Development planning aims at realising a comprehensive socio-economic development.
They aim at perpetuating positive aspects and eliminating negative ones within a framework of economic balance. The five-year plans were set within this framework thereby organically linking between production and investment, on the one hand, and production and consumption on the other hand. They considered production as the aim and investment as the means to realise this aim. The plans, also emphasized on the necessity to mobilize and orchestrate all effort and material, financial and manpower resources in the country to achieve great economic accomplishments in order to build a strong national economy ever depanding on self capabilities. Thus development plans have opened up new horizons for various investments and for individual, private sector, cooperative sector and joint sector initiatives to assume their proper roles in realising the aspired-for development, so much so strategic development depends on plural economy.
