Don't over-engineer solutions. Think about what you can do now.
Like focus on value, this principle is heavily focused on the prevention of waste. Waste correlates with complexity. Higher complexity means there are more opportunities for waste to creep into a system.
Focus on delivering the desired outcome, not building the most elegant and elaborate solution. Use the minimum number of steps to deliver that outcome, ensuring you are not over-processing (delivering quality above and beyond what is required).

You need to use all of your resources as effectively and efficiently as you can. This means that you should automate wherever you can, and use people only for tasks that can't be automated. It also means that you need to think carefully about what you can automate and about the circumstances where only a person will do; and about simplifying those processes you do decide to automate to eliminate wasteful or inefficient steps.
You should always optimize the work BEFORE you automate it, as automating something that is inefficient or ineffective may just result in you doing the wrong thing faster!
