ese were converted to the following numeric values (seconds). Time taken to complete task Numeric Value (seconds) I don't complete this task 0 Less than 1 minutes 30 1 to 2 minutes 90 3 to 5 minutes 240 5 to 10 minutes 450 More than 10 minutes 600 Table 12: Table showing conversions used in time/cost estimate calculations Time taken to complete a particular data retrieval task was originally provided as one of the choices in the table above. Using the conversions above, all the different types of data retrieval tasks have been converted into decimal hours, per activity. This gave an estimated number of hours for an activity per week. To obtain 38 OFFICIAL - SENSITIVE the estimated value for a 100% response rate for that activity and job role, the calculated number of hours was divided by the response rate and multiplied by 100. The 100% value was summed across all activity types to obtain the number of hours spent per week across all activities. A worked example follows:  Job role = Child & Family Worker  Estimated number of decimal hours for data retrieval activities per week: Recent Safety Plan Original Safety Plan Child's birth certificate Identifying risky people in a child's network Legal documents / orders Contact details of a birth parent Educational achievements / certificates Health record / vaccinations Identifying people in a child's network that can increase safety Cultural genogram / family tree Education Health Care Plan (EHCP 1.73 2.19 0.75 1.78 1.31 1.18 0.95 0.83 2.04 0.96 1.50  Estimated value for 100% response rate for data retrieval activities per week, the response rate for Child & Family Worker was 16.18%: Recent Safety Plan Original Safety Plan Child's birth certificate Identifying risky people in a child's network Legal documents / orders Cont
