Keep learning.
Productivity is increased when team members have all the skills they need to succeed. If you identify someone with great enthusiasm who lacks practical skills, encourage them to take an online course or be mentored by a colleague with more expertise. Be sure your team knows that skill development is expected, and that no one should rest on their laurels. Letting employees stretch their wings and take on new and different roles creates a culture of support for learning and innovation. Have a graphic designer interested in writing copy? Give him/her a chance to brainstorm with the marketing department. A project manager with a flair for event planning? Offer the chance to be part of planning the company picnic. Small changes to roles can fuel enthusiasm.
