Application Assessment
Establishing what the application contains — rules, customization, dead configuration — which is usually more than anyone expects.
Pega Modernization & Optimization
Upgrade, untangle and tune Pega applications that have become hard to change.
Overview
Long-running Pega applications accumulate: rules nobody can attribute, custom code that bypasses the model, versions left behind because upgrading felt risky. Nextherrion assesses what is there, removes what is not earning its keep, and brings applications back to a state where the platform's own capability does the work again.
Application assessment, version upgrades, rule rationalization, performance tuning and the ongoing support that keeps an estate healthy.
Version Upgrades
Moving to a supported release with impact assessed in advance, so upgrade is a planned exercise rather than a deferred risk.
Rule Rationalization
Consolidating overlapping and superseded rules, which is what makes an application comprehensible enough to change safely.
WHAT WE DO
Modernization & Optimization Services We Offer
Custom Code Reduction
Replacing customization with platform capability where it now exists, reducing what has to be revalidated at every upgrade.
Performance Optimization
Addressing rule resolution, database access and case volume issues, which degrade as applications and data grow.
Architecture Review
Reviewing application structure and reuse, since layering decisions made early determine how much later work costs.
Technical Debt Remediation
Sequenced cleanup that keeps the application running throughout, rather than a freeze while it is put right.
Ongoing Support
Support and enhancement capacity for applications in production, where that skill is not available in-house.
OUTCOMES
What Modernization Changes
Applications rarely fail outright. They accumulate until change becomes risky, and the organization quietly stops asking for changes.
- Running a supported version
- Rules that can be attributed
- Less custom code to revalidate
- Performance restored
- Change that is safe again
- Upgrades that stay routine
FAQ
Frequently Asked Questions
We are several versions behind. Is that a problem?
It becomes one — support, security fixes and platform capability all depend on it. The longer it is deferred, the larger the eventual upgrade.
Will upgrading break our customizations?
That is what impact analysis establishes first. Heavy customization is where upgrade effort concentrates, which is also the argument for reducing it.
Can we clean up without stopping the application?
Yes. Work is staged and regression-tested so the application keeps running, rather than freezing while it is put right.
How do we know which rules are unused?
Usage analysis and dependency tracing. Removing rules on assumption is how a cleanup becomes an outage.
The application has become slow. Is that fixable?
Usually. Slowness in mature applications typically traces to rule resolution, data volume or unindexed access, all of which respond to targeted work.
Should we rebuild instead?
Rarely. The application encodes years of process decisions that exist nowhere else, which a rebuild discards and then rediscovers expensively.
