Automation in IT operations enable agility, resilience, and operational excellence, paving the way for organizations to adapt swiftly to changing environments, deliver superior services, and achieve sustainable success in today's dynamic digital landscape.
Next-generation application management fueled by AIOps is revolutionizing how organizations monitor performance, modernize applications, and manage the entire application lifecycle.
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.
In the digital age, businesses rely on a vast array of applications to support everything from customer engagement and data analytics to supply chain management and internal collaboration. Over time, as organizations grow, merge, and adapt to new technologies, their application portfolios tend to become increasingly complex, fragmented, and difficult to manage. This is where application rationalization—the strategic process of assessing and optimizing an organization’s application landscape—emerges as a crucial enabler of transformation.
At its core, application rationalization involves identifying which applications are truly necessary, which can be consolidated, modernized, or retired, and aligning the entire ecosystem with business goals. When done effectively, this process streamlines IT operations, reduces technical debt, and liberates valuable resources. Without a rationalized application strategy, IT teams spend significant time and resources on maintaining legacy systems rather than focusing on innovation and growth.
This blog will explore the key steps, benefits, and insights into how application rationalization can act as a catalyst for IT efficiency, enabling organizations to achieve greater agility, scalability, and long-term success in their transformation efforts.
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.
Most enterprises today operate with hundreds, if not thousands, of applications. According to Salesforce survey, the average number of applications in an enterprise grew from 843 in 2021 to 1,061 in 2023, a 25% increase. Despite the large number of applications, utilization rates are often low. A study by Productiv found that, on average, only 45% of company apps are used regularly, indicating that more than half of the applications may be underutilized or redundant large. This “application sprawl” leads to a number of challenges:
These issues contribute to what many CIOs call “technical debt,” where past technology decisions hinder future progress. Without intervention, organizations risk falling further behind in their transformation efforts.
Application rationalization is the process of evaluating an organization’s software portfolio to determine which applications should be retained, retired, replaced, or consolidated. The goal is to eliminate redundancies, reduce costs, and improve operational efficiency. This process typically involves:
Application rationalization delivers value across multiple dimensions of IT and business performance:
1. Improved IT Efficiency
By eliminating duplicate and low-value applications, IT teams can focus on maintaining and innovating core systems. Less complexity means faster response times and easier troubleshooting.
2. Cost Reduction
According to Gartner, organizations can save up to 30% in application-related costs by rationalizing their portfolios. Savings come from reduced licensing, support, infrastructure, and maintenance overheads.
3. Enhanced Agility and Scalability
Streamlined application stacks allow organizations to adapt more quickly to change, scale faster, and deploy new solutions with fewer integration challenges.
4. Reduced Risk and Improved Security
Decommissioning legacy or unused applications minimizes the security attack surface and ensures compliance with evolving regulatory standards.
5. Foundation for Digital Transformation
With fewer strategic applications, organizations can more easily adopt cloud, AI, and other emerging technologies—setting the stage for innovation.
Cloud computing plays a pivotal role in modern application rationalization strategies. By migrating legacy applications to cloud-based solutions, organizations can reduce infrastructure costs, improve accessibility, and enhance scalability. Cloud-native applications offer greater agility and security, making them an attractive alternative to traditional on-premise software.
Application Portfolio Management (APM) is the discipline that provides visibility and governance over the application landscape, making it a cornerstone of successful application rationalization. APM provides a strategic framework to continuously monitor, evaluate, and optimize applications.
APM helps organizations:
With iAM, every application becomes a node within a larger, interconnected system. The “intelligent” part isn’t merely about using AI to automate processes but about leveraging data insights to understand, predict, and improve the entire ecosystem’s functionality.
Consider the practical applications:
Application rationalization is most effective when integrated with application portfolio management (APM) best practices. Organizations can successfully rationalize their applications following the steps below:
Before starting the rationalization process, define your business goals. Are you aiming to reduce costs, enhance security, or modernize IT infrastructure? Align application rationalization efforts with these objectives to ensure meaningful outcomes.
A thorough assessment of the current application portfolio is essential. Gather data on application usage, costs, dependencies, and business value. Categorize applications based on their functionality and impact on operations.
Identify redundant or underutilized applications. If multiple tools perform similar functions, consolidate them to reduce complexity. Leverage analytics and stakeholder feedback to assess actual usage patterns.
A popular model for application rationalization is the TIME framework, which categorizes applications into four groups:
Security should be a top priority during rationalization. Assess applications for vulnerabilities, outdated technology, and compliance risks. Replace legacy systems that no longer meet regulatory standards.
Application rationalization is not a one-time process. Organizations should leverage AI-driven tools and automation to continuously monitor application performance, flag inefficiencies, and optimize resources dynamically.
While application rationalization offers significant benefits—like cost savings, improved IT efficiency, and streamlined operations—it also comes with its own set of challenges that organizations must navigate carefully. Here’s a breakdown of the key challenges of application rationalization:
One of the biggest hurdles for an organization is knowing what you have. As a result, they lack a comprehensive and up-to-date inventory of all their applications, especially when dealing with:
Without full visibility, rationalization efforts are incomplete or misaligned.
Deciding which applications to keep, modernize, or retire can be highly subjective if not based on reliable data. Challenges include:
This can lead to political decisions or resistance from stakeholders who are emotionally or operationally attached to certain apps.
Application rationalization often involves retiring tools that teams rely on, which can trigger pushback from business units. Common issues include:
Without strong change management and communication, adoption of rationalization initiatives can stall.
Applications are rarely isolated—they often connect with databases, APIs, and other tools. Retiring or replacing one app without understanding its dependencies can cause:
Mapping and analyzing dependencies is complex but critical to a smooth transition.
While rationalization aims to cut costs, short-term investments (in integration, migration, retraining, etc.) can be significant and often underestimated. Challenges include:
Cost-benefit analysis must be carefully done with both short-term disruption and long-term value in mind.
Many organizations treat rationalization as a one-off project, instead of a continuous discipline. This leads to:
A continuous application portfolio management (APM) strategy is essential to sustain the benefits.
Legacy and redundant apps may store sensitive data, and decommissioning them without proper procedures can create:
Secure data migration and disposal must be part of the rationalization plan.
Organizations lacking modern Application Portfolio Management (APM) or intelligent application management tools struggle with:

Moreover, as cloud adoption, DevOps, and composable enterprise models become the norm, application rationalization will be essential—not optional—for maintaining alignment between technology and business value. Organizations that embed rationalization into their IT governance models and transformation roadmaps will be better positioned to scale, adapt, and lead in an increasingly complex digital world.
In short, application rationalization is no longer just about reducing the noise—it’s about amplifying what matters. The businesses that embrace it as a continuous journey, rather than a one-time clean up, will build a foundation for innovation, efficiency, and sustainable success.
Application rationalization is the process of identifying, evaluating, and optimizing an organization’s software applications to eliminate redundancy, reduce costs, and improve efficiency. It involves categorizing applications for retention, retirement, replacement, or modernization based on usage, business value, and technical health.
It’s important because many organizations accumulate a bloated, fragmented application landscape over time. Rationalization helps streamline IT operations, reduce technical debt, and align technology with business goals—laying the groundwork for digital transformation and scalability.
Application rationalization delivers a wide range of benefits, including:
Cost Savings: Reduced licensing, support, and infrastructure costs by eliminating underused or redundant applications.
Improved IT Efficiency: Less time and resources spent maintaining unnecessary apps.
Increased Agility: A leaner application stack allows faster innovation and adaptability.
Better Security & Compliance: Fewer legacy systems reduce the risk of vulnerabilities and compliance issues.
Stronger Business Alignment: Ensures applications directly support current strategic and operational goals.
The application rationalization process typically involves:
Inventory – Identify all applications in the IT ecosystem.
Assessment – Analyze usage, cost, business value, and technical health.
Categorization – Classify apps using models like TIME (Tolerate, Invest, Migrate, Eliminate).
Prioritization – Focus on high-impact rationalization opportunities.
Execution – Decommission, consolidate, or modernize applications as needed.
Optimization – Monitor continuously to maintain portfolio health and avoid future sprawl.
Common challenges include:
Incomplete application inventory due to shadow IT or poor documentation.
Lack of standardized evaluation criteria, leading to subjective decision-making.
Stakeholder resistance, especially when retiring familiar tools.
Complex interdependencies between applications that complicate decommissioning.
Hidden costs in migration, integration, or retraining.
One-time mindset instead of treating rationalization as an ongoing process.
Application Portfolio Management (APM) provides the governance, tools, and visibility needed to manage the application landscape over time. Rationalization is a core function within APM—it uses APM insights to assess value, track performance, and guide decisions about which applications to keep, enhance, or retire.
APM ensures rationalization isn’t a one-off project but part of continuous IT optimization and strategic alignment.
While a comprehensive rationalization effort is often done every 1–3 years, a more agile, ongoing approach is ideal. With modern APM tools and intelligent platforms, businesses can monitor application performance, value in real-time, and continuously optimize their portfolio as business needs evolve.
Regular reviews should be part of:
1. Annual IT strategy planning
2. Post-merger integrations
3. Cloud migration initiatives
4. Cost optimization programs
Some frequent mistakes to avoid in application portfolio management includes:
1. Lack of a complete application inventory
2. Failure to involve business stakeholders in evaluating value and usage
3. Overlooking application dependencies, leading to operational disruption
4. Relying on manual processes instead of using APM tools and automation
5. Treating rationalization as a one-time effort rather than an ongoing discipline
6. Focusing only on cost, ignoring business value or user experience
