Far too often I see misguided improvement attempts fail. I suppose if they were misguided in the first place it may be fortunate that they fail before damage is done, however too often the damage IS done, yet people pat each other on the backs and high five in the hallways on their way to picking up their bonuses.
Everyone raves about improved efficiency but often without fully understanding what the desired outcome is. I maintain that the fastest way to simply improve the speed of performing a tasks is to skip steps, but I don’t think that is the best way. Always begin with effectiveness first before making changes. What is the desired outcome? That is what matters most.
