There is automatic version control and all history is saved.
You can revisit the strategy at any time and make simple corrections.
Any correction inevitably has a number of consequences that can be extremely complex to understand.
With MakeMyStrategy™ you click on "Create new version", select the topic you want to correct and then you will be shown where the correction will have consequences and where you need to reconsider. Once you have corrected the consequences, you can generate an updated strategy plan with updated output with just one click.
The new version is saved with the unique name you set and the date.
