I commend you for your dedicated work to implement the portfolio optimization algorithm as part of the Defence Capability Assessment Program 2021. Your contribution in developing a linearized model for the force options selection problem, its implementation in Python and integration into the New Investments to Risked Options (NITRO) tool, enabled the successful deployment of the user interface to the portfolio designers. You effectively engaged with users and other developers and demonstrated your agility and determination in dealing with changing user requirements. Your achievements are of the highest order and in keeping with the finest traditions of Defence Science and Technology Group, and you should be justly proud of your achievements in delivering this important decision-support tool.
