One of todays many buzzwords is'virtual enterprise'. The objectives of the ESPRIT project VEGA are the development of an IT platform enabling such enterprises. Virtual enterprise means a number of people or smaller companies grouped together for a distinct contract, which none of them alone could or would able to get and to undertake. Modern decentralized, distributed IT solutions typically could support such virtual enterprises in their competition against those who are big or strong enough to to carry out such contracts with their internal resources alone. VEGA gathers together the necessary components as technically available and extends their capabilities as needed for a platform enabling collaboration in an flexible and distributed environment.
