KPI019 | Navigational deficiencies V4.0
Key Performance Indicator
This KPI expresses the company’s ability to avoid navigational related deficiencies.
| Interpretation | The KPI counts the number of navigational related deficiencies including any sub-standard act, practice or condition (such as a mal functioning radar), recorded during external inspections and audits. The number of deficiencies is then made relative to the total number of external inspections. |
| Notes | This KPI is part of a range of KPIs related to deficiencies that are identified during external inspections. The deficiencies are categorized depending on their nature. The total number of recorded external inspection is used as a denominator in all these KPIs (related to deficiencies) to enable benchmarking between ships that are subject to an uneven number of external inspection. |
| Unit | Deficiencies/Inspection |
| Scope | Ship level |
| Calculation period | Quarterly |
Formula
[formula]KPI019 = \frac{PI038}{PI052}[/formula]
| PI038 | Number of navigational related deficiencies |
| PI052 | Number of recorded external inspections |
Ranking calculation example
Step 1: Calculate KPI value
| PI038 | Number of navigational related deficiencies | = 4 | |
| PI052 | Number of recorded external inspections | = 2 | |
| [formula] KPI019_{Value} [/formula] | [formula] = \frac{PI038}{PI052} [/formula] | [formula] = \frac{4}{2} [/formula] | [formula] = 2 [/formula] |
Step 2: Calculate percentile rank by comparing KPI value against other ships with the same criteria. We assume that another 99 (100 in total) participate in the ranking with the same criteria and our ship has position 10 and you are the only ship in that rank.
Step 3: Calculate the percentile rank by capturing the count of all participant below your rank (cl). The frequency of ships in your same rank (fi). The total number of ships in the ranking segment (N).
[formula] KPI019_{Percentile Ranking} = \frac{cl+05*fi}{N} * 100 = \frac{90+0.5*1}{100} * 100 = 90.50 [/formula]
Interpretation: Based on the above example, we could say that, when it comes to KPI019 Navigational deficiencies, this ship belongs in the 90.50th percentile of the ships that are being compared with based on its ranking criteria in the respective quarter.
