I have very big concerns about culture.<p>When you bring new people to a company, they tend to work the way they use to in their previous occupation. More often than not, a new employee will start his sentences with &quot;What we used to do in this situation&quot; or &quot;that&#x27;s why we did it that way at X&quot;, trying to both build up on his past experience, and to find an anchor of familiarity in an unfamiliar environment.<p>This is normal phase and usually wears off after a few weeks&#x2F;months. But for as long as it lasts, this behavior can be annoying for your current employees as they have built up their own thing, and they don&#x27;t necessarily want to be reminded that there were other options that they didn&#x27;t follow.<p>The risk that you take when bringing a team of 3 to 5 people is that they go in their own corner, dismiss all the tools that already exist, recreate the work environment they are used to, don&#x27;t mix well at all with other employees, etc.<p>And what you get from people being used to work together, you loose in management pain. I think the usual way of hiring one person, who then can refer to the good guys in his previous team is a much sounder approach, as it lets time for the culture to adapt.
