With the recent departure of two of its employees, an IT helpdesk team is now understaffed and finding it difficult to keep up with the current workload. The number of tickets being received has increased as well as the number of days to resolve the tickets. The IT manager has set up a meeting with the IT director to request funding for two new helpdesk agents. To prepare for the meeting, the manager is interested in showing the tickets processed against ticket volume over the past year.
What type of chart should the manager use to effectively show the change in processing rate over time?
To effectively show the change in processing rate over time, a line chart is the best option. A line chart can clearly display trends over a continuous period, making it easy to visualize the widening gap between the number of tickets being processed and the number of tickets received each month over the past year. This will allow the IT manager to clearly demonstrate the increasing workload and the decreasing ability to process tickets, thereby justifying the need for additional helpdesk agents.
An analyst at a bank is trying to identify research questions for an analytical study on top customer issues across branches. During an interview with a branch manager, the analyst asks the manager what their top customer concerns are relating to this branch? After the manager's reply, the analyst asks a follow up question on how their top customer concerns compare against the top customer concerns across all branches?
Was the analyst's follow-up question valid?
The analyst's follow-up question is valid because it builds on the initial question by allowing a comparison between branch-specific concerns and overall trends across all branches. This helps the analyst identify whether the issues at the specific branch are unique or reflective of broader customer concerns within the bank. Such a comparison is crucial for understanding the context of the issues and for developing targeted strategies to address them effectively.
Interested in experimenting with analytics, a manufacturing company hires an analyst to see how the capability can be developed within its organization. The analyst is getting started and recognizes the need to show value from the onset of their work to gain upper management's trust and future funding.
What action will accomplish these objectives?
To quickly demonstrate value and gain upper management's trust and future funding, it is important to develop a meaningful question that can be answered using data the company already possesses. This approach ensures that the analyst can provide actionable insights without the need for immediate additional data collection or resources, thereby showing immediate value. Option C satisfies this requirement by utilizing existing data to address relevant questions, which is crucial for gaining initial support in a new analytics initiative.
A financial software company has growth and expansion as one of their top strategic priorities for the year. The senior executive team would like to assess their sales performance over the last 3 years to help set sales objectives. In discussion with the business analytics manager, for a comprehensive sales report, the sales lead recommends looking into the number of contracts signed over the past 3 years and the dollar value for the signed contracts.
Which other question is important to consider when evaluating sales performance?
When evaluating sales performance, it is important to consider customer retention over the past 3 years. Customer retention provides insights into customer satisfaction and loyalty, which are critical for sustained revenue and growth. If customers are retained, it indicates recurring revenue and potential upselling opportunities, which contribute positively to sales performance. Other metrics, while useful, may not directly reflect the ongoing success and stability of the company's sales efforts.
The analytics team is assessing the results of their analysis. They are surprised to find that their data indicates two events seem to be strongly related even though the general belief in the organization is that they are independent of each other. Knowing that this information will be used for decision making, they are concerned about presenting this data.
At an impasse, the business analysis professional reminds them that the data can be presented as long as the team has:
When assessing the results of data analysis, it's crucial to ensure the reliability and accuracy of the findings. The best way to minimize the risk of acting on incorrect data is to have the ability to rerun the data analysis and obtain the same results. This reproducibility confirms that the data analysis is consistent and not a result of random chance or error, thereby providing a sound basis for decision-making.
