  • My work experience has enabled me to practice in all the areas that I have been trained on in the past 17 years. The leadership experience that I have obtained through the exposure provided by Statistics South Africa during the major projects such as Labour Force Survey Reengineering (LFSR) of 2008 and Census 2011 has empowered me to lead processes from beginning to the end. Leading implementation of FinScope in SADC countries and Asia was also one of my major learning area and achievement. The summary of specific experience that I bring into this position includes the following.

The success of the programmes confirm my capability to use my expertise in different environments. In most, if not all of the projects I was never deterred by language barrier to see the projects to completion.
  • Working with other Statistical Offices abroad on the area of survey methodology provided me with the opportunity to learn different approaches that were followed based on the uniqueness of each country. I took part in a survey project in Canada which is among the developed countries, Southern Africa countries and Asia countries where economies were equally advanced.
  • Currently in Statistics South Africa, I manage contracts and statistical applications from Norway and Australia. I negotiate the payments, ensure that these applications run smoothly and engage the international service providers where necessary.
