The Development Speed Paradox
• Theory:
• Minimizing cycle time leads to an increase in R&D productivity?
• Re-engineering:
• Increase development speed by placing development tasks in
parallel wherever possible, minimizing development cycle time.
• Consequences:
• Increasing parallelization of development activities and the loss of
the option value1 associated with serial decision making.

The Development Speed Paradox
• Problem?
• For high risk processes – such as pharmaceutical development clearing failing or marginal molecules is more important than
reducing cycle time.
• For such high risk processes:
• The expected time to market may actually be SHORTER for the serial
process EVEN THOUGH THE CYCLE TIME is LONGER. This is the
Development Speed Paradox.
• Conversely, reducing Development Speed may increase R&D
throughput. This is the M25 Effect – after London’s orbital motorway
where speed limits were first reduced in the UK in order to increase
traffic throughput.

The M25 Effect
• Providing we build opportunities to “fail” molecules early in
the development cycle, then even though the cycle time is
longer and Development Speed slower we see an
increase in R&D productivity - the M25 Effect.
• In the example, the “Quick-Kill” organization - with an
opportunity to “eliminate” molecules after just one year –
screens more molecules, discovers more drugs, and
launches more products than the organization with the
shorter cycle time.
