"Heinrich was able to demonstrate very clear thinking around what the strengths of our current squad are and what needed to be done with each of them individually in each of the formats.
"He cleary demonstrated that he'd done a lot of homework on what we needed to be doing and then presented a plan as to how we could go out and perform and be successful."
Wicketkeeper Kruger van Wyk, who was briefly a team-mate of Malan's, South African-born batsman Carl Cachopa and How all tapped into their own networks, as CD sought to see if Malan stacked up.
"Everyone spoke very highly of him...and the feedback was all very consistent," said Henderson.
Henderson said previous CD coaches have been asked to do the virtually impossible, which had contributed to the relatively high attrition rate. But Malan will not be convener of selectors, nor have any talent-spotting and coaching responsibilities across CD's eight districts.
He will concentrate solely on cricket and the Stags, leaving people like manager Lance Hamilton and director of cricket Craig Ross to deal with all the off-the-park stuff. Malan will also be supported by specialist skills coaches Shane Bond, Mark Greatbatch and Mike Shrimpton, as well as psychologist Gary Hermansson.
From a playing perspective, Henderson said "if he was a betting man" he'd take a punt on the Stags retaining all of last summer's squad.
