It seems that in today’s workplace culture, companies looking to redesign their office space focus on copying big names like the Googles and Amazons of the world. They think that by jumping on current trend bandwagons, whether it’s beer-on-tap or relaxation pods, is enough to keep their workplaces optimized for the modern worker. It makes sense, industry leaders are smart to pay attention to how the most progressive companies are using physical and digital tools to contribute to productivity and personal fulfillment, even retention. Copying successful companies, by extension, makes it seem more likely to lead to success.

I often see companies make major decisions about offices and employees based on the “Google model,” which is what you could call an employee playground meant to inspire collaboration and creativity. However, this setup does not work for every company and could actually negatively impact ROI.

If you want to meet productivity goals (and design a workspace that supports these goals), you first need to first determine your business needs. Then, look at the data about how your employees work, and make decisions based on this data—not based solely on what Google’s doing or what’s trendy at the moment. You should understand the key collaborative relationships between employees and between teams, and what physical and digital tools employees need to succeed. It may sound simple, but some departments need to be seated next to each other, while others require isolation to be creative.

Without clearly articulated goals for collaboration and productivity, an office redesign will hit roadblocks. Your business goals should be organized and qualifiable, which is why making decisions based on data is key to achieving improved work culture and team collaboration.
