QA Venn Skillset Maps

I would like to share with you this little trick.

I use it every time when I need to find out, how hard it would be to learn something new. You can use it for yourself or for your team members. There are a lot of situations when you may need it, for instance:
-- you are building a matrix of competence, 

-- or calculating the team capacity,

-- you are thinking about taking a different a job, 

-- or starting a new project and not sure if you are up to it,

-- or maybe you are hiring someone and need to assess their skillset.

Average QA expertise can be represented as a Venn-like diagram. As you can see, it consists of three major parts:

• skills related to the test itself (QA): such as QA theory, certain cognitive skills, decision making skills, logic in a broader sense;
• tools-related skillset (Tools): knowing our tools, whatever they are, from test management systems to programming languages;
• knowledge of the domain (Domain): dark secrets of this particular trade, be it banking, telecommunication or IOT.
