Development refers to the improvement in country's economic and social conditions. More specifically, it is the improvements in way of managing an area's natural and human resources in order to create wealth and improve people's lives.

Economics generally agrees that economic development and growth are influenced by four factors , namely Human resources, physical capital, natural resources and technology. highly developed countries have governments that focus on these areas. 

Human resources, The skills, education and training of the labor force have direct effect on the growth of the economy. A skilled well-trained workforce is more productive and will produce a high quality output that adds efficiently to an economy, like in South Africa today the production of vaccines will save a lot of money and probably add on the economy of the country as some countries may buy from us. Physical capital, improvements and investment in physical capital such as roadways, machinery and factories will reduce the cost and increase the efficiency of economic output. Factories and equipment that are modern and well maintained are more productive than physical labor, higher productivity leads to increased output, in South Africa they have installed the tollgates in the roadways which adds on the economy of the country. Natural resources, The quantity and availability of natural resources affect the rate of economic growth. The discovery of more natural resources such as oil, or mineral deposits, will give a boost to the economy by increasing a country's production capacity, the effectiveness of a country at utilizing and exploiting its natural resources is a function of the skills of the labor force . like in South Africa we are rich in natural resources but the fact that we do not have skilled people to process them we have to sell them in lower prices and buy them processed in higher prices which affect our economy.

Technology, improvements in technology have a high impact on economic growth. as the scientific community makes more discoveries, managers find ways to apply these innovations as more sophisticated production techniques.
