Having a plan is always handy. It helps you get the job done and makes you look tidy in front of others, and a good impression is made. When the recruiter asks you this question, they want to assess whether you're a planning person or a spontaneous person who likes doing random things instead. Being a planner is even more helpful for a leadership position because a leader must plan everything to complete the work on time. This could be answered by describing how you decide your work plan and what factors play a role. It begins with setting realistic targets, giving yourself a timeline to finish that work, allotting yourself a budget, and in the end, having realistic expectations about the results. If you are leading a team, the plan could also include the responsibilities of your team members. This way, everything seems carefully thought through, and you appear a lot more professional in front of others. You can also discuss how being spontaneous and random is essential too in some situations.
