So you can either work staff really hard to get a project out and then accept an unproductive time to follow, or you can accept a more average effort over a longer period.
Personally the hardest mix is 9-5 of regular work and then having to come up with inspirational ideas and solutions. This keeps me up all night and burns me out.
This 150% nonsense sounds like trying screw an extra bit of work out of your staff in terms of innovation, without giving them the space to think.
