A facilitated card game that lifts a team's maturity on a topic. The cards anchor the conversation and take the personal edge off it: people talk about the cards, not about each other.
A good session is one after which the team makes decisions and works more effectively. A great session is one they enjoy and want to repeat. OMG provides that: your team works through a situation (an actual or hypothetical one) in six stages on an A3 canvas (or online) with a facilitator and a deck of cards, which are carefully designed to encourage a conversation rather than supply the answers.
TalentJam or a delivery partner facilitates. The facilitator keeps time, asks questions, and does not judge, score or supply answers. A standard session runs 60 to 75 minutes with four to eight players; any manager in the room is a player like anyone else.

The first three stages resist jumping to a solution. The stages are an order of work, not a script: a Lens that breaks the diagnosis sends the team back to Understand.
Whatever the team should decide (the causes, whether the limits are real, what a choice costs) may be prompted by the cards, but working it out is the desired lift in maturity being practised.
Each domain deck carries its own Issues, Interventions and who-can-help cards, in the voice of the people who experience its issues. The shared deck of Constraints, Events, Enablers, Lenses and Dimensions works with every domain.
The Team's evaluation of well they think together in the session. A fast measure, visible within one session. Seven dimensions, each tied to the stage where it shows:
The team rates itself, with the facilitator offering observations as questions, not scores.
The Team's evaluation of their maturity addressing the focus issue(s) in their every day work, and how it has improved between sessions. A slow measure, rated collectively and revealed together: the spread of ratings drives the conversation and the group settles on a level.
Plus Don't know, perhaps suggesting an area to explore explicitly, and Not needed here where genuinely not relevant. The right level depends on the work and the risk, and don't aim for a 5 everywhere.
You can play through something that your organsiation is dealing with right now, a random scenario, or explore common scenarios for each domain set in a demonstration organisation.
The game also runs on screen, on the same A3 canvas and the same cards. A team can play a session at a laptop, watch a computer team play one through, or use it to prepare for a facilitated session. On screen, the Review shows what happened: which Interventions took hold, what the conditions did, and how the team reasoned, as observations rather than a score.

A first session on a Random Game takes about an hour. Bring four to eight people and a problem worth talking about.
