CASE STUDY:

New Interface Resolves Timing Incompatibility with Wireless Connectivity

CUSTOMER:
TASK:
Federal Housing Finance Agency (FHFA)
Network Engineering, Information Security

Customer Mission:

In the wake of the 2008 housing mortgage financial crisis, the Federal Government established the FHFA to consolidate and centralize regulatory authority over Fannie Mae, Freddie Mac, and the Federal Home Loan Banks. The Agency oversees the management of more than $5.5 trillion in mortgage-backed securities and debt. FHFA oversight directly and indirectly impacts the welfare of virtually all American homeowners and investors.

The Challenge:

FHFA staff travel frequently to conduct audits, inspections, and investigations to ensure the effectiveness of the regulations and the continued stability of the housing mortgage market. While traveling, they depend on tablets and other mobile devices for communications and access to applications, email, and real-time data from the Agency’s back office systems. This mobile access provides real-time situational awareness, critical in detecting early warning signs of possible non-compliance or fraud. After a recent technology refresh initiative, which included new tablet computers, many users experienced email synchronization issues when connecting through one specific wireless carrier. This lack of access critically jeopardized the FHFA’s mission.

Powertek's Solution:

FHFA worked with the mobile carrier’s technicians for several weeks without success. FHFA’s management staff tasked Powertek to evaluate the enigma and develop a solution that would allow staff to access the network from mobile devices while traveling. Following our ISO 9001-based Quality Management best practices, Powertek formed a tiger team of networking and telecommunications experts knowledgeable in Office 365 and mobile technologies to investigate the root cause. Our team quickly recreated the failure scenario, tracing the cause to an erratic timing incompatibility between the carrier network signaling and the tablets’ wireless interface. Powertek engineers developed a workaround procedure that helped remove the timing variability and ensure reliable wireless connections for FHFA users.

Benefits:

  • Timely delivery of emails and notifications to traveling staff
  • Connectivity ability via tablets to enable access to the Agency’s back office systems
  • Increased productivity for traveling staff through new wireless interface
  • Ability for FHFA auditors and inspectors to detect early warning signs of non-compliance or fraud

Automation Tool Streamlines Development

CUSTOMER:
TASK:
Department of Housing and Urban Development (HUD)
Configuration Management, Software Development

Customer Mission:

HUD’s mission is to ensure that the American public has access to safe and affordable housing and to promote the growth of vibrant communities across our nation. The Agency is responsible for operating multiple programs that oversee and manage applications, loans, safety standards, reporting, and regulatory compliance. HUD’s programs rely on software applications and information sharing intra-Agency and with other Federal Agencies. Its technologies enable HUD to ensure timely and accurate financial transactions, case processing, and reporting.

The Challenge:

Due to the large number of disparate systems and more than 12 development contractors, HUD faced challenges in responding quickly to customer needs, housing market conditions, and Congressional regulatory changes. Major updates to the software applications and databases could only take place twice a year. This infrequent software release cycle hindered HUD’s business programs and business offices in making timely decisions, in assessing the effectiveness of Agency initiatives, and in responsively supporting its customers nationwide. The Agency required a solution to standardize the development process, align the activities of all contractors, and support more frequent software releases, as often as 12 times per year.

Powertek's Solution:

Powertek recognized the criticality of HUD’s mission and the schedule challenges it faced for software updates. We developed a methodology to streamline the update process, provide consistency across subsystems, and add value to the customer. We designed and created CADRE, our solution to HUD’s challenge. CADRE is a Powertek proprietary tool developed in our engineering laboratory that automates testing, reduces the test cycles for new software and hardware technologies, and eliminates manual operations. CADRE aligns the various development teams by providing consistency across all subsystems. Fully automated, CADRE runs unattended 24/7/365 to provide steady-state operation, eliminating errors, enabling build and deployment rollouts in half the time, and providing a standardized process for change management. Since CADRE runs unattended, Powertek was able to repurpose software developers to accomplish other tasks, allowing us to achieve more for HUD within the program’s original budget.

Benefits:

  • 50% reduction in builds and deployments enabling expedited rollouts of new technologies
  • 100% increased productivity of software development teams, allowing the Government to get more done within the defined budget
  • 50% reduced production time, resulting in a significant cost savings to the Government
  • 100% error-free builds and deployments, leading to increased end-user satisfaction
