All 5 components of the SPACE framework need to work together! You can't have one without the other.
Many times, variety is key.
Not every PD must include all 5 areas; however, think about these things when choosing PD for yourself or your school. These aspects can be cultivated within your school, if the PD doesn't include something outright.
How will you apply SPACE to this very conference?
I developed SPACE as part of a presentation I did for ISACS 2016. Check out that presentation, which contains many links for "tools in space" here:
