AIOps and analytics foster a culture of continuous improvement by providing organizations with actionable intelligence to optimize workflows, enhance service quality, and align IT operations with business goals.
Despite an era of rapid digital transformation, many enterprises, even those that consider themselves lean, find that 70% to 80% of their IT budgets are absorbed by routine “run-the-business” operations. This leaves little financial room for innovation, process improvement, or strategic transformation.
At the same time, application sprawl has become a silent disruptor; driven by years of unchecked software purchases across departments, resulting in a bloated, complex, and often redundant application landscape. According to Gartner, enterprise software spending is expected to reach $891 billion by 2025. Yet a significant portion of that spend is wasted on underutilized or redundant applications.
This is where application rationalization becomes not just a cost-saving tactic but a strategic imperative. By taking a structured approach to assess, consolidate, retire, or modernizing application portfolios, organizations not only reduce unnecessary IT spend, but also simplify IT, boost agility, and reallocate resources toward customer-facing innovation and future-ready technologies.
A recent survey found that 48% of M&A professionals are now using AI in their due diligence processes, a substantial increase from just 20% in 2018, highlighting the growing recognition of AI’s potential to transform M&A practices.
A Brief Overview of Application Rationalization?
Application rationalization is the strategic process of reviewing and evaluating your organization’s software portfolio to determine which applications should be retained, upgraded, retired, or consolidated. The goal is to assess each application’s total cost, business value, usage, and risk, to ensure your IT environment is fully aligned with business objectives.
This approach combines analytics, governance, and intelligent automation to streamline the portfolio. The result is a more agile, cost-effective, and scalable IT environment that supports faster decision-making, smoother operations, and future-ready innovation.
Think of your application portfolio like a child’s toy room. Just as kids sort through their toys – keeping the favorites, donating the ones they’ve outgrown, and clearing space for new ones—application rationalization helps organizations do the same with their software tools. Keep what delivers value. Retire what doesn’t. And make room for better investments.
IT Cost-Saving Opportunities Through Application Rationalization
Application rationalization is a foundational IT cost optimization strategy that enables organizations to unlock substantial savings across multiple areas. It serves as a springboard for broader cost-reduction initiatives such as:
- Optimizing software licenses and SaaS subscriptions
- Retiring underused or obsolete applications
- Streamlining server usage and data storage
- Rationalizing IT project investments
- Eliminating redundant tools and functions
- Standardizing on core technology platforms
At its core, application rationalization focuses on evaluating and selecting applications based on their proven business value. It involves carefully balancing cost against contribution, continuously tracking application performance and usage in real time, and making informed decisions to adjust the portfolio as business needs evolve.
Top 7 Strategic Benefits of Application Rationalization for Modern Enterprises
Application Rationalization benefits when executed strategically, it delivers measurable outcomes across financial, operational, and innovation dimensions. Here’s a breakdown of the seven most powerful benefits, backed by industry data and examples.
1. Free Up Resources to Fuel Innovation
One of the most immediate and strategic gains from rationalizing applications is the reallocation of valuable resources. Instead of dedicating time and money to maintaining outdated or redundant applications, organizations can redirect those resources toward innovation-driven initiatives. According to Oracle, modern digital leaders called “digital vanguards” allocate nearly 26% of their tech budgets to innovation, compared to only 18% at less advanced firms. Yet many organizations still spend 70–80% of their IT budget maintaining legacy systems and redundant applications – resources better spent elsewhere. By pruning redundant applications, companies can reclaim up to 20% of application spending within a year, channeling the savings into transformative initiatives like AI pilots or R&D.
2. Lower Infrastructure and Operational Costs
Each application incurs a stack of hidden costs – from server provisioning and data backups to licensing and compliance monitoring. A rationalized IT landscape drastically cuts down on these complexities. According to a report, 54% of IT leaders acknowledge wasting 10–20% of their IT budget on inefficiencies, especially poor application management. By consolidating systems, businesses not only reduce support overhead but also simplify hardware provisioning and data storage
3. Maximize Development Team Capacity
Legacy systems and fragmented platforms weigh down development teams. App Rationalization reduces this burden, freeing developers to focus on delivering innovation rather than maintaining outdated software. With fewer systems to integrate, teams can streamline CI/CD pipelines, simplify testing processes, and accelerate delivery. TechRepublic notes that development velocity can jump up to 50% in optimized environments. In one case, a banking client halved its release cycle after consolidating middleware and reducing redundant services, demonstrating how rationalization directly impacts delivery speed and innovation.
4. Prevent Application Sprawl and Shadow IT
Without proper governance, enterprises often accumulate overlapping tools that serve similar functions. Studies show that the average enterprise uses over 1,000 applications, with 25–30% offering redundant capabilities. This sprawl not only inflates costs but also increases security and compliance risks. Rationalization introduces structure through policies, approval workflows, and regular portfolio reviews. It helps prevent shadow IT and ensures that applications are business-critical and value-aligned. By continuously reviewing usage and eliminating redundancy, organizations maintain a lean, secure, and manageable IT environment.
5. Show Tangible Financial Impact
By adopting rationalization as a repeatable, data-driven discipline, businesses can transparently track usage, costs, and application value. An industry report shows that pre-deal rationalization efforts help reduce the number of applications by 30%, slashing operating costs by 35% – directly improving deal valuations. This transparency builds a strong business case for IT transformation and provides the evidence needed to secure further investments.
6. Strengthen Security and Risk Posture
Each redundant or outdated application represents a potential security loophole. A fragmented landscape complicates patching, monitoring, and regulatory compliance. By rationalizing applications, organizations eliminate these soft spots and reduce their overall attack surface. Fewer applications mean fewer vulnerabilities, better identity and access management, and a more streamlined path to achieving security certifications or industry compliance. Rationalization also simplifies data governance and boosts the overall health of the enterprise’s digital infrastructure.
7. Align IT Spending with Business Objectives
By streamlining their application ecosystem, organizations gain deeper insight into how each system contributes to business performance. This visibility allows IT and business leaders to better align technology investments with strategic goals. Rationalization ensures that future IT budgets are allocated to applications that support core business functions, drive agility, and enable digital growth.
Seven Steps to Application Rationalization
To reduce cost, complexity and redundancy across enterprise applications, Gartner outlines a structured seven-step approach to application portfolio rationalization. This process helps organizations align IT investments with business value, eliminate duplication and improve operational efficiency.
Step 1: Prepare
Begin by forming a cross-functional team involving business and IT stakeholders. Educate them on the importance of business sponsorship, and define the program’s scope, success criteria and inventory methodology. Use Gartner’s TIME model (Tolerate, Invest, Migrate, Eliminate) and pace-layered application strategy to assess and prioritize applications effectively.
Step 2: Create an Application Inventory
Build a detailed inventory of all applications, categorized by business unit and capability. Include both business and nonbusiness applications, capturing metadata such as usage, ownership and cost. This inventory forms the foundation for rationalization and should be maintained continuously.
Step 3: Assess Application Fitness
Evaluate applications based on technical, business and cost fitness. For overlapping business apps, apply the TIME framework to score fitness. For nonbusiness apps, use simpler popularity or usage metrics.
Step 4: Propose Consolidation Candidates
Identify overlaps and assess which applications can be consolidated. Choose a standardized solution, evaluate integration and data migration needs and anticipate resistance. Ensure that business processes are remapped and data retention policies are addressed.
Step 5: Approve the Rationalization Plan
Secure business sponsorship and funding by building strong business cases focused on reducing cost, complexity and risk. Prioritize projects with clear ROI and likelihood of quick wins.
Step 6: Execute Rationalization
Migrate to the chosen standardized application, train users, and decommission legacy systems. Assign an “application undertaker” to manage dependencies, data archiving and full termination of retired applications.
Step 7: Celebrate and Iterate
Acknowledge the team’s achievements and institutionalize rationalization as an ongoing practice. Share success stories, reward contributions and prepare for the next rationalization cycle.
