There has been performed the analysis of techniques used in process of providing quality in computerized information systems. The following techniques have been described: - review of the system, - supervision of the system, audit of the system, inspection, - testing. The purpose of review is providing the correspondence of designed system with specification. The purpose of the system supervision is discovering and identifying its elements defects. The audit is led from the point of view of the system correspondence: verification with processed in act of designing, chosen standards, like procedure norm and instruction. The system supervision is based on principle that the other person, not the system creator, performs review of the documentation as well as searches for made errors. The purpose of the testing is discovering the errors in researched object that might be: the project of system, computerized information system, its part or prototype. Testing occurs in each cycle of life of computerized information system; it is a variant of industrial quality control. Majority of information products functions is not a subject of industrial quality tests. It results from the fact that software production most often is individual not serial or mass - produced. Therefore the methods of industrial quality controls do not apply to software. Each program owns unique combination of functions that differ. Big amount of software functions causes that amount of those combinations grows and very often is impossible to definite. Most often only 10% of program is the subject of verification. The number of applicable methods to provide the quality in computerized information systems is considerably smaller than system designing methods. Prevailing techniques do not provide obtaining high quality computerized information system. They do not guarantee obtainment of reliable computerized information system. Predominately used criterion is called system is good enough. Therefore verification of computerized information system quality is indispensable i.e. its control. The research made in industry shows that errors occur even in simple industrial production. Moreover only small part of quality estimation methods used in industry are applicable to estimate the quality of computerized information system. Inspection and testing are most often used methods of supervising.
