After survey design, questionnaire distribution, data collection and analysis, an overall summary had been consolidated below.
The details of Survey Design was located at http://qualityalchemist.blogspot.com/2012/01/hksar-ce-candidates-capability-survey.html
The questionnaires weredistributed via email to 1053 professionals. The response rate was about 7% (73 valid reply). The survey period was from 1 to 14 Jan 2012 and three reminder emails were followed.
The participants' background information were shown as follows.
Participants at the Top and Senor Management Level was about 71%.
Participants having more than 10 years working experience was about 82%.
Participants serviced in sectors of Service, Manufacturing and Government/Non-profit/Univerity was about 95%.
The codes used in this analysis were given again.
HKSAR Chief Executive Candidates 2012 on 1st Jan 2012 were:
- Mr. Henry TANG Ying-yen (唐英年) (HT)
- Mr. LEUNG Chun-ying (梁振英) (CY)
- Mr. Albert HO Chun-yan (何俊仁) (AH)
- Mr. Frederick FUNG Kin-kee (馮檢基) (FF)
Eight questions designed in the survey by adopting the Eight Quality Principles (code) were shown below:
一、市民為重 (Customer Focus) (CF)
二、領導才能 (Leadership) (LD)
三、全民參與 (Involvement of People) (IP)
四、流程方法 (Process Approach ) (PA)
五、系統管理 (System Approach to Management) (SM)
六、持續改善 (Continual Improvement) (CI)
七、據實決策 (Factual Approach to Decision Making) (FD)
八、互利關係 (Mutually Beneficial Supplier Relationships ) (MS)
The HKSAR Chief Executive (CE) Candidates' capability in each Quality Management Principle was summarized as follows.
市民為重 (Customer Focus): CY » HT ~ AH ~ FF
領導才能 (Leadership): CY » HT » AH > FF
全民參與 (Involvement of People): CY » HT ~ AH ~ FF
流程方法 (Process Approach ): CY » HT / AH / FF; HT > FF
系統管理 (System Approach to Management): CY ~> HT » AH ~ FF
持續改善 (Continual Improvement): CY » HT ~> AH ~ FF
據實決策 (Factual Approach to Decision Making): CY » HT ~ AH ~ FF
互利關係 (Mutually Beneficial Supplier Relationships ): CY ~ HT » AH ~ FF
Legend used in hypothesis test presentation:
"»" : statistically significant that p ~ 0.000
">" : statistically significant that p is below 0.05
"~>" : not statistically significant but p is around 0.1
"~" : not statistically significant
The details of Data Analysis was given at http://qualityalchemist.blogspot.com/2012/01/hksar-ce-candidates-capability-data.html
The mean of means in the 8 Quality Management Principles was summarized in the following table.
Seven-point likert scale used as follows:
(Capability Level: 7－Very Capable，６－Comparative Capable，５－ Slightly Capable，４－Accepted Capable，３－Slightly Incapable，２－Comparative Incapable，１－Very Incapable)
Graphical analysis for each HKSAR CE candidates was shown below.
By overlapping each candidate's capability chart, it found that CY's capability in all concerned aspects was close to score 5 indicating quality professionals believed that CY had "slightly capable" for the position of CE based on the Eight Quality Management Principles. However, HT's capability was found just acceptable. On the other hand, two democratic parties candidates' overall capability were below the acceptable level.
In addtition, data analysis for the mean of means was performed. Firstly, each candidate's data set was undergone Normality Test and all passed.
Then, ANOVA test was performed. The difference of candidates' overall capability was found statistically significant at 95% confident level.
Thus, the paired t-test was used to analyse the differences between two candidates. This procedure tested the null hypothesis that the true mean difference within pairs (md = m1 - m2) is equal to a hypothesized value (H0: md = m1 - m2 = m0). The alternative hypothesis can be left-tailed (md < m0), right-tailed (md > m0), or two-tailed (md ≠ m0).
The summary table was show below.
Ranking of the capability in "Overall Capabillity" of HKSAR CE candidates with statistically significant at 95% confident level was shown below.
CY » HT / AH / FF
HT > AH / FF
AH » FF
It concluded that CY had much higher overall capability score than the other candidates with statistically significant at 95% confident level. HT had higher score than the other two democratic parties candidates (AH and FF); moreover, AH had higher overall capability score than FF with statistically significant at 95% confident level.
(P.S. Recently, I found some young people "Born After 80" created a song for CY in Youtube voluntarily.)
