### What do you focus on?

• 1. l: www.linkedin.com/in/awardsounds/ t: @alanward What do you focus on? 1
• 2. l: www.linkedin.com/in/awardsounds/ t: @alanward Let’s try a question What’s 10 divided by 3? 2
• 3. You can choose from these answers 7.83214 l: www.linkedin.com/in/awardsounds/ t: @alanward 3
• 4. l: www.linkedin.com/in/awardsounds/ t: @alanward Which one did you pick? Ask yourself why you picked that one. 4
• 5. This is accuracy vs precision 7.8321 This is precise 4 This is accurate* l: www.linkedin.com/in/awardsounds/ t: @alanward 5
• 6. Most people are uncomfortable choosing 4 Depending on your rounding rules, 3 Could have been a more comfortable answer l: www.linkedin.com/in/awardsounds/ t: @alanward 6
• 7. l: www.linkedin.com/in/awardsounds/ t: @alanward But no-one… …picks 7.8321 We all know this is wrong. 7
• 8. But it has more decimal points… Wrong. 7.8321 is precise but inaccurate. Therefore it has more detail, so it must be the right answer. l: www.linkedin.com/in/awardsounds/ t: @alanward 8
• 9. l: www.linkedin.com/in/awardsounds/ t: @alanward This can be used against us. A person can provide information with a level of precision, to imply that they have done the work necessary to be that accurate. 9
• 10. l: www.linkedin.com/in/awardsounds/ t: @alanward Always value accuracy over precision 10
• 11. l: www.linkedin.com/in/awardsounds/ t: @alanward Why is it important? Too much precision early on is an indication of underlying problems 11
• 12. In the early days of any project 7.8321 Not here 4 This is where you want to be l: www.linkedin.com/in/awardsounds/ t: @alanward 12
• 13. 4 3.3 3.33 3.333 l: www.linkedin.com/in/awardsounds/ t: @alanward Start broad, but as accurate as you can be Add more detail as you progress. 13
• 14. l: www.linkedin.com/in/awardsounds/ t: @alanward If you’re starting at 7.8321 Then there’s too much detail without knowing how what you’re doing will integrate into the rest of the solution. 14
• 15. l: www.linkedin.com/in/awardsounds/ t: @alanward Risk The risk is that one part of the change* is operating at too low a level of detail. Conversations become confused. Timelines become complicated & non- deliverable. People become frustrated. * Could be organisation, portfolio, programme, project, sprint, etc 15
• 16. l: www.linkedin.com/in/awardsounds/ t: @alanward Proceed to the next level of detail together 3 3.3 3.33 3.333 16
• 17. That cylinder fits into part of a larger design that needs to accommodate its size. “But I’ve been asked to…. produce a cylinder 78.321mm diameter with a tolerance of 0.1%” l: www.linkedin.com/in/awardsounds/ t: @alanward 17
• 18. Too much detail required too quickly. “But I’ve been asked to…. produce a 12-month project plan, complete with resources & dependencies. Yet the overall design hasn’t been signed off.” l: www.linkedin.com/in/awardsounds/ t: @alanward That’s a problem. 18 It could be used for rough estimates, e.g. how much could this programme cost us?
• 19. l: www.linkedin.com/in/awardsounds/ t: @alanward Back to the original question: What do you focus on? 19
• 20. l: www.linkedin.com/in/awardsounds/ t: @alanward Always prioritise accuracy. Do as much as needed to be consistently accurate across everything you’re doing. 20
• 21. Increase precision together. Don’t go into detail in silos. Remain accurate throughout. At every level of detail. l: www.linkedin.com/in/awardsounds/ t: @alanward 21
