How are you concluding that " protect against false information based on insufficient data" this is false information or the data is insufficient? BA can propose changes. So based on the elimination I am rounding to Option C

Because he has only two days of observation for his data. My logic is BA needs more days data to come to a conclusion of the under utilization.

Selected Answer: B

The information gathered over just two days (Monday and Wednesday) may not provide a complete or accurate picture of the booking clerk’s performance or workload. There could be various factors influencing the observed idle time, such as lower customer demand on those particular days, holidays, or specific operational issues that may not be representative of the usual workload. To ensure that the BA’s conclusions are based on reliable and comprehensive data, it’s essential to conduct further analysis. This might involve: • Observing the clerk’s activities over a longer period (e.g., a full week or across different times of day). • Analyzing peak and off-peak hours to understand variations in customer demand. • Gathering data on other factors that could impact the clerk’s performance (e.g., system issues, customer behavior patterns, or business hours). This approach helps to protect against false conclusions that might be drawn from a limited or non-representative sample of data.

I would go with D: page 307, the step after conducting observation is to confirm and present observation results.

Selected Answer: B

B - there's insufficient information in only 2 days of the week. Weekends could be busier for example.
