Some relationship counsellors suggest cohabitation first - or, in business terms, a strategic alliance, which provides a way to dip a toe in the water. But research by Boston Consulting indicates that loose arrangments are just as hard to manage and frequently fail. Surprisingly, marriages that follow a period of cohabitation are even more likely to fail, perhaps because of the difficulty of shifting gear from a low-commitment relationship to something deeper. Which is interesting but not very useful if you're looking for a constructive model for growth.
So if neither marriage nor cohabitation offers much other than a warning sign, where should we look next? Maybe polygamy is a better means by which to expand the family unit. Johnson & Johnson, one of the most profitable companies in the world, has never undertaken a major merger, preferring instead to acquire smaller businesses and nurture them rather than absorb them. Its success over 100 years would suggest that this form of getting it on provides a more reliable model for sustainable value creation. We don't recommend that you apply the same rationale to your home life. Unless you live in Salt Lake City.
