This booklet explains how local communities can organize and structure their one-stop centers so that business is viewed as a customer of the system. The introduction provides an overview of the booklet's development and purpose. The following key attributes underpinning a workforce investment system that views business as its customer are discussed: market driven; customer focused; skill based; and results oriented. The following strategies for assessing business needs as a first step toward establishing a market-driven system are outlined: (1) partner with business to operate one-stop centers; (2) establish workforce board committees and surveys; (3) establish industry-specific advisory committees; and (4) involve established employer organizations and business coalitions. The remaining sections examine the following items: (1) the key elements of customer-focused one-stop centers (business partnerships; comprehensive employer services; training targeted to identified business needs; business outreach; a professional environment); (2) guidelines for delivering industry-recognized training (identify specific industry trends and skill requirements; set high standards for education and training providers; use national or state skill standards when available; offer employer-based certifications); and (3) strategies for enhancing accountability (set new standards for employer satisfaction and continuous improvement; publicly disclose performance of training providers; assess overall system performance based on specific measurable outcomes).
