An important factor to consider with open plan design is osmosis: that is, how people learn just by being around the knowledge. This allows newer staff to learn from the more experienced team members & gain knowledge faster. You can see in examples in wildlife, the adult will teach the younger ones how to hunt etc. In the workplace, the inexperienced observe & learn by being part of it. You might have a senior salesperson, or a very experienced consultant, and around them you have people that are less experienced where they can hear and observe the reactions. This allows the process of osmosis, and they are able to use the senior staffers wording & skills. They can hear great ways to problem solve, and ways of responding to clients that assist to de-escalate & provide solutions. They are learning all these skills by person to person rather than books; you learn far more from people than you do from books. Those interactions are real time – not separated by a half second Zoom VC delay. These are crucial training techniques business would lose if the idea of abandoning an office was taken on. You would lose the ability for the organisation to grow & develop – apart from formal training courses. Osmosis encourages the oncoming generation, the idea of renewal, where team members progress through the organisation by mixing with people that are ahead of them & sometimes overtake them! But this takes a team environment that only a physical workplace can bring.
