Problem-Solving for Software Engineers
I get tasked with things outside my immediate knowledge bank all the time.
My goto solution tree is similar;
Do I understand the end goal?
No? - converse until so
Sell yourself as an innovator as opposed to a guru.
What is it similar to?
What are some specific tools that will be used?
Watch videos on those tools.(as they may cover the desired project indirectly)
Bid high enough for 2 attempts (or 1 attempt and specialty tools)
Be open to "breaking even" on time in exchange for experience.
27 years of that later, I have a shop full of trade tools and the expertise and experience to sell competent service in multiple fields.
