KPI033 | Vetting deficiencies V4.0

Key Performance Indicator

This KPI expresses the ship manager’s ability to avoid observations during commercial inspections.

Interpretation	The KPI counts the number of observations (including any substandard act, practice or condition) recorded during commercial inspections. The number of deficiencies and negative observations is then made relative to the total number of vetting inspections.
Unit	Observations/Inspections
Scope	Ship level
Calculation period	Quarterly

Formula

[formula]KPI033 = \frac{PI058}{PI059}[/formula]

PI058	Number of observations during commercial inspections
PI059	Number of commercial inspections

Ranking calculation example

Step 1: Calculate KPI value

PI058	Number of observations during commercial inspections	= 4
PI059	Number of commercial inspections	= 2
[formula] KPI033_{Value} [/formula]	[formula] = \frac{PI058}{PI059}[/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] KPI033_{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 KPI033 Vetting 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.
