adopting impact sourcing strategies. Impact sourcing service providers Impact sourcing service providers ('ISSPs') are organizations within the tertiary/services sector with specific social objectives. Many of these firms, as an explicit part of their mission or objectives, aim to generate employment for and upgrade skills of workers from poor and vulnerable communities. Achaya notes two "promising" examples, Head Held High, based in Bengaluru (Bangalore), whose impact is focussed on young people, women and marginalised communities in rural India, and NextWealth, also based in Bengaluru, who work to sub-contract outsourcing opportunities to potential outsourcing providers. Value proposition Impact sourcing is viewed as an effective market-based solution to poverty alleviation and shows the potential to create millions of jobs for the young and those living in poverty. While long-term studies have yet to take place, impact sourcing has begun to demonstrate positive impacts on multiple aspects of well-being for workers and their families. Studies indicate that impact sourcing employees benefit with income increases of anywhere from 40 percent to 200 percent. Employment in impact sourcing also serves as an initial entry point into the formal economy, which leads to valuable job experience that can help workers pay their way through school, receive higher education and move towards better careers. Impact sourcing also has the potential to benefit traditional BPO service providers, who are actively seeking alternate lower-cost destinations (i.e. smaller cities and/or rural towns) and pools of new and more affordable qualified workers. While the potential benefits of impact sourcing are compelling, the sector faces challenges that have prevented it from reaching its full potential. These obstacles include the ability of ISSPs to secure new work and clients, as well as the ability for ISSPs to partner with and sub-contract for larger, more traditional BPO service providers. Market size Impact sourcing is considered to be in its early stage of development. In 2011 the current market size was estimated at $4.5 billion, which represented about 4% of the $119 billion BPO industry. Impact Sourcing directly employs approximately 144,000 people across all segments. Some analysts estimate that impact sourcing has the potential to grow to $20 billion by 2015, employing 780,000 socioeconomically disadvantaged people globally. Avasant estimated that the market had the ability to grow to represent 23% of the total BPO industry by 2020. References External links Accenture.
