In no particular order, in this post, the author is collecting and curating all of the best tactical CustDev hacks he has come across in one evolving and growing open-source ‘playbook’.
The tactics in here are not theoretical.
These are "boots-on-the-ground, stormin’-the-beach-with-bayonets-fixed CustDev warfightin’ hacks that get the job done".
These hacks run the gamut from finding people to talk with to getting clarity in an interview to methods on validating your idea. None are always applicable, all have biases and other problems around them, but all are useful for specific tasks.
