Comparison of ISO/IEC 20000 with ASL and BiSL

Both ISO/IEC 20000 and ASL offer guidance for IT Service Providers, ISO/IEC 20000 giving broad guidance for IT Service Management and ASL focusing on the Application Management area. In this white paper, Machteld Meijer and Mark Smalley explain the relevance of ASL and BiSL in relation to ISO/IEC 20000. Positioning these three standards in a demand-supply chain illustrates the areas to which they contribute.

Procesbeschrijving Toetsen en Testen

In de beschrijving van het proces “Toetsen & testen” in het BiSL framework wordt het Toetsen minder expliciet belicht dan het Testen.

Testen gebeurt achteraf, na een inspanning. Toetsen gaat vooraf aan die inspanning en kan veel onnodig werk a.g.v. onvolledig begrip en onjuiste aannames voorkomen.
Zowel het BiSL framework, als deze best practice expliciteren vooral de procesgang van het Testen. Toetsen blijft impliciet.
