If patch and change management is poorly accepted within an organisation or if the people involved communicate poorly, this can lead to processing delays and incorrect decisions related to change requests. This may reduce the organisation's security level and seriously impair its IT operations. In any case, poor communication results in inefficient change processes because they require an excessive amount of time and resources. This has adverse effects on an organisation's ability to react and may, in extreme cases, result in vulnerabilities or the inability to attain important business objectives.
