40 hours a week is the most effective work schedule long term
40 hours a week is the most effective long-term. 60-h week crunches result in productivity dives after week 4. Anything over 40 hours results in a recovery period. For knowledge workers, performance declines after 35 hours, not 40.

35-40h weeks can be divided in 4x10h days + 3 free days, which may increase productivity 10-70%.

Lack of sleep is particularly damaging. Overtime kills creativity. If you're stuck with a problem, go home or take a break. Sleep substantially improves problem solving abilities.

Overtime team *feel* they're more productive, but that is false. Rest your exceptional producers.

Productivity is maximized in small teams of 4-8 people. 30-50% higher than in groups > 10. Communication cost increases dramatically in groups > 10.

Seat teams together in a closed team room. 100% increase in productivity. At least 50 sqft / person. Create side rooms for calls, meetings etc. Minimize non-team distractions.

Cross-functional teams (e.g. devs and designers) perform better. Larger breadth, less chance of groupthink. Create teams where every skill needed to solve the problem is in the room.

Schedule people at 80% capacity. The 20% goes into new idea generation and process improvement.

Allow people to prototype breakthrough solutions and pursue passions. Publicize and reward those that make it into production.

IGDA - Articles - Why Crunch Mode Doesn't Work: 6 Lessons
"Lesson One, then, is this: Productivity varies over the course of the workday, with the greatest productivity occurring in the first four to six hours. After enough hours, productivity approaches zero; eventually it becomes negative. [...]
Lesson Three is this: five-day weeks of eight-hour days maximize long-term output in every industry that has been studied over the past century. What makes us think that our industry is somehow exempt from this rule? [...] In contrast to complex mental performance, simple psychomotor performance, physical strength and endurance are unaffected by sleep deprivation. [...]
Lesson Four is this: At 60 hours per week, the loss of productivity caused by working longer hours overwhelms the extra hours worked within a couple of months. [...]"

* knowledge workers should have a 35-hour week
* optimum team size (in KW) is 4-8 people. Productivity is 30-50% higher than for groups over 10
* crunch mode gives a temporary boost, which is offset by reduced productivity during the recovery period
* seating people from the same team together (within a closed room) doubles productivity. Best bang for the buck.
* create side rooms for phone calls, meetings
* minimize non-team distractions
* cross-functional teams outperform siloed teams, more likely to generate breakthrough solutions
* every skill needed to solve the problem should be in the same room
* schedule at 80% of team capacity. The 20% great features are usually far more profitable than 100% competent features.
