Recensie(s)

De Swart uit hoe belangrijk 'requirements' zijn. Logisch omdat het hier gaat om de benodigdheden en vereisten die het ICT-product (bijvoorbeeld software program) moet bevatten om zodoende te voldoen in kwalitatief opzicht. Met andere woorden: als het product onvoldoende kwaliteit biedt, heeft de organisatie er niets of weinig aan. De auteur legt nogal omstandig uit wat een ICT-product moet kunnen. En uiteraard vernemen we ook hoe de gevolgen kunnen zijn als het product niet op de vereisten (requirements) ingaat (foute investering!). In het boek wordt gedetailleerd uiteengezet welke processen er denkbaar zijn die de kwaliteit van het ICT-product vergroten. Het is geen gemakkelijk boek geworden. Voor specialisten in ICT en -ontwikkeling en binnen de ondernemingen zijn er vele aspecten van belang. De bedoeling van het boek snijdt ook zeker hout: te veel organisaties hebben tonnen tot miljoenen verloren bij foute beslissingen bij het aanschaffen van ICT-bedrijfsmiddelen. Derhalve een specialistisch, maar praktisch werk. Met talrijke schema's, een aantal bijlagen, waaronder een verklarende woordenlijst, een literatuuropgave en een check in. Verder wordt verwezen naar een vrij toegankelijke site met onder meer informatie over opleidingen en aanvullend materiaal op dit boek.
