1. Colour Modelling Modelling with the 3rd dimension by Doug English Co-founder & Head of Engineering @ Culture Amp

2. Object Oriented Modelling asks us to focus on ‘real world objects’ Aeroplane Passenger Airport Flight Plan

7. Mentored by Jeff De Luca
 (Architect of Feature Driven Development) Consulted as a Domain Modeller with large scale industry models (eg IFW, OFX)
 at multinationals (NAB, ANZ) 5 years of experience applying and adapting my learnings to startups my background
8. Don’t try and model the “entire” domain. Model only what your solution needs to care about. You can’t model a domain you don’t understand. 
 It’s critical to work hand-in-hand with domain experts!! Your domain model must be the share language between all stakeholders - and used to name classes in the code!! what I’ve learned
9. Colour Modelling categorises everything into one of 4 archetypes << party, place, thing >> << description >> << moment-interval >> << role >> Description Moment- Interval Role << description >> << moment-interval >> << role >> Party, Place, Thing << party, place, thing >> (They’re all ‘real world’ just some are ‘concepts’, not ‘objects’)
10. << party, place, thing >> << description >> << moment-interval >> << role >> Description Moment- Interval Role 0.. * 1 0.. 1 0.. * 1 1 << description >> << moment-interval >> << role >> Party, Place, Thing << party, place, thing >> that tend to connect consistently
