Keep using what YOU find most effective to gather information, share insights and gain consensus!
A3 Thinker's virtual cards will help you overcome any initial block and prompt you with the right questions when you need them most.

"It's like working side-by-side with a sensei on the production floor."

Use A3 Thinker to frame problems with improved clarity, accuracy, precision, relevance, depth, breadth, logic, and significance.
Choose a section in your report that needs work, read one or more relevant cards and be prepared to be stimulated and challenged!

With its focused questions, A3 Thinker will help you expand your circle of influence and engage teams and co-workers in efficient problem-solving conversations.

For: Managers, teams, change agents, coaches, entrepreneurs, and anyone else who'd like to systematically solve problems and move from where they are to where they need to be.

A3 Thinker is a versatile tool that can be used in conjunction with books or typical problem-solving classroom training.
More importantly, it can help you well AFTER the "feel good" effect of the training has faded away and you face your most crucial problems in your workplace and personal life.
A3 Thinker's critical thinking and Socratic questioning cards will help you eradicate problems, develop new and existing reports, facilitate and mentor.

It keeps you in line and focused. As long as you don't expect to be an A3 thinking master in no time ;)

I downloaded this app the day it was released and I was already using it at work the following day. A3 is a Lean technique for understanding situations and problems, finding the deep root causes, identifying and validating counter-measures. A3 Thinking is a method for improving capabilities of organizations on an ongoing basis by finding the right problems to solve and solving them systematically with the help of A3. I've been using the A3 Thinker app in two different modes. In larger group meetings, when the goal is e.g. to grasp the current condition, identify and state the problem or do the five-whys analysis, I usually only glanced for time to time at my iPad to keep the conversation focused on the particular part of A3 that we're working on. Before such meetings, I also flipped through the 65 cards to jog my memory. Card 19 about the problem scope was fresh in my memory during my very first meeting using this app and it saved the remaining half of the conversation. In smaller meetings (up to three people) or when working by myself, I looked at A3 Thinker more closely and reviewed the cards more often to improve the clarity of what was being added to the A3. My work this week included investigating a complex incident with A3 (so far, 22 people from five departments contributed to it) and we're basically at a point where counter-measures are suggesting themselves. People are starting to appreciate the power of the A3 technique and the potential of the A3 Thinking method for organizational improvement. Helped by this A3 Thinker app.
