A major challenge facing systems integrators is to serve more customers, deal with more vendors in the ecosystem, create more specializations or verticals and to do all this without a linear increase in head count. Another challenge is to identify trends in service delivery models and technology deployment and to use H/R to both meet current needs and uncertain future needs. Talent management could be done by using training centers to plug gaps in competencies, using referral networks to farm universities and competitors, use acquisitions and JVs to meet capacity requirements.
