This is speculation on my part. I'm sure my colleagues will have specific examples.
In an era when competition at all costs seems to be the mantra, you lose sight of how you got to the point where you've identified a requirement, and sometimes that's through a co-development that DRDC and S&TR and DND may have developed with industry.
The irony, not only of going to competition for a requirement that you've already co-invested in, is that you may also disqualify the industrial partner you've done the co-development with because they'd find they'd be deemed to be in a conflict of interest.
Our suggestion is that the government should be deciding earlier on in its R and D phase whether it wants to establish a long-term relationship with that industrial partner that would succeed, if you like, beyond the R and D phase. And should that program go to market, it would then commit to buying from that industrial partner.
