- competencies (education, qualifications and areas of knowledge - bricklaying, plumbing, electrical work, roofing, carpentry etc)
- cost
- work ethic (turns up on time, is diligent and doesn't leave a job half done, honesty
- how quickly they get the job done
- customer relationship management (how much they keep me informed about the costs and what they are doing)

Use the following statement as a guide to this thinking "being able to do building work doesn't make you a competent builder". Most people can run (to some degree), this doesn't make them competent runners, that competency comes from training, eating well and plenty of sleep.
Defining a capability is an extensive task but once done can lead to a major simplification in the overall understanding and modelling of a problem domain. Consider the following example, you you want to build a home from scratch, core required capabilities
- architecture
- building services (described above)
- garden landscaping
