    ABSTRACT: Lean principles have attracted the attention of software development companies due to their potential to improve competitiveness. However, the application of such principles in the software domain is still in its infancy. This paper presents a proposal for adapting the Lean Enterprise Self-Assessment Tool (LESAT) to guide the transformation of software development companies toward Lean. LESAT, developed by the Lean Advancement Initiative (LAI) at the Massachusetts Institute of Technology (MIT), has been widely used in other domains. In this study, concepts and expressions of LESAT were analyzed and mapped to software development following the ISO/IEC 12207 standard. Seven assessment items concerning life-cycle processes were modified from the original LESAT. The modified LESAT for software was compared with a lean assessment approach called "Lean amplifier, " which has been developed and successfully used in practice by Ericsson R&D in Finland. The results indicated that LESAT may complement lean assessment in the software domain at enterprise level, involving the entire value stream. Moreover, they clearly emphasized the role of leadership in the transformation.

    ABSTRACT: Persistent controversy underlies the functional roles of specific p38 MAPK isoforms in cardiac biology and regulation of hypertrophy-associated genes. Here we show that adenoviral gene transfer of p38β but not p38α increased B-type natriuretic peptide (BNP) mRNA levels in vitro as well as atrial natriuretic peptide mRNA levels both in vitro and in vivo. Overexpression of p38α, in turn, augmented the expression fibrosis-related genes connective tissue growth factor, basic fibroblast growth factor and matrix metalloproteinase-9 both in vitro and in vivo. p38β-induced BNP transcription was diminished by mutation of GATA-4 binding site, whereas overexpression of MKK6b, an upstream regulator of p38α and p38β, activated BNP transcription through both GATA-4 and AP-1. Overexpression of MKK3, upstream regulator of p38α, induced BNP transcription independently from AP-1 and GATA-4. These data provide new evidence for diversity in downstream targets and functional roles of p38 pathway kinases in regulation of hypertrophy-associated cardiac genes.
