By the mid-1980s Tanzania realized that her development policies and strategies had proved a failure as far as socio-economic development was concerned. In 1986, the until-thenresistant regime to IMF and World Bank packages aimed at providing economic reform assistance gave in and a reform package was agreed upon. The content of the package included policies that were at loggerheads with the key components of the policy of Socialism and Self Reliance as outlined in the 1967 Arusha Declaration: The fundamental policy that guided most sectoral development policies. Political and economic developments led to further sidelining of the Arusha Declaration policies when, for example, the Zanzibar Resolution of, 1991 did away with an important pillar of the Declaration -the Leadership Code. Causes of the failure of the Arusha Declaration policies to realize the intended objectives can be attributed to internal and external factors. In short we can say social- ism had failed and capitalism was winning, and winning fast! With these political and economic developments Tanzania found herself without a meta-policy to serve as the basis and guide for the development effort. Something had to be put in place for that purpose. In 1995, the government appointed a group of experts to formulate a policy document to that effect in consultation with the different sections of the Tanzanian community at large. The outcome was the Tanzania Development Vision 2025.
