Checklists work in a complicated world like a charm. You have to make sure to decipher between complex and complicated. If you’re dealing with routine tasks and processes where you do know what “high quality” means and how to solve a problem in a repeatable manner then checklists really rock.
And yes, agile organizations face such complicated problems all the time as well. They need to create invoices. They need to do bookkeeping. They need to do administrative work. The onboard employees. They onboard new customers. They do marketing with customers. They do content marketing. The list goes on …
It’s not really a question if you’re agile or not. It’s rather: Does your organization have the courage and willpower to establish and adhere to checklists where they can shine.
