Unit of Analysis
The unit of analysis is a critical factor in the study. It is typically a system of action rather an individual or group of individuals. Case studies tend to be selective, focusing on one or two issues that are fundamental to understanding the system being examined. Thus, this study shall be focusing both the individual and general level in determining the impacts of selective outsourcing of IT and services present in Standard Chartered Bank.
Respondents of the Study
The general population for this study was composed of selected personnel in the organisation numbering to 60 respondents. The interviews for managers whose function is directly related to the organisation and implementation of the selective outsourcing strategy employed by the company were also provided.
Although it is obviously desirable to obtain a larger sample size, the survey process about selective outsourcing took a full day to complete and assessors a half day to rate. Thus, this study using that sample size collated substantial information from the survey respondents. The quality of response the study expects to get will offset the number of respondents that were included. Primarily, sixty (60) is an ideal number for a sample in this kind of organisation. A minimum of 20% of the total respondents from the population would merit a reliable sample size and it should be based on Slovin’s formula.
Basically, Guilford, J.P. and B. Fruchter (1973), initiated that it is advisable to use the Slovin’s formula in choosing sample sizes. Thus, the sample size of the population in this paper was determined by Slovin’s formula. The formula of Slovin (1960) is given as follows:
n = a sample size
N= population size
e= desired margin of error (percent allowance for non-precision because of the use of the sample instead of the population).
Finally, the most pressing issue would be the quality of feedback/responses that is gathered from the respondents. This study did not assume that the self-rating and the observer’s rating on the personnel true and valid. It is important to reserve the judgment and analyses about the difference in the result of the self-raters and observers and cross tabulate it in order to lessen the issue of getting non-truthful responses. Moreover, a copy of the personnel’s productivity index such as their time cards, their positions, their output and their job descriptions in order to lessen the dependence on the survey questionnaire was obtained. The data obtained from the official documents of the company and the result of the selective outsourcing questionnaire, including the interviews, which are the basis for the analysis of the study.
Instruments to be Used
To determine the effects of selective outsourcing in the company particularly in Standard Chartered Bank, a questionnaire and a set of guide questions for the interview that is asked to the intended respondents was prepared. The respondents graded each statement in the survey-questionnaire using a Likert scale with a five-response scale wherein respondents are given five response choices. The equivalent weights for the answers are:(责任编辑：charlie)
