Here's some of mine:
Put "security" before all else. Pointlessly surveil and monitor your staff for feelgood security theatre. Mandate MFA for every trivial login so that simply checking your email becomes a tedious schlep.
Spam your employees. Send out daily self-congratulatory ego-trips as "newsletters" celebrating how well the company is doing. Sap morale by reminding every lowly engineer just how insignificant they are, what huge profits the company is making and how much senior salaries are. For bonus points use a "no-reply" internal address and make it impossible to block them.
"Team build" by putting on mandatory "social" events, and various awareness and training. Shame employees to do not "participate" because that have actual work to do.
Keep zombie projects alive. Even though clients have cancelled and everyone knows it will never be delivered, keep projects running for the sake of appearances and to keep managers close to retirement in a job for another year.
Actually, stop me! This could go on all day. Someone really should write a book "How to kill a company".
