Here's my samples of documentation activities that helps in designing and documenting the processes.

Creating Process Flow Chart with the usage of Microsoft Visio. This is a type of documenting the process thru creating the visual high level process flow to make it easier how the job started and ended. This is also helpful in identifying gaps, process improvement in eliminating waste in steps and faster endorsement.

Creating Work Instruction to document the detailed steps by steps procedure to perform the specific task or activities.

Creating Standard Operating Procedure (SOP) which is aligned on Organization's requirement. It is the comprehensive document for the set of instructions and guidelines also the responsible person indicated for this process.
