Do you wish to invest in a micro, small and medium enterprises (MSMEs) sector in Kenya? If you are not sure which business type to invest, our MCDA business selection tool can give you the answer. Simply respond to 21 the questions by selecting answers that closely match your profile. On clicking any of the model type (WSM, AHP or WPM) the top twenty business options will be displayed. To start on, go to, http://www.business-selection.com. In addition, upon clicking one of the model type, an email with a link will be send to you. The link contains challenges and advises as given by various proprietors of the MSMEs. Our tool is based on extensive research and data collected across Kenya where business types have been matched with, among other factors, personality traits, break-even, required capital, etc. Since investors have multiple criteria, we have used a technique known as multi-criteria decision analysis (MCDA) that deduce the business ranking based on investors response.
