PeopleTools ATT: Customizing PeopleSoft for a Global
PeopleTools ATT functions as the core technological backbone underpinning its large-scale PeopleSoft applications, specifically handling Human Resources and financial data for a workforce that spans hundreds of thousands of employees globally. PeopleTools is not the application itself, but the suite of proprietary development and customization tools—including Application Designer, PeopleCode, and Application Engine—that AT&T’s internal IT teams use to tailor PeopleSoft to their unique, highly complex organizational structures, regulatory requirements, and business processes. This level of customization is essential for an enterprise of AT&T’s size, which requires non-standard workflow approvals, highly specific security configurations, and unique data structures.
The Role of PeopleCode and Custom Logic
A significant application of PeopleTools ATT within AT&T involves the creation of PeopleCode, the object-oriented programming language native to PeopleSoft. Due to the company’s vast operational footprint and historical mergers, standard PeopleSoft processes often fall short. AT&T developers utilize PeopleCode to implement custom business logic, such as complex salary calculations that adhere to various state and international laws, specialized benefits enrollment rules, or intricate organizational chart roll-ups that reflect the company’s matrixed management structure. This ensures the PeopleSoft system accurately mirrors AT&T’s unique HR policies and compliance requirements.
Application Designer for Interface and Data Structure
The Application Designer is the integrated development environment (IDE) component of PeopleTools. AT&T relies on this tool to modify data structures (records and fields), customize user interfaces (pages and components), and build new application components entirely. For example, to manage the diverse roles within the company, from field technicians to corporate executives, AT&T may have developed custom record definitions in the Application Designer to track specialized certifications or project assignments that are not standard features in the base PeopleSoft HCM product.
Managing Security and Access Control
Given the sensitive nature of employee and financial data, security implementation is a critical function of PeopleTools at AT&T. PeopleTools enables the configuration of highly granular, role-based security. This ensures that managers can only view the data of their direct reports, HR generalists are limited to specific regional data, and payroll specialists have access only to the necessary financial components. The security layers are typically complex, involving custom permission lists and roles designed to align with AT&T’s internal compliance and audit requirements.
Integrations and Data Flow with External Systems
As a major corporation, AT&T’s PeopleSoft environment is not isolated; it must constantly exchange data with dozens of other enterprise systems—from general ledger and data warehousing platforms to time and labor systems used by field staff. PeopleTools ATT facilitates this through components like the Integration Broker and Application Engine. The Integration Broker manages the real-time or near-real-time flow of data, ensuring, for example, that a change in an employee’s job code in PeopleSoft is immediately updated in the billing system or the internal directory.
Application Engine for Batch Processing
For high-volume, repetitive tasks, PeopleTools ATT extensively uses the Application Engine (AE), a PeopleTools component for batch processing. These AE programs run critical processes, such as:
-
Mass updates of employee benefits at the start of a new fiscal year.
-
Nightly calculations for pensions or accruals.
-
Generation of mass communications to employees regarding policy changes.
This automation is vital for handling the sheer scale of transactions inherent in managing a massive workforce.
Upgrades and Maintenance Challenges
Maintaining the PeopleSoft system at AT&T presents significant challenges, largely due to the high level of PeopleTools ATT customization. Every major PeopleSoft upgrade or patch release requires the AT&T technical teams to execute extensive “retrofitting”—modifying their custom PeopleCode and objects to work with the new PeopleSoft version. This process is time-consuming and labor-intensive, often requiring specialized PeopleTools consultants to manage the complexity and ensure business continuity during the transition.
The Transition to Fluid UI
More recently, the focus within PeopleTools ATT has shifted toward the Fluid User Interface (UI). AT&T’s strategy includes adopting Fluid UI to modernize the employee experience, making self-service functions (like applying for leave or changing personal data) more intuitive and mobile-friendly. The transition involves a major PeopleTools effort to redesign classic pages using Fluid components, ensuring the custom logic built over decades continues to function seamlessly in the new responsive environment.
Career and Expertise Demand
The continued use and customization of PeopleSoft applications mean that there is an ongoing, high demand within AT&T for specialized IT professionals with deep PeopleTools ATT expertise. These roles, which include PeopleSoft Developers, System Analysts, and Testers, require an intricate understanding of the PeopleTools framework, specific AT&T business processes, and compliance requirements, underscoring the platform’s strategic importance to the organization.
Strategic Importance of PeopleTools to AT&T
Ultimately, the utilization of PeopleTools ATT is not merely a technical detail; it is a strategic necessity for AT&T. The framework allows the company to rapidly adapt its mission-critical HR and financial systems to changing business needs, mergers, divestitures, and evolving global regulations, providing the flexible foundation needed to manage its massive, dynamic human capital operations effectively.
