Upgrading technology is not rationalisation, rather, the groundwork that happens beforehand, including leadership alignment, structured governance, and ongoing optimisation.
According to Stats SA, 60% to 80% of IT budgets are allocated to maintaining legacy systems instead of enabling growth, significantly delaying meaningful progress.
ITWeb reports that South Africa’s IT services market is expected to grow from R104.9 billion in 2024 to R182 billion by 2028, driven by cloud adoption, AI, and digital transformation, yet much of this potential is slowed by outdated infrastructure and integration challenges.
Risks in Transformation
Market trends highlight increasing pressure on organisations to innovate, while remaining constrained by the very legacy systems that power their core operations.
Immediate financial and reputational consequences often arise from disruption, unless it is carefully planned as a deliberate and strategic move. This is why At least 40%–60% of enterprises delay transformation, even when the long-term cost of inaction is substantially higher.
Adapting legacy systems to artificial intelligence, cloud-native architectures, or real-time analytics, is still a biggest challenge as they were never designed for this level of speed, scale, or flexibility. More than 50 %of South African CIOs prioritise transformation, yet execution is frequently slowed by legacy constraints, with hesitation further compounded by broader challenges. CIOs, & CTOs
must navigate budget pressures, critical skills shortages, and ongoing energy instability, all of which elevate the perceived risk of large-scale transformation initiatives.
Digital Transformation initiatives often fail when organisations underestimate the operational complexity and risk involved.
Coverage from ITWeb shows how legacy systems continue to drain up to 70% of IT budgets and slow transformation efforts, while businesses struggle to integrate modern capabilities such as AI and real-time analytics into outdated architectures. The result is a widening gap between what organisations need to compete effectively and what their technology environments are able to deliver.
The most successful strategies:
The 2024 BCX Digital Innovation Index shows that organisations adopting these princices achieve faster transformation and higher ROI, while those delaying face budget strain and operational risk
• Rationalise all business applications and processes
• Implement incremental, agility-acbased changes
• Unlock legacy systems with application programming interface (API)
• Prioritise business value over technology
Rationalisation is not about ripping out systems, it is about understanding what to keep, what to evolve, and what to replace, all while keeping the business running.
This shift mirrors broader thinking in enterprise innovation, where incremental change, experimentation, and adaptability outperform rigid, high-risk transformations.
Modernisation is about creating an architecture that enables continuous innovation, not just simply replacing technology. Organisations that get this right move faster, integrate systems more effectively, and develop new digital capabilities without destabilising their operations.
