Small scale industries are defined as those with investment in plant and machinery up to Rs. 1 crore. They are characterized by small capital investment, local employment, and sole proprietorship. SSIs are important as they are labor intensive, ensure equal distribution of wealth and income, act as a link to large industries, and have export potential. Running an SSI has advantages like not requiring high technology, ability to use local resources, short gestation period, and generating local employment. A feasibility study assesses the viability of a business project by analyzing various factors such as market, resources, costs and benefits. Proper documentation and registration of a business is important for reducing liability, defining roles and objectives, and protecting intellectual property.
