HARMONY DecisionMaker is a new app by Goldratt Research Labs that guides you through the 5 Steps of the ProConCloud (or ChangeMatrixCloud) process to help resolve important problems or conflicts that can hang over us like dark clouds. Each of the 5 steps was designed to help prevent one of 5 most common problem solving and decision mistakes we make when resolving problems or conflicts or trying to learn from experience.

Step 1: Define YOUR Problem and why it's important.
To prevent common mistakes of Wasting our limited attention by Dealing with Unimportant Problems or Procrastinating on Important Problems

Step 2: Define YOUR and “THEIR” Conflicts
To prevent common mistakes of Jumping to a Solution Or just Finding Someone to Blame

Step 3: Resolve Change Conflicts with win:win
To prevent common mistake of FOCUSING on only ONE resolution or compromising Not realizing there are 4 viable options

Step 4: YES BUT Planning
To prevent common mistakes of Ignoring valid reservations (Yes, buts) OR Using Yes, buts as excuses not to act

Step 5: Design GOOD Experiment
To prevent the common mistake of failing to learn from experience by doing BAD Experiments when
communicating or implementing changes

Once you signup you get a free 1-month trial to test the app and functionality. Once the trial period has ended you can choose from the following subscriptions options, 1 or 12-month auto-renewable subscription or you can continue using the app just as a viewer and will not be able to edit or create new conflicts.

Information about the auto-renewable nature of the subscription:
• Payment will be charged to iTunes Account at confirmation of purchase
• Subscription automatically renews unless auto-renew is turned off at least 24-hours before the end of the current period
• The account will be charged for renewal within 24-hours prior to the end of the current period, and identify the cost of the renewal
• Subscriptions may be managed by the user and auto-renewal may be turned off by going to the user's Account Settings after purchase
• Any unused portion of a free trial period, if offered, will be forfeited when the user purchases a subscription to that publication, where applicable

Excellent app!

I had real breakthroughs completing an analysis of a wicked problem I faced for quite some time. The 5 steps of the ProConCloud process really helps one overcome self-limiting assumptions and self imposed bottlenecks.
