Spaces that encourage teamworkA few simple steps can create a work environment that enhances the collaborative workstyle so much in vogue for white-collar professionals, says Harvard Business Review.Business today requires collaboration, but we rarely design our workspaces to support this.Here are three ways your company can restructure your office to better support people working together.1. Vary the types of workspaces. Employees need group spaces for co-creation, but there should also be areas for concentrated work (unassigned individual workstations), emergent social exchange (free-flowing hallways), and learning (rooms equipped with technology and tools).2. Provide the right tools. Make sure meeting rooms include tools like whiteboards that allow employees to record ideas and create a visual, side-by-side review of alternative solutions.3. Give project teams a dedicated space. Returning to the same workspace each day, keeping meeting notes on the board, and leaving work on tables between meetings can help teammates maintain a shared mindset, sharpening their focus and speeding up the collaborative process.Incentivise your salespeopleDefining and implementing the proper incentives is the key to getting the most out of your sales force.A few progressive companies have been able to coax better performance from their teams by treating their sales force like a portfolio of investments that require different levels and kinds of attention. Here are some ideas:1. Get rid of commission ceilings. Caps on commissions incentivise salespeople to sell to the quota and then stop. Without them, you'll likely see increased revenue and happier salespeople.2. Offer overachievement commissions. For those who surpass their quotas, increase the commission rate. This will keep your stars working hard during the fourth quarter, which is often when customers are most ready to buy.3. Allow multiple winners. This will boost sales effort and improve performance better than contests with winner-take-all prize structures.
