Local optimisation problems

A quick note on Sam Newman's Rip It Up talk:

• Loved the bit towards the end around local optimisation problems
• risk is you could end up with 3 or 4 databases used across the department
  • comes with cost of licensing and support
  • also experience is spread too thin and makes it difficult for people to switch teams
    • there's a tradeoff between local cost and global optimisations
    • need cross cutting group to spot local trends or niche tech. Can also spot potential duplication and opportunities to standardise, could be a simple as tech leads meeting regularly
    • communities of practice and governance are two other ways
    • don't use COP for tech governance unless you want a bottom up approach
      • suits smaller organisations
