I was yesterday confronted with a conversation about how something that I was doing with a client was wrong.
A little confused about how something that was going wrong was producing such good results we started to double check a couple of items.
After a few minutes of scratching our heads it turns out that 'wrong' was a perspective. There were many appropriate solutions, but the other person only saw one as being the right solution.
After a little bit more digging it turned out that my client had wasted a couple of weeks of their improvement efforts on trying to work out what was wrong with what they had already done!
Continuous Improvement is rarely a straight-line affair. It involves experimentation and one team will create a different solution to a different team.
It is the direction of travel that is the important factor to agree upon.
