Frequently Asked Questions
What IT services can be outsourced?
Virtually any IT function can be outsourced including software development, cloud management, cybersecurity, technical support, QA testing, database administration, network management, and emerging technologies like AI/ML and blockchain. Organizations typically start with non-core functions before expanding to strategic areas.
How much can companies save through IT outsourcing?
Cost savings typically range 30-60% depending on services, geographic location, and engagement model. However, modern IT outsourcing focuses beyond cost savings to expertise access, faster time-to-market, innovation, and scalability that in-house teams struggle to match.
What are the risks of IT outsourcing?
Primary risks include communication challenges, quality concerns, security vulnerabilities, and vendor dependency. Mitigate through thorough vendor selection, clear contracts, robust governance, security protocols, and maintaining some internal capabilities for oversight and strategic direction.
Should we outsource offshore, nearshore, or onshore?
Choice depends on priorities: offshore (Philippines, India) offers maximum cost savings; nearshore (Latin America for US, Eastern Europe for EU) balances costs with timezone/cultural proximity; onshore provides easiest collaboration at higher costs. Many companies use multi-sourcing strategies combining models.
How do we manage outsourced IT teams effectively?
Success requires clear requirements, defined processes, regular communication, appropriate tools (project management, collaboration platforms), performance metrics, and treating outsourced teams as partners rather than vendors. Invest in relationship building and knowledge transfer.
