Thesis (MPhil)--University of Stellenbosch, 2004. / ENGLISH ABSTRACT: The effort to achieve quality is the largest component of software cost. Software testing is
costly - ranging from 50% to 80% of the cost of producing a first working version. It is
resource intensive and an intensely time consuming activity in the overall Systems
Development Life Cycle (SDLC) and hence could arguably be the most important phase of
the process. Software testing is pervasive. It starts at the initiation of a product with nonexecution
type testing and continues to the retirement of the product life cycle beyond the
post-implementation phase.
Software testing is the currency of quality delivery. To understand testing and to improve
testing practice, it is essential to see the software testing process in its broadest terms – as
the means by which people, methodology, tools, measurement and leadership are integrated
to test a software product.
A knowledge approach recognises knowledge management (KM) enablers such as
leadership, culture, technology and measurements that act in a dynamic relationship with KM
processes, namely, creating, identifying, collecting, adapting, organizing, applying, and
sharing. Enabling a knowledge approach is a worthy goal to encourage sharing, blending of
experiences, discipline and expertise to achieve improvements in quality and adding value to
the software testing process.
This research was developed to establish whether specific knowledge such as domain
subject matter or business expertise, application or technical skills, software testing
competency, and whether the interaction of the testing team influences the degree of quality
in the delivery of the application under test, or if one is the dominant critical knowledge area
within software testing. This research also set out to establish whether there are personal or
situational factors that will predispose the test engineer to knowledge sharing, again, with the
view of using these factors to increase the quality and success of the ‘testing phase’ of the
SDLC. KM, although relatively youthful, is entering its fourth generation with evidence of two
paradigms emerging - that of mainstream thinking and that of the complex adaptive system
theory. This research uses pertinent and relevant extracts from both paradigms appropriate
to gain quality/success in software testing. / AFRIKAANSE OPSOMMING: By verre die grootste komponent van sagte ware koste is dié verwant aan
kwaliteitsversekering. Toetsing van sagte ware is koste intensief en verteenwoordig tussen
50% en 80% van die kostes om ‘n beta weergawe vry te stel.
Die toetsing van sagte ware is nie alleenlik duursaam nie, maar ook arbeidintensief en ‘n
tydrowende aktiwteit in die sagte ware ontwikkelings lewensiklus en kan derhalwe gereken
word as die mees belangrike fase. Toetsing is deurdringend – dit begin by die inisiëring van
‘n produk deur middel van nie-uitvoerende tipe toetsing en eindig by die voleinding van die
produklewensiklus na die implementeringsfase.
Sagte ware toetsing word beskou as die geldwaarde van kwalitatiewe aflewering. Om
toetsing ten volle te begryp en die toepassing daarvan te verbeter, is dit noodsaaklik om die
toetsproses holisties te beskou – as die medium en mate waartoe mense, metodologie,
tegnieke, meting en leierskap integreer om ‘n sagte ware produk te toets.
‘n Benadering gekenmerk deur kennis erken die dinamiese verhouding waarbinne
bestuurselemente van kundigheid, soos leierskap, kultuur, tegnologie en maatstawwe
reageer en korrespondeer met prosesse van kundigheid, naamlik skep, identifiseer,
versamel, aanpas, organiseer, toepas en meedeel. Die fasilitering van ‘n benadering
gekenmerk deur kennis is ‘n waardige doelwit om meedeling, vermenging van ervaringe,
dissipline en kundigheid aan te moedig ten einde kwaliteit te verbeter en waarde toe te voeg
tot die proses van safte ware toetsing.
Die doel van hierdie navorsing is om te bepaal of die kennis van ‘n spesifieke onderwerp,
besigheidskundigheid, tegniese vaardighede of die toepassing daarvan, kundigheid van
sagte ware toetsing, en/of die interaksie van die toetsspan die mate van kwaliteit beïnvloed,
of een van voorgenoemde die dominante kritieke area van kennis is binne die konteks van
sagte ware toetsing. Die navorsing beoog ook om te bepaal of daar persoonlike of
situasiegebonde fakfore bestaan wat die toetstegnikus vooropstel om kennis te deel, weer eens, met die oog om deur middel van hierdie faktore kwaliteit te verbeter en die toetsfase
binne die sagte ware ontwikkelingsiklus suksesvol af te lewer.
Ten spyte van die relatiewe jeudgigheid van die bestuur van kennis, betree dit die vierde
generasie waaruit twee denkwyses na vore kom – dié van hoofstroom denke en dié van
ingewikkelde aangepaste stelselsdenke. Hierdie navorsing illustreer belangrike en toepaslike
insette van beide denkwyses wat geskik is vir meedeling van kennis en vir die bereiking van
verbeterde kwaliteit / sukses in sagte ware toetsing.
