16、gement X is the number of tests where the information is available; z1- / 2is the standard normal distribution function with value 1-/2. Pis an auxiliary variable calculated as: CEN/TS 15511:200820 22/122/12/+=znzXP (4) EXAMPLE Suppose that the sample size for a level 1 quality indicator is 500 (= n

17、) and the number of tests where relevant information was available is 450 (= X). Then the measured availability is X / n = 90 %. For a 95 % confidence interval there is z1- / 2= 1,96. Then we get: The auxiliary variable P= (450+1,962/2) / (500+1,962) = 89,70%, The lower confidence bound = 0,896951,9

18、6 x 0,89695 x (10,89695) / (500 + 1,962) = 87,04%, and The upper confidence bound = 0,89695+1,96 x 0,89695 x (10,89695) / (500 + 1,962) = 92,35%. This means that the true but unknown level of availability is covered by the 95 % confidence interval 87,04 % ; 92,35 % and the measured level of availabi

19、lity of 90 % has a precision of 2,96 % and +2,35 %, which holds the accuracy level. 5.6 Weighting of the results 5.6.1 Weighting according to the sample design For the discriminant types of access-point the sample design shall be based on a fully proportional model. The geographic stratification may

20、 be based on a disproportional model. In a disproportional model, an aggregated result can only be achieved as a sum of weighted strata results. If the sample design is based on a disproportional geographical model, weighting of the geographical strata shall be implemented in the calculation to rest

21、ore proportionality. The strata weights shall be determined based on census data. 5.6.2 Weighting due to failed measurement or invalid answers The correct proportions of mystery shopper visits for the geographical/population strata or for the discriminant types of access point may not be achieved, d

22、ue to cases of failed measurements (e.g. closed post offices etc.) or invalid answers. Corrective weighting shall be implemented to restore the proportionality of the access point visits according to the following procedure: All strata shall be weighted in reference to census data (population) and p

23、ostal data (discriminant types of access points), Proportions of valid answers shall not differ relatively by more or less than 20 % of the target proportions for each type of access point on an annual basis. EXAMPLE (type: Post Office): A requirement that 30 % of test items shall be posted in a Pos

24、t Office shall fulfil 30 % * 20 % = 6 % on an annual basis. CEN/TS 15511:200821 5.6.3 Changes of access point characteristics and population density The sample design in reference to geographical model and discriminant types of access point shall be reviewed at least every third year based on up-to-

25、date information. Information from the most recent 12 months period available shall be used at the time when: Sample design for the next measurement period is defined; Weights for the annual report are calculated. NOTE Census or postal data may be updated between designing of the sample and reportin

26、g. If data is available from the measurement period itself, this data shall be used for calculating the annual report. The sample design update shall be implemented by resetting the number of necessary access point visits or calls in each stratum. 5.6.4 Aggregation of results For the aggregation of

27、results, each answer is assigned its individual corrective weight. The weight depends on the target proportion of the stratum the access point visit belongs to. EXAMPLE 1 The corrective weight for the geographical area is 200 % and for discriminant type of access point 110 %. The sample size is 100.

28、 Then the individual corrective weight could be calculated as: 2 * 1,1 / 100 = 0,022 . The final weights for each valid answer shall not vary more than between 25 % and 400 % around the value of 1/sample size. EXAMPLE 2 With a sample size of 100 valid answers each weight shall be within the interval

29、 0,0025 ; 0,04 . 6. Mystery Shopper Approach 6.1 General To conduct an availability of information measurement it is recommended to use the Mystery Shopper Approach. The mystery shopper takes the role of the customer and registers the level of service that is offered. The mystery shopper shall be we

30、ll prepared for the task. Every move of the mystery shopper shall be pre-planned carefully, which includes the method in which the information of interest is gathered and recorded. The appearance of the mystery shopper shall be that of a regular customer. It is of great importance that no hints on t

31、he real purpose of the visit are given. This secures that the mystery shopper is served the same way, as a regular customer would be in this situation. The mystery shopper shall be provided with a different set of questions in each consecutive measurement period, which is relevant for the access poi

32、nt visited, or shall be deployed to another access point, so that the risk of identifying him is kept at minimum. It is recommended to adapt the form and content of questioning to the local circumstances of the access point, as far as the aim of the measurement allows it. The mystery shopper shall f

33、irst of all record (or “measure”) physical facts connected to technical or human aspects of the service (factual information). All questions regarding factual information shall be asked in closed form. CEN/TS 15511:200822 Moreover, the mystery shopper should, while conducting the measurement, additi

34、onally record the impression he gets on subjective factors like for example friendliness or helpfulness of the staff, that can be used as indicators in fields of study relating to, for example, customer satisfaction, which forms no part of this Technical Specification. Furthermore the may collect in

35、formation on subjects not directly related to this Technical Specification as, for example, how well marketing strategies of the operators are carried out at the access points. This mystery shopper measurement as proposed in this Technical Specification may be added to an existing mystery shopper me

36、asurement. Also, new fields of study may be included to the Mystery Shopper Quality of Service at the request of the operator. The course of each Mystery Shopper Visit shall be sufficiently detailed in a questionnaire. The course of the visit shall be planned in a way that keeps the mystery shopper

37、inconspicuous to the staff. The mystery shopper shall record at each visit, if special arrangements are in place at the access point to facilitate equal access for all postal customers (see Annex C for a list of special arrangements to make the information available). Resulting from this the questio

38、nnaire should contain tasks that can be done generally, for example a check for the opening hours, as well as tasks that can only be done one at a time, for example the gathering of information on different universal services. 6.2 Type of Information Channel 6.2.1 Visit at the Access Point 6.2.1.1 G

39、eneral The mystery shopper shall be deployed to one or more of the following types of access-points to collect the necessary information: Pillar box, Post office or Shop with a full range of universal postal service, Mobile Postal Outlet with predictable opening hours at fixed stationary points, Pic

40、k-up point for collecting parcels, registered or insured letters, all of which are local logistic units that require a more or less elaborate network of mystery shoppers to cover a whole country (see chapter 4.3). Concerning the collection of data about the availability of information, the main sour

41、ces for the mystery shoppers are: Information put on an official sign or table displayed at the premises, Information printed on brochures or leaflets, Information given personally by the staff of the premises themselves. 6.2.1.2 Pillar Box If official information is publicly available or provided b

42、y the postal operator on the location of pillar-boxes, mystery shoppers shall visit these according to the sample plan. The Information about collection days and collection times shall be checked. If information is available about the actual next collection time this shall be recorded as well. CEN/T

43、S 15511:200823 The mystery shopper should also register, if other additional information is given, for example: Nearest other pillar box, preferably with extended service (later collection time), Nearest postal access point providing a full range of universal postal services, If it is not for genera

44、l service (for example a meter-box), If the post-box offers special services (like night clearances for regional addressees). 6.2.1.3 Access Points providing a full range of universal Postal Services If official information is publicly available or provided by the postal operator on the location of

45、post offices or other access points providing a full range of universal postal services, mystery shoppers shall visit these according to the sample plan. The first thing the mystery shopper must check is whether the postal access point exists at the given address and if a postal service counter can

46、be found there easily. If he stands outside the postal access point he shall check if the opening hours can be found on the outside or on a special sign in case of a mobile postal outlet12. On entering the postal access point the mystery shopper shall behave like a regular customer. In the questionn

47、aire the mystery shopper shall be provided with a distinct, preset question about the one aspect of postal information he has to test, for example to which to complain to since his parcel is damaged. The measurement system shall be set up in a way that throughout the country all relevant service inf

48、ormation is tested at a random but representative pattern that secures that all sorts of information get their share within the design (see clause 5). The mystery shopper shall try to find written information on the relevant aspects of the test first, preferably in the form of something that he can

49、take with him for further examination (brochures or leaflets). If no written information is available or if the nature of the information is so that it can only be obtained by conversation, he shall ask the staff. He is allowed to make notes on a neutral block or paper. If a special information-counter is available he shall choose this one, otherwise he shall go to the regular counters. For the choice of counters, a sampling method shall be applied that reduces the element of choice for the myst
