Enforcement ARTICLE 13 (1) Provisions of this Communiqué are enforced by the President of Information and Communication Technologies Authority. ANNEX-1 Clarifications Regarding the Measurement Method of the Response Time for Customer Services This annex contains clarifications regarding measurement of response time for customer services which are defined in this Communiqué. While performing the mentioned measurement: a: Total incoming calls to the customer services unit. b: Total calls answered by the natural person within the threshold period ascertained. c: Total calls missed within the threshold period. Shall be determined and the measurement value (d) shall be obtained by means of the following formula: d%=(b/(a-c))x100 Example: Calculation of the percentage of calls answered within 20 seconds. Incoming calls to the customer services unit within a specific measuring period are given in Table 1.

Table 1: Distribution of incoming calls to the customer services unit Distribution of Calls Number of incoming calls (a) 1.150.000 Number of calls answered 900.000 Number of calls answered within threshold period (20 sec) (b) 850.000 Number of calls answered within a period exceeding threshold period (20 sec) 50.000 Number of missed calls 250.000 Number of calls missed within threshold period (20 sec) (c) 150.000 Number of calls missed within a period exceeding threshold period (20 sec) 100.000 Percentage of calls answered within 20 seconds = (850.000/(1.150.000-150.000))x100 = 85% The value 85% obtained is the value intended to be found by estimation. ANNEX-2 Clarification Regarding the Measurement Containing the Phrase % within the shortest time This annex is issued to clarify the phrase % concluded within the shortest time which is mentioned in the measurement of resolution time for customer complaints which is defined in the Communiqué. With the measurements containing the mentioned expression, from the small to large a list is created on an basis, inclusive of values measured as well as events observed in the relevant criteria. The intended percentage of the number of observations shall be determined, which is also referred to as d%. Fractional figures in the obtained result are rounded up to the upper digit.

The measurement value in the list, which is related to the observation in the line of the figure obtained, is the figure intended to be estimated. Example: Estimation of the resolution time of complaints within the 80% -part concluded within the fastest time Complaints within a specific measuring period and resolution time are given in Table 1.
