There are five $(5)$ Pillars in the public procurement process which are part of a system that is in accordance with fair, equitable, transparent, competitive and cost$-$effectiveness in government procurement in the supply chain. With these five $(5)$ pillars in mind, read the below extract and answer the question that follows:

$$Reeling from recent revelations on a corrupt tender that saw R$620$ million being wasted on unsuitable locomotives, the beleaguered Passenger Rail Agency of South Africa $($PRASA$)$ has been coming off its rails, Solidarity said.

The public protector found that $($ex$-$CEO Lucky$)$ Montana was responsible for large$-$scale maladministration, abuse of power and wasteful expenditure during his tenure at Prasa.$$

State which two $(2)$ pillars you believe were in breach and justify your answer. NOTE: You are required to provide each pillar with its justification.
