Cost Savings Example • You have a call centre with 100 staff. The run rate of
each person is on average £30,000pa. • Project Optimise will streamline some of the services
allowing for a reduction in calls, allowing for a reduction in 5 less staff in the call centre.
• What is the Cost of Delay of not delivering Project Optimise?

Increase Profit Example • You need a CRM to allow an increase of sales of
£100,000 a month. • Vendor A costs £50,000 and has a eight week
integration period. • Vendor B costs £100,000 and has a four week
integration period. • Assuming they both have the same functionality,
which vendor would you choose and why?
Lets try a more real world example Have your smartphones at the ready to do any research you think might help you to make assumptions
Local Alarms Ltd • You are a small building security alarm installers and
maintainers covering the local area. • Your accreditation of Acme Secure products runs out soon.
Acme are encouraging you to also certify for Acme Phantom!
• Phantom! is a larger system for larger properties, thus making it possible to charge more for install/service per hour and by it’s nature takes longer also, so margin and average invoices would be higher.
• If you do not renew your certification, Acme will stop sending leads to you and stop you validating warranties.
• You feel you can accommodate this additional work for Phantom! within the existing workforce.
Why use Cost of Delay? • Results in better Return on Investment through better
decision making. • Allows for an adult conversation about the benefits. • Surfaces assumptions, as each value in your
calculation will have an assumption. • Allows for risks in assumptions to be tested before
you start work. • Allows you to guide a conversation about
prioritisation, not drive it.

different team, different calculation.
