Shamsul Azhar Abbas brought about significant changes to Petronas that did not go over well with some groups. He focused on instilling good governance, competence, and a merit-based reward system. This included establishing a remuneration committee, quarterly reporting, and strengthening the board with competent individuals from the corporate sector. However, Shamsul notes that to enact real change, one cannot want the job too much, as wanting it leads people to compromise for others. He also stresses the importance of governance and competent people to ensure Petronas' long-term survival during downturns.
