Acting as a team lead I feel the engagement in our sprint planning session is low.
Some people are very comfortable to talk and share ideas/knowledge in order to help the team to define tasks for our stories, but some people (usually more then half of the team) simply left the meeting without even speak out once.
The team have about 10 members and they are working under the Disciplined Agile Delivery guide.
It could be many things and it's unlikely that the 5+ out of 10 have the same reason for not speaking. With such a small team you can get to know their personalities and how they behave outside the meeting. This will help guide you to a solution.
If the lack of motivation is macro (the team is affected all the time, not just during this meeting), it will also be the hardest to solve. Causes can be wide ranging, but consider adding side projects, reward systems and acknowledgements.
If the lack of motivation is micro (only related to this meeting) you may need to 'shock the system' by scrapping your meeting. Don't just reschedule the same recurring meeting in Outlook. Cancel it. Create a new one. Change the day, call it something else and change how you run it. Oh, and keep it short.
Create a process where everybody gets a turn. Go Round-Robin or Alphabetical or simply call out names.
You can also pre-meet with a smaller group before meeting with the full group. You can then "contribute on their behalf" by referencing back to the smaller group meeting. "I talked with Bob earlier and...".
Before the meeting, give a specific task to a specific member. This will give them something specific to contribute and make them the 'expert' for answering questions. This works good when you already know the answer because you can guide them as they answer questions. For example:
"We need some options for logging exceptions. Take 30-min and look into X, Y and Z and see if you think they'd work. See how much they cost and if we can log errors to a central location.".
Then, during the meeting you can ask them direct questions:
"Do any of those allow central logging? Are any of them expensive?"
Ten is a large group. Have you thought about spending part of the meeting working in smaller groups? For example, you could divide the team into pairs and hand out tickets to do initial planning, then combine into 2 groups of 5 to review&revise the initial plans.
Techniques that pull input from each team member silently might also help. For example, if you started the meeting by handing out tickets and packs of sticky notes, and had each person silently do the task breakdown on stickies in a short timebox. Then go round the room & have each person present the initial plan for that ticket, explaining their reasoning as they put the stickies up on the board, and updating as the group discusses.
Pay attention also to interpersonal and personality issues. Among the many possible issues are:
Good luck! (And welcome to pm.stackexchange!)
Simply start by an ice-breaker (one site proposing a few : https://www.icebreakers.ws/good-icebreakers-by-name ), people will start to interact with each others, so you will understand who is shy, and who is just uninterested. One ice breaker that you can repeat each time and that I really like and that motivate with just one sentence is : "ok for this meeting what super power are you bringing" (requesting to change it each meeting). Good luck, and just publish feed back if you tryed the idea.
