A cabinet with many mouths creates policy gridlock
The African National Congress (ANC) government' which was crafted by the new President of the Republic, Jacob Zuma, after 2009 general elections was much bigger than the previous administrations of Presidents Nelson Mandela, Thabo Mbeki, and Kgalema Motlanthe.
President Zuma's cabinet had 34 ministers and 33 deputy ministers. Methinks Zuma felt obliged to repay comrades who supported him after President Mbeki expelled him from the position of the deputy president of the Republic due to corruption allegations. Zuma's supporters ensured that he was elected the ANC president during the 2007 national elective congress.
It was during this conference wherein a resolution was taken to disband the policy elite investigative unit which was known as Scorpions. This unit was perceived as a threat to Zuma's march to the presidency of the Republic. Subsequent to this, the Scorpions were disbanded and the National Prosecution Authority dropped the 783 counts of corruption charges against Zuma shortly before he was elected as the President of the Republic.
As you would deduce from the above paragraph, it was very clear that when Zuma took the office in the Union Buildings, he was beholden to so many comrades who saved him from unemployment and prison. It was on this premise that he rewarded these comrades with various lucrative positions in his administration, cabinet, and state owned companies. This led to Zuma's administration becoming unnecessarily big. The ministry responsible for education was divided into two ministries - Ministry of Basic Education, and Higher Education & Training. In my view, one minister for both basic and higher education would be sufficient. In other words, there would be a ministry of education with two departments that are headed by the directors-general.
In the Presidency, Zuma created two unnecessary departments of National Planning Commission, and Performance Monitoring and Evaluation. The Department of Performance Monitoring and Evaluation was headed by Minister Collins Chabane and this made him a de facto prime minister of the Republic. How can a minister review the performance of fellow ministers? Ideally, this responsibility should have been given to the deputy president. Unfortunately, the deputy president was redundant for a period of five years.
