oriented instead of transportation-oriented; they were product-oriented instead of customer-oriented.

Theodore Levitt

Wie grote plannen heeft, neemt de tijd.

Sophokles

Success is just individuals who failed and didn't stop.

Gary Keller

If you call it requirements *gathering*, you're doing it wrong. Requirements are *developed*, and testing is part of that.

Karl Wiegers

Ieder meent te weten en weet toch niet; ik die niet weet meen ook niet te weten; ik lijk daarmee iets meer te weten dan hij die denkt te weten, omdat ik niet meen te weten wat ik niet weet.

Socrates

When we 'plan', we expect the actual project result to conform to that plan, and then deviations become team mistakes or sign of the team’s failure to work enough. When we 'speculate', we take the opposite perspective – it’s the plan we suspect was wrong. The plan, or speculation, is a piece of information, but it is only one piece that we will examine to determine our course of action in the next iteration.

Jim Highsmith

Het buitengewone geschiedt niet langs de gebaande, gewone weg.

Goethe

Rozen verwelken
Schepen vergaan
Dus zit niet te melken
Maar doe er wat aan.
