Economic Programs Directorate
  • Measure and profile businesses and government
    organizations of the United States
  • Nine organizations in the directorate
  • Five subject matter divisions
  • Four directorate wide support divisions

2007 Economic Census
  • Economic Census is conducted every 5 years
  • Data collection focuses on years ending in 2 and
    7
  • Questionnaire mailout occurs in December of the
    collection year
  • Data processing and dissemination activities
    take place for 3 years following mailout
  • Covers over 23 million business establishments
  • Core Census Programs
  • Manufactures
  • Mineral Industries
  • Construction Industries
  • Retail and Wholesale Trade
  • Service Industries
  • Finance, Insurance, and Real Estate
  • Transportation, Communication, and Utilities
  • Use of enterprise systems to collect, process
    and disseminate data
  • There are approximately 1700 separate data
    releases over a 2.5 year period

Quality Management and the 2007 Economic Census
  • Short-Term Goals
  • Ensure adherence to Statistical Standards
  • Ensure adherence to Project Management process
  • Ensure adherence to Software Development process
  • Adherence measured through quality audits
  • Long-Term Goals
  • Improve product quality
  • Improve process quality

Role of Quality Audits in Quality Management
  • Evaluation of work products and processes based
    on established standards
  • Documentation of audit results
  • Communication with project manager, project team
    and SQA staff
  • Reporting of noncompliance issues to senior
    management as needed
  • Tracking of noncompliance issues to closure
  • Documentation of status of audit process
  • Evaluation of audit effectiveness against
    objectives of SQA program

6

Organization to Conduct Quality Audits
  • Separate Staff Dedicated to Quality Audits
  • Independently Supervised
  • Objective Review of Management Products Produced
  • Objective Review of Activities Performed
  • Feedback from QA Staff to Manager
  • Private Audit Process

Macro Processing and Dissemination Processes
  • Macro Processing and Dissemination -- Phase 3 of
    the Economic Census -- involves all processes
    related to the macro analysis and dissemination
    of the Economic Census data and its related
    programs.
  • There are 11 major IT systems
  • Each system is supported by a cross-divisional
    team comprised of staff from
  • EPCD Provides the Business Analysts and the
    Project Managers. Often times, both of these
    roles are played by the same individual.
  • Economic Statistical Methods and Programming
    Division (ESMPD) Provides the programming and
    system development staff.
  • Subject matter areas (business units) Provides
    the subject matter (data) experts and system
    users.
  • These teams strive to maintain, and if possible,
    improve the standardization of these systems.

Quality Audits and the Macro Processing and
Dissemination Team Process
  • In the conjunction with ESMPD, EPCD developed
    the Macro Processing and Dissemination Team
    Process.
  • Re-used best practices from the 2002 Economic
    Census and used them to develop our own software
    development methodology.
  • Implemented a minimum process for software
    development methods and tools.
  • Developed standardized tools and procedures that
    would be used for all macro teams.
  • Ensured clear understanding of roles and
    responsibilities for all team members.
  • Throughout the project lifecycle, work products
    and processes are reviewed to ensure compliance
    to agreed upon standards (SQA Audits).

Current Status
  • Status of the 2007 Economic Census
  • All phase 3 projects are currently in
    development and testing.
  • Several of the project teams have made
    preliminary deliveries of production
    applications.
  • All systems are expected to be ready on or
    before October 31, 2008.
  • Status of SQA activities
  • We have completed the first two cycles of SQA
    evaluations for all 11 IT systems. Neither of
    these two cycles identified noncompliance issues.
  • Third cycle of evaluations is scheduled to be
    complete July 22, 2008.
  • Project teams have conducted lessons learned
    sessions to gain feedback.

14
Successes and Areas for Improvement for SQA
  • Successful initiatives from our progress to
    date
  • Clearly defined project processes and products
    as well as individual roles help to reduce
    ambiguity of tasks.
  • Utilization of standard templates and documents
    reduces the learning curve for team members who
    serve on several teams.
  • Independent assessment provides valuable feedback
    all during the project.
  • Initiatives and processes that could be more
    effective in subsequent projects
  • Auditing process and products for presence only
    does not offer much value.
  • Having the SQA staff trained to review the
    contents of each document and not just the
    template that is used, would offer more value.
  • After several rounds of auditing with no
    noncompliance issues, it might be acceptable to
    only audit a subset of projects.
  • When established business processes have been
    working well to date, focus resources on other
    aspects of the process.
  • All team members should be included in the
    methodology development process to ensure
    consideration of work from all viewpoints is
    considered.
  • Improved communication plans would make
    everything flow much easier.

Quality Management Lessons Learned
  • Quality Management is a continuous process. It
    cannot be turned on for the Economic Census and
    turned off for all projects between Censuses.
  • Focus should be on the content of documents
    reviewed in the audit and not just the presence
    of that document.
  • Clear, specific, detailed standards must be
    developed early to get everyone educated on the
    process and its expectations.
  • Independent review and reporting of adherence to
    standards is of great value.
  • Goal of quality audits is to tell senior
    management whether a project is adhering the
    standards. Failure to adhere to standards should
    be viewed as a teaching opportunity to improve
    skills.
  • Planning and training for project management
    should include quality assurance processes and
    staff at all stages.
  • Decisions on tools used for project management
    should be made early . Some quality problems
    occur because we do not make the best use of
    tools available.

16
Next Steps
  • Receive feedback from all participants during
    each phase of the project and make modifications
    where feasible.
  • Continue to carry out each project and perform
    an evaluation of the Macro Processing and
    Dissemination Team Process upon the closeout of
    all projects.
  • Upon final evaluation, make modifications to the
    process and begin planning phases for the next
    cycle of projects to be audited.
