Motivate your team with “Why.”

One of the challenges most of the managers/leaders have today is to keep the team motivated towards their work. Many factors are contributing to people motivational level, and there is no single universal solution which caters to all people’s motivation problem. One of the solutions, as a leader/manager, you can inspire the team is through your communication about their work, effort , contribution to result.

For example, the person has to be communicated why his work is important to the organization in terms his contribution to the organization’s wellness. (Instead of merely explaining his job description of what and how part)

Similarly, when you are asking for some information, you can communicate why this information helps you will motivate them to add value in their working rather than just asking for a report.
Likewise, when you are initiating any new changes, tell them why this initiative is important for them and their role on the result.

Personally, it is working well for me when I work mostly on project based environment where just dictating won’t work.
People are relatively inspired if they knew the purpose of their work and inclined to put extra effort when they know their work can add value to the others. 

Be aware your communication process by explaining WHY part and test it yourself with your team. It may initially require patience and ego aversion . Once you practice, whenever you communicate, you tend to explain with WHY part, and it likely improves the motivation level.
