Industrializing Zero Application
Maintenance
By applying a rigorous and automated approach to supporting applications,
IT organizations can reduce spending, increase repair accuracy, minimize
application debt across the portfolio, free up resources for more strategic
business imperatives and improve application yield to deliver enhanced
business outcomes.
Executive Summary
CIOs continuously struggle to balance two needs. The
first is assuring applications perform with maximum
speed and reliability at the lowest cost (i.e., are fit for use).
The second is to ensure these applications meet the
most pressing needs of the business and stay relevant
(i.e., are fit for purpose). They walk this tightrope amid
prohibitively high application maintenance costs, rapid
technological changes, and an unforgiving and highly
competitive global economy.
Ideally, CIOs can meet both these demands if
applications run on “auto pilot” and deliver intended
business outcomes without manual intervention and
related maintenance costs. We call this state of maturity
zero maintenance. While it may be very difficult to
achieve, implementing a zero-maintenance strategy
helps organizations drive quantum reductions in cost
and increased business value.
Cognizant 20-20 Insights
November 2019
Zero maintenance strategies typically focus on:
❙❙ Reducing technical debts, which frees cash and
allows organizations to bootstrap investments
on strategic initiatives.
❙❙ Improving the technical value of the portfolio
by modernizing the application, thus making it
digital-ready.
❙❙ Addressing critical bottlenecks in the
applications that support business processes by
improving application throughput, which in turn
enhances business performance.
Zero maintenance delivers the greatest benefits
when it is industrialized. This means establishing
a structured, ongoing process to identify and
categorize technological debt that applications
incur over time and minimizing them by quickly
fixing defects, improving technical infrastructure
and automating as much of the required
remediation as possible. Such an industrialized
process should also identify and optimize the
workflows that are most critical to the business to
deliver improved outcomes.
This white paper describes the importance
of industrialized zero maintenance, its key
components and best practices for achieving it.
Businesses that bring rigor to zero maintenance
can apply cost savings to fund more strategic
initiatives while improving customer satisfaction
and employee productivity.

The perpetual IT operations challenge
From the day they are put into production,
applications begin incurring four kinds of debt:
❙❙ Technical debt, caused by substandard code
and aging platforms, leading to outages,
slowdowns and other service issues.
❙❙ Functional debt, caused by a failure to update
software to meet new business requirements,
leading to change requests.
❙❙ Operational debt, caused by inefficient
operations management and a lack of
administrative tools, leading to excess manual
effort, configuration errors and increased cost.
❙❙ Knowledge debt, caused by insufficient
documentation or a lack of user training, which
increases support calls, tickets and costs.
Through proven, documented and reliable
processes, an industrialized zero maintenance
strategy can minimize both kinds of effort:
❙❙ Nondiscretionary effort required to keep
applications and the business running.
❙❙ Discretionaryeffortrequiredtoupdateand
improveapplicationstobestmeetbusinessneeds.
Reducing these debts allows the organization to:
❙❙ Minimize application maintenance costs.
❙❙ Increase funding for strategic application
development and IT initiatives.
❙❙ Increase application service levels.
❙❙ Improve customer satisfaction through reduced
outages and slowdowns.
❙❙ Increase employee productivity.
The keys to industrialized zero maintenance
Industrialized zero maintenance requires a platform
to find, categorize and remediate problems in
a repeatable, consistent manner that delivers
predictable, verifiable results. This eliminates the
need to constantly reinvent processes to identify
the sources and costs of application issues, decide
which are most worth addressing and individually fix
multiple issues caused by common causes.
For reducing nondiscretionary spend, the platform
must provide:
❙❙ Integration with existing IT service management
tools to capture tickets and other operational
data to identify normal usage patterns as well as
common problems.
❙❙ Machine learning (ML) to create rules that
automatically recognize issues and categorize
the tickets into technical, functional, operational
and knowledge debts. Such ML should also
categorize the issues as either avoidable (where
permanent fixes are possible) or unavoidable
(where permanent fixes are not possible or may
not provide enough of a return to implement).
❙❙ Based on the debt classification, requests for
the creation of automatic healing processes to
permanently eliminate the root cause of defects
and/or requests for the support team to automate
common, unavoidable remediation chores.
❙❙ Recommendations about which problems
deserve the most attention by estimating the
current costs (the price of the debt) for each
issue and the cost of a permanent fix (the cost to
fix the debt).
❙❙ Governance mechanisms to track the entire
debt lifecycle from identification to creation of
a remediation plan, the status of remediation
efforts and the measurement of benefits.
Cognizant 20-20 Insights
4  /  Industrializing Zero Application Maintenance
For reducing discretionary spend, the platform
must provide:
❙❙ The capturing of application attributes to allow
portfolio analysis, identifying opportunities for
simplifying the IT landscape and modernizing
platforms for greater agility.
❙❙ Categorization of applications into “contain” (low-
criticality applications with high-ticket volumes
that are expensive to maintain or scheduled for
decommissioning), “maintain” (applications of
medium or high criticality that must be retained)
and “invest” (applications of medium to high
importance based on legacy technologies that
require overhaul or reengineering to reduce risk
and grow the business).
❙❙ Recommendations for which transformation
levers to apply to each application, such as
retirement, modernization, cloud migration and
app resiliency.
❙❙ Quantification of the business benefits
generated by each transformation lever.
For delivering business outcomes, the platform
must provide:
❙❙ Tracking of the right key performance indicators
(KPIs) to measure the health of the business
process each application supports.
❙❙ Automatic benchmarking of an organization’s
performance on business KPIs against others in
its industry, presented in an intuitive, easy-to-
use way.
❙❙ “Slice and dice” analytics of application
performance and its effect on the business,
as well as identifying bottlenecks in business
processes.
❙❙ Mechanisms to continually monitor business
KPIs, identify deviations and report on progress of
the remediation of both the business processes
and the applications that support them.

We used Cognizant AppLens™, our platform for gathering, analyzing and presenting the
information required to implement a zero-maintenance strategy, to automatically identify
and categorize the debts in the application portfolio and create automation and healing
tickets to reduce those debts. Using data from this company’s IT Service Management
(ITSM) platform we analyzed tens of thousands of tickets and found close to half caused by
functional debt, with most of the remainder split between technical and operational debt.
We reduced some of these debts and eliminated others through permanent fixes and
enhancement as well as proactive problem management, to increase operational efficiency.
For example, we reduced technical debt by about nine percent through proactive problem
management and performance tuning in data supply chain applications and cut operational
debt by about 5% through automation and self-help utilities and portals.

Getting Started
Creating an industrialized zero application maintenance strategy requires not only the
right technology, but the right organizational culture and processes.
One requirement is executive commitment to fund the underlying platform, and to
ensure subject matter experts contribute their knowledge and experience to the program.
Executive support is also required to fund and emphasize the importance of training on the
why, what and how of a zero-maintenance strategy.
Another requirement is for IT to build alliances with business managers and users to
understand which applications and processes are most critical to them. Such partnerships
will help application maintenance strategists define the desired business outcomes and
map business processes with applications to measure business outcomes and KPIs.
It is also vital to understand the existing applications, as well as the associated monitoring
and diagnostic tools and processes, to access the information essential to a zero-
maintenance strategy. A blueprint of the IT landscape and the relationship of various
components within it helps identify bottlenecks and unmet requirements standing in the
way of zero maintenance.
IT organizations must also establish end-to-end governance to continually manage
the debt within the system, maintain the technical value of the portfolio and deliver
measurable business benefits. While each organization’s needs will differ, governance
approaches we have found useful include:
Quick Take
Cognizant 20-20 Insights
10  /  Industrializing Zero Application Maintenance
❙❙ Ensuring a strong gating mechanism to accept changes into production. A well-
defined service introduction process includes mutually agreed code quality benchmarks
and policies such as allowing no manual maintenance activities in the production
environment, early involvement of the support team in software development to ensure
a closed loop feedback mechanism (the DevOps model1
), and standard processes in
areas such as release documentation and training. A feedback mechanism that tells
developers which patterns of debts they are unwittingly building into their software
helps prevent the creation of future debts.
❙❙ Ongoing monitoring of all debts to ensure they are eliminated or that the necessary
fixes are being automated.
❙❙ Periodic application lifecycle management to assure all applications are delivering
technical and business value. This helps the organization not only “deliver projects
right” but also “deliver the right projects.”
❙❙ Ongoing monitoring of business processes and implementing appropriate
remediation to ensure they meet all required KPIs.

Industrializing Zero Application Maintenance

  • 1. Digital Systems & Technology Industrializing Zero Application Maintenance By applying a rigorous and automated approach to supporting applications, IT organizations can reduce spending, increase repair accuracy, minimize application debt across the portfolio, free up resources for more strategic business imperatives and improve application yield to deliver enhanced business outcomes. Executive Summary CIOs continuously struggle to balance two needs. The first is assuring applications perform with maximum speed and reliability at the lowest cost (i.e., are fit for use). The second is to ensure these applications meet the most pressing needs of the business and stay relevant (i.e., are fit for purpose). They walk this tightrope amid prohibitively high application maintenance costs, rapid technological changes, and an unforgiving and highly competitive global economy. Ideally, CIOs can meet both these demands if applications run on “auto pilot” and deliver intended business outcomes without manual intervention and related maintenance costs. We call this state of maturity zero maintenance. While it may be very difficult to achieve, implementing a zero-maintenance strategy helps organizations drive quantum reductions in cost and increased business value. Cognizant 20-20 Insights November 2019
  • 2. Zero maintenance strategies typically focus on: ❙❙ Reducing technical debts, which frees cash and allows organizations to bootstrap investments on strategic initiatives. ❙❙ Improving the technical value of the portfolio by modernizing the application, thus making it digital-ready. ❙❙ Addressing critical bottlenecks in the applications that support business processes by improving application throughput, which in turn enhances business performance. Zero maintenance delivers the greatest benefits when it is industrialized. This means establishing a structured, ongoing process to identify and categorize technological debt that applications incur over time and minimizing them by quickly fixing defects, improving technical infrastructure and automating as much of the required remediation as possible. Such an industrialized process should also identify and optimize the workflows that are most critical to the business to deliver improved outcomes. This white paper describes the importance of industrialized zero maintenance, its key components and best practices for achieving it. Businesses that bring rigor to zero maintenance can apply cost savings to fund more strategic initiatives while improving customer satisfaction and employee productivity.

  • 3. Cognizant 20-20 Insights 3  /  Industrializing Zero Application Maintenance The perpetual IT operations challenge From the day they are put into production, applications begin incurring four kinds of debt: ❙❙ Technical debt, caused by substandard code and aging platforms, leading to outages, slowdowns and other service issues. ❙❙ Functional debt, caused by a failure to update software to meet new business requirements, leading to change requests. ❙❙ Operational debt, caused by inefficient operations management and a lack of administrative tools, leading to excess manual effort, configuration errors and increased cost. ❙❙ Knowledge debt, caused by insufficient documentation or a lack of user training, which increases support calls, tickets and costs. Through proven, documented and reliable processes, an industrialized zero maintenance strategy can minimize both kinds of effort: ❙❙ Nondiscretionary effort required to keep applications and the business running. ❙❙ Discretionaryeffortrequiredtoupdateand improveapplicationstobestmeetbusinessneeds. Reducing these debts allows the organization to: ❙❙ Minimize application maintenance costs. ❙❙ Increase funding for strategic application development and IT initiatives. ❙❙ Increase application service levels. ❙❙ Improve customer satisfaction through reduced outages and slowdowns. ❙❙ Increase employee productivity. The keys to industrialized zero maintenance Industrialized zero maintenance requires a platform to find, categorize and remediate problems in a repeatable, consistent manner that delivers predictable, verifiable results. This eliminates the need to constantly reinvent processes to identify the sources and costs of application issues, decide which are most worth addressing and individually fix multiple issues caused by common causes. For reducing nondiscretionary spend, the platform must provide: ❙❙ Integration with existing IT service management tools to capture tickets and other operational data to identify normal usage patterns as well as common problems. ❙❙ Machine learning (ML) to create rules that automatically recognize issues and categorize the tickets into technical, functional, operational and knowledge debts. Such ML should also categorize the issues as either avoidable (where permanent fixes are possible) or unavoidable (where permanent fixes are not possible or may not provide enough of a return to implement). ❙❙ Based on the debt classification, requests for the creation of automatic healing processes to permanently eliminate the root cause of defects and/or requests for the support team to automate common, unavoidable remediation chores. ❙❙ Recommendations about which problems deserve the most attention by estimating the current costs (the price of the debt) for each issue and the cost of a permanent fix (the cost to fix the debt). ❙❙ Governance mechanisms to track the entire debt lifecycle from identification to creation of a remediation plan, the status of remediation efforts and the measurement of benefits.
  • 4. Cognizant 20-20 Insights 4  /  Industrializing Zero Application Maintenance For reducing discretionary spend, the platform must provide: ❙❙ The capturing of application attributes to allow portfolio analysis, identifying opportunities for simplifying the IT landscape and modernizing platforms for greater agility. ❙❙ Categorization of applications into “contain” (low- criticality applications with high-ticket volumes that are expensive to maintain or scheduled for decommissioning), “maintain” (applications of medium or high criticality that must be retained) and “invest” (applications of medium to high importance based on legacy technologies that require overhaul or reengineering to reduce risk and grow the business). ❙❙ Recommendations for which transformation levers to apply to each application, such as retirement, modernization, cloud migration and app resiliency. ❙❙ Quantification of the business benefits generated by each transformation lever. For delivering business outcomes, the platform must provide: ❙❙ Tracking of the right key performance indicators (KPIs) to measure the health of the business process each application supports. ❙❙ Automatic benchmarking of an organization’s performance on business KPIs against others in its industry, presented in an intuitive, easy-to- use way. ❙❙ “Slice and dice” analytics of application performance and its effect on the business, as well as identifying bottlenecks in business processes. ❙❙ Mechanisms to continually monitor business KPIs, identify deviations and report on progress of the remediation of both the business processes and the applications that support them.

We used Cognizant AppLens™, our platform for gathering, analyzing and presenting the information required to implement a zero-maintenance strategy, to automatically identify and categorize the debts in the application portfolio and create automation and healing tickets to reduce those debts. Using data from this company’s IT Service Management (ITSM) platform we analyzed tens of thousands of tickets and found close to half caused by functional debt, with most of the remainder split between technical and operational debt. We reduced some of these debts and eliminated others through permanent fixes and enhancement as well as proactive problem management, to increase operational efficiency. For example, we reduced technical debt by about nine percent through proactive problem management and performance tuning in data supply chain applications and cut operational debt by about 5% through automation and self-help utilities and portals.

  • 9. Cognizant 20-20 Insights 9  /  Industrializing Zero Application Maintenance Getting Started Creating an industrialized zero application maintenance strategy requires not only the right technology, but the right organizational culture and processes. One requirement is executive commitment to fund the underlying platform, and to ensure subject matter experts contribute their knowledge and experience to the program. Executive support is also required to fund and emphasize the importance of training on the why, what and how of a zero-maintenance strategy. Another requirement is for IT to build alliances with business managers and users to understand which applications and processes are most critical to them. Such partnerships will help application maintenance strategists define the desired business outcomes and map business processes with applications to measure business outcomes and KPIs. It is also vital to understand the existing applications, as well as the associated monitoring and diagnostic tools and processes, to access the information essential to a zero- maintenance strategy. A blueprint of the IT landscape and the relationship of various components within it helps identify bottlenecks and unmet requirements standing in the way of zero maintenance. IT organizations must also establish end-to-end governance to continually manage the debt within the system, maintain the technical value of the portfolio and deliver measurable business benefits. While each organization’s needs will differ, governance approaches we have found useful include: Quick Take
  • 10. Cognizant 20-20 Insights 10  /  Industrializing Zero Application Maintenance ❙❙ Ensuring a strong gating mechanism to accept changes into production. A well- defined service introduction process includes mutually agreed code quality benchmarks and policies such as allowing no manual maintenance activities in the production environment, early involvement of the support team in software development to ensure a closed loop feedback mechanism (the DevOps model1 ), and standard processes in areas such as release documentation and training. A feedback mechanism that tells developers which patterns of debts they are unwittingly building into their software helps prevent the creation of future debts. ❙❙ Ongoing monitoring of all debts to ensure they are eliminated or that the necessary fixes are being automated. ❙❙ Periodic application lifecycle management to assure all applications are delivering technical and business value. This helps the organization not only “deliver projects right” but also “deliver the right projects.” ❙❙ Ongoing monitoring of business processes and implementing appropriate remediation to ensure they meet all required KPIs.
