Documenting resolves these key issues

Sudden loss of a key employee

When a key employee leaves after being with you for many years, here's what could leave with them:

customer trust, including understanding each customer's unique personality and how best to serve their needs
the detailed knowledge of how things are really done in their position
their ability to quickly, efficiently and effectively resolve problems
their ability to confidently, competently and quickly make decisions
their internal capital - how much the team relies on their knowledge and support
their ability to train new employees
your deep trust in them to execute without requiring your time and input
their direct or indirect impact on growth
their impact on smooth running operations

This employee may also be someone who performs a ton of tasks as your company, that only they know how to do.

Capturing as much of this knowledge capital now will bring incalculable relief when that key team member departs.

New hires not contributing quickly or effectively

Your company requires the need to hire new employees frequently and it's taking them too much time to get up to speed in your view.

Documenting the processes & procedures they will be performing will absolutely reduce the time from onboarding to a productive contributor, while giving them the very resources they need to be competent in their role.

Operations not producing desired outcomes

The company is not performing consistently in a few or several areas, causing a negative impact to the company financially, in productivity, quality, etc.

Improving consistency requires improving efficiency. Documenting every step of your processes & SOPs will absolutely move you in the direction to resolving this.

You - the Owner - pulled into day to day operations

You are far more an employee owner, instead of the chief growth architect of your company.

Your company is suffering in several areas because you don't have the time to focus on leading it.

Documenting then delegating the processes and SOPs you find yourself continually doing, whatever the reason, is a must if you want to free up time to focus on running and growing your company.

You want to scale....or sell the company

You cannot scale if you don't document your processes & procedures. No wiggle room for compromise here.

If you want to maximize value for your company, documenting an absolute must do.

You want to incorporate AI - effectively

Another common sense solution here: don't attempt to optimize or automate a processes that's not fully understood.

First document it so you clearly know what you have and how it works. Then incorporate AI to optimize it.
