Why the partner decision outweighs the platform decision
By the time an implementation partner is being selected, the platform shortlist has usually collapsed to one or two viable options whose core capabilities overlap heavily. What still varies enormously is what happens next: whether the data model matches how your organisation actually sells, whether salespeople adopt the system or work around it, and whether the configuration you get can survive three years of platform upgrades. All of that is partner work. Buyers who spent months on platform evaluation and days on partner selection have the ratio backwards.
