問 39
Incorrectア
Both a and b are KPIs where a larger value is better. KPI a is the proportion handled to completion within the SLA target time (the higher it is, the better the agreement is kept), and b is the proportion resolved with a single inquiry (the higher the first-line resolution rate, the better), so they do not meet the condition that a smaller value is better.
Incorrectイ
KPI d (waiting time) is better when smaller, so it meets the condition, but a is the proportion completed within the target time, a KPI that is better when larger. As soon as it includes a, this option is wrong.
Incorrectウ
KPI c (the escalation proportion) is better when smaller, so it meets the condition, but b is the proportion resolved with a single inquiry, a KPI that is better when larger. As soon as it includes b, this option is wrong.
- エ
正解 Among the KPIs for raising customer satisfaction, the ones where a smaller value is better are c and d. KPI c, the proportion of incidents escalated to second-line staff, represents the share that the service desk (the first point of contact) could not resolve on its own and passed up to a higher level; the smaller it is, the stronger the first-line resolution capability, which is desirable. KPI d, the time a user spends until being connected to a staff member, is waiting time; the shorter (smaller) it is, the less stress the user feels and the higher the satisfaction. Therefore エ, which lists c and d, is the correct answer.
- When evaluating service desk KPIs, distinguish between indicators that are better when larger (first-line resolution rate, SLA achievement rate) and indicators that are better when smaller (waiting time, escalation rate).
- The lower the escalation rate and the waiting time until a response, the higher the service desk's responsiveness and customer satisfaction.
