Tips for Asking Good Questions 

i) be clear while being genuine and respectful (always ask questions in a respectful and considerate manner as this demonstrates your respect for others; ask questions out of genuine curiosity rather than to show off and/or put others on the spot, ie
"...Sincere questions show you care about them and the topic and you're open to learning from them. Frame your questions clearly and concisely. Avoid ambiguity to ensure that your team understands the purpose and context. Allow silence after asking a question. As silence can create time to think. Don't rush to fill silence with your words. Silence can be uncomfortable, but it can also be productive. It can signal respect, interest, and anticipation. It can also stimulate creativity and insight ..."

ii) contextualise your approach (this means
"...Tailor your questions to the individual and the situation. Consider their background, personality, preferences, goals, and the purpose of your questions. Timing matters, too. Some enquiries are best suited for team meetings, while others may be more appropriate in one-on-one discussions. Adapt your approach to the situation..."
Michelle Gibbings, 2023p)
NB Need to ensure that your questions are essential, relevant and adding value the conversation; focus on quality, not quantity.)

iii) use open-ended questions (this will encourage detailed responses and promote meaningful discussions; these questions often begin with 'how', 'what', 'why', 'tell me more', etc
"...invite your team members to share their thoughts, feelings and experiences without limiting them to a yes or no answer..."
Michelle Gibbings, 2023p
Be conscious of how you word and phrase questions, ie avoid leading others to a specific answer.
Rather than asking, 'Don't you think you should implement this new strategy?' ask them 'What are your thoughts on the proposed strategy, and how might it impact your goals?')

iv) follow-up and clarify (use active listening, ie this
"...involves paying attention, paraphrasing, reflecting, summarising, and asking clarifying questions. It also involves avoiding distractions, interruptions, and judgements..."
Michelle Gibbings, 2023p
Ask thoughtful follow-up questions based on previous questions and/or responses; explore the underlying issues, motivations, implications, challenges, opportunities, etc:
"...show you're engaged, want to learn more and demonstrate your interest in understanding the person, not just hearing them..."
Michelle Gibbings, 2023p

Rather than asking 'What are the main challenges you are facing now?', ask them 'What support do you need to overcome these challenges?')
Clarify questions by checking for accuracy, completeness and agreement; this reduces the chance of misunderstanding, errors and unnecessary complexity.
Use phrases like
"...'Is it....?', 'are you...?', 'do you mean....?'. Then asked the person to confirm, explain, or elaborate on something they have said.......'can you elaborate?, I want to make sure I understand your perspective fully..."
Michelle Gibbings, 2023p

"...use reflective questions to encourage self-awareness and personal growth. Thoughtful questions help your team members explain their thoughts, feelings, actions, and outcomes. Good reflective questions elevate learning and progress by asking the person to evaluate, analyse, reflect on something they did or learned..."
Michelle Gibbings, 2023p)

v) encourage divergent thinking (ask questions that challenge the status quo and encourage different, creative thinking; some useful starter phrases include 'what if', 'how might', 'imagine', etc, ie invite people to explore possibilities, alternatives, etc; encourage exploring different perspectives; can we do things differently?.
Rather than asking 'how can we improve our current product/services?', ask 'how can technology change our products/ services?')

vi) be receptive to feedback (this is part of self-reflection, ie reflect on your questions' effectiveness by considering their impact, ie did your questions generate good discussion, uncover important issues, etc.)

Summary
When you embrace the art of constructive questioning, you challenge the assumptions, beliefs, etc in status quo thinking.
"...When you embrace the power of curiosity and what comes when you explore and discern rather than assume and accept..."
