Rough Order of Magnitude – Your Time Has Come explores the critical role of early-stage estimation in decision-making, innovation, and strategic planning. In an era defined by uncertainty and rapid change, the Rough Order of Magnitude (ROM) approach—often dismissed as imprecise or overly simplistic—finds new relevance. ROM is a powerful tool for navigating ambiguity, enabling stakeholders to act decisively with limited data. It challenges the obsession with precision in the face of incomplete information, arguing instead for the pragmatism, speed, and directional clarity that a ROM provides. Drawing case studies, this presentation champions ROM as a mindset shift, empowering individuals and organisations to move forward when perfect knowledge is out of reach.

As an Executive Director with Synergy Group, I am pleased to be part of a team providing quality services to Government. I have 9 years Industry experience in the Banking, Insurance and Electricity sectors, followed by over 25 years’ experience in the Government sector. Before joining Synergy in September 2018, I led a team implementing major reform in Project Controls (Cost Estimation and Forecasting, Schedule Management, Risk Management and Workforce Planning and Estimation) for a large Government department. As a leader, I believe in being a positive advocate for my team, enabling their success in delivery, and also encouraging their personal development. The work we do is very important, but the people are more important.

I am proud to support the professionalisation of project controls through my role as a Director of the Program Governance and Controls Symposium (PGCS), as the President of the ICEAA Canberra Chapter, and a vocal supporter of, and participant in the Project Controls Expo.

Together with my husband, I also successfully breed and exhibit purebred Bullmastiffs (GrizzMuffley Bullmastiffs https://www.facebook.com/grizzmuffley.bullmastiffs).
