Terrain condition of the Municipality of G. Karaiskakis are favourable for livestock farming and, nowadays, an important part of the population is engaged in these activities. Considering the characteristics of the study area and of the Greek cheese making industry, this paper analyzes from a financial viewpoint the viability of a small-sized cheese making unit that will produce two cheese products, namely feta and graviera and two by-products, i.e. butter and mizithra cheese. The selection of the products was based on a SWOT analysis (products with high demand, offered at attractive prices) and financial requirements (mainly to keep the investment cost at affordable levels). The results of the deterministic and stochastic financial analysis show that the proposed investment will be profitable. Nevertheless, it is evident that the final outcome will depend on the organizational actions that should be made on the basis of a realistic strategic plan.
