Risk & Mitigation Risk Consequence Development effort fails. ESS specific equipment can not achieve required performance levels. • • Development activities are slowed due to resource bleed to construction projects • Difficulties arising from inkind arrangements delay or disrupt in-house activities. • The serviceability requirements of the facility are not achieved • • Probability Mitigation / Impact The functionality or Moderate / performance of High instruments are degraded. Instrument concept is no longer viable. • • Manage expectations Prioritize critical aspects of development Start early with staged deliverables Design in stretch Prioritize critical issues, start early and • stage deliverables • The delivery of technologies is delayed. The construction of instruments is delayed. High / Moderate • Separate development and construction activities & personnel The delivery of technologies is delayed. The construction of instruments is delayed. High / Moderate • Reduce exposure of critical projects to risks of in-kind. Devote effort to well define contracts & Start early • Prioritize issues during development of equipment Prioritize issues during design of instrument Start early & stage targets Ring fence development activities Organization for in-kind activities • must be settled early on Instrument breakdown High / Low frequency increases (High during reducing availability. op’s) The operating cost of suite increases Consider facility objectives from • start of development •
