Mainframe and Open IT expertise
HH&S senior consultants bring extensive experience of both IBM Mainframe environments — z/OS MVS, z/VM and Linux on IBM Z — and Open Systems, including UNIX/Linux, Windows, Java and Internet technologies.
What sets us apart is the breadth of our IT background. We began our careers on IBM Mainframe systems and followed the evolution of computing through minicomputers, distributed systems and modern platforms. This broad perspective gives us the technical depth required to design, migrate, transform and modernise IT architectures.
Our core specialism is the IBM Mainframe, particularly z/OS MVS and z/VM. We provide Mainframe expertise and guidance to organisations that no longer have these capabilities in-house.
Our strength is our ability to discuss bits and bytes with engineers and developers, SLAs with operations and application managers, TCO and ROI with IT procurement teams, and strategy with the CIO.
Our technical expertise, responsiveness and delivery record across consulting, development, migration, technical support, systems and network administration, and training have earned us a strong reputation with major IT organisations.
HH&S also provides its clients with practical research, evaluation and technical prototyping capabilities. By continually assessing and testing new solutions, we maintain a clear view of the technology landscape and help clients build robust, sustainable and cost-effective architectures while avoiding common technical pitfalls.
As an independent firm, we are responsive and flexible. We have built a reputation for fast, effective delivery among both major organisations and SMEs.
Our clients also value our ability to share knowledge. Our assignments and training help their teams gain practical answers, new ideas and clear technical recommendations.
