Innovation is not a solo activity, but a collective effort. It requires collaboration among team members, as well as with other stakeholders, such as customers, partners, and experts. Collaboration enables sharing of ideas, knowledge, and feedback, and enhances creativity, quality, and efficiency. To encourage collaboration, you need to build trust and rapport among your team members, and foster a sense of belonging and purpose. You also need to facilitate communication, coordination, and cooperation, and use tools and platforms that enable collaboration.
