Conclusions

Overall the experts found the system to be fairly usable. The conclusions that are derived from the answers under each of the different usability areas are as follows:

Learnability
The experts found the system very easy to learn, the system is uncluttered and that information is easy to find. A minimalist approach makes the system clear and easy to navigate. It seemed that the majority of the experts did not feel the need to refer to the Instruction manual as the system is self explanatory. Those that did, found it useful in explaining more of the payroll query process as oppose to the system itself. The navigation bar on the left made navigation of the system very easy.

Efficiency
It appears that the system is very efficient with only one noted delay from an expert.

Memorability
Clarity and a logical structure made the system easy to remember. Functionality consistently located between pages made the system fairly intuitive. The navigational structure and page layout allowed the experts to build a spatial representation of system making it easier to remember. The familiar menu style also helped the experts recall how to use the system.

Errors
More validation could be added to the submit query form to ensure data integrity. The experts found that highlighting of incomplete fields is good at alerting the user to missing data, although a more desriptive error message may be useful.

Satisfaction
The majority of the experts enjoyed using the system. The simplicity and ease of use made using the system an enjoyable experience. The colours and feel of the system were easy on the eyes. The colours were found to be modern and clear.

Control
The experts generally felt that they were in control of the system at all times. One expert expressed concern regarding the movement of queries from new to pending without asking the user, this is related more to the payroll query process as opposed to the usability of the system.

Skills
The system was found to be professional by the experts, the standardised layout and familiar navigation are the main reasons for this. The payroll experts found that the system either did enhance their skills or would given time. The personalisation features of the system makes the users feel more valued and appreciate the role played within the department.

Privacy
Unawareness of the data protection act (DPA) with some of the experts made feedback in this area less reliable than others. The experts did feel confident that the system complied with the DPA providing the system was deployed within a secure internal network. This would most likely be the case within most large organisations. Extra functionality would need to be added in the long term to delete queries after a certain period to comply fully with the DPA.
