Tanzania is striving to become a middle income country by 2025. So plans are laid down and efforts put forward to industrialize the economy. In 2010 the government initiated a Five Year Development Plan 2010–2015, aiming at promoting industrialization. This work analyzed the effect this development plan had on industrial output with 45 industries observed in both 2009 and 2013. The findings show that industries were more productive in 2013 than in 2009. Output, labor and energy have all grown positively from 2009 to 2013. It is proposed that this development plan effectively improved industrial production. For fast industrial growth, more is desired from the government, for instance, improved roads, railways, airways and marine transportation.
