1. They focus only on how to documented the systems before it defined and aligned with the business process of the organization.
Most of the organization that apply certification would get busy with the documentation they need to adopt in fulfiling all requirements. It is quite often that those documentation though not wrong in definition, it just not aligned with the actual system within the organization.
2. That system then applied through organization before conducting systems review within organization.
Though they aligned and well defined, to catch up the deadline, they skip the process of systems review in ensuring the system documented would effectively implemented within the organization. The review is very important to see how the system control at point of execution. In spite of how good the system documented but losing its effectiveness at point of execution could bring the organization lose their effectiveness.
3. They do not monitor and follow up the quality objective accordingly and/or set it in no SMART way, i.e. specific, measurable, achievable, realistic and timely.
Key performance indicators (KPI) defined in quality objectives are the most important things in measuring how effective the organization was. They must be sort, 3 to 5 objective are enough. Less is better. The big mistake is to set as many quality objectives as it can. It just make them not focus on their KPI. When they set it correctly, they often do not follow SMART way, meaning the objectives are not specific, difficult to measure, hard to achieve, not realistic and no time oriented.
When those 3 things can be handle properly, you should get more benefits in applying ISO 9000 quality management system, not just certified but fail in improving your operation performance.
