Final answer:
A well-planned and clearly communicated question should be realistic and flexible, regularly evaluated for relevance, and presented in a simple format to ensure it is achievable, remains goal-oriented, and comprehensible.
Step-by-step explanation:
The characteristics of a well-planned and clearly communicated question are multiple facets which interplay to ensure the question is understandable and actionable. Realistic and flexible questions are achievable and consider potential barriers that can be overcome, making them attainable. This means the question should align with what is realistically possible, allowing for a degree of flexibility to account for changes.
The question should also be evaluated regularly to ensure it remains relevant and continues to support the overall goals of the inquiry or research. An ongoing evaluation process allows for timely adjustments that maintain the question's appropriateness over time.
Lastly, maintaining a simple format is critical. A question presented in clear, concise terms is more likely to be understood and effectively addressed. Simplifying the format makes it easier for the respondents to grasp the intention behind the question and provide relevant, thoughtful answers.
