(Yange et. al., 2020). The issue of rostering anaesthetist is challenging due to the multiple demands and requests
from the hospital and anaesthetists. Duty scheduling is the assignment of tasks to staff. It is the process of
analysing the workload in an organization, the time available to implement the workload and the distribution of
the work according to the time available (Yange et. al., 2020). This task is beyond the capability when the roster
maker needs to fulfil anaesthetist requests and always need to keep updating the roster.
Paschou et. al., (2015) proposed an intelligent mobile device application, to deal with lots of obstacles in
day-to-day medical rostering management and improved workflow in medical units. A few functions were
implemented to allow health care to get informed online and make ad-hoc changes to their shifts dynamically
through smartphone (Paschou et. al., 2015). Besides that, they implemented a calendar function to increase the
efficiency of the application in managing the roster. In other work, Zhu et. al., (2019) enhanced the existing
approach of manual staff roster planning by significantly reducing the number of man-hours used in the process
of planning and minimizing the possibility of human error in the rostering process.

3. Methodology

3.1. The Existing System

HCTM uses a manual system to generate a roster to schedule an anaesthetist. The monthly roster request is
prepared every month to collect the request for duty using Google Form. Anaesthetists can choose their duty on
preferred days and shift in that month. The roster maker will manage the roster by taking the data from the
Google Form and organize it inside Microsoft Excel.
The things that always requested by anaesthetist are:
 Leave
 Workshop/Conference
 Meeting
 Dissertation
 No Call
 AM Shift
 PM Shift
 Others

3.2. The Proposed System

The proposed system is a mobile application. This mobile application will help to collect the request from
the anaesthetist. The type of requests that are implemented in this application is a Roster Request, Emergency
Request and Swap Roster Request. Roster Request is used to collect monthly requests from anaesthetists before
the schedule is released. Therefore, the anaesthetist can plan their schedule wisely for that month. Sometimes,
anaesthetists will experience an unavoidable situation or problem that causes them unable to work that day or
time. Emergency Request can be a good platform for anaesthetists to request or inform the hospital about their
situations. This application allows anaesthetists to exchange duty with their colleagues through Swap Roster
Request. This function can give more flexibility to anaesthetist work at their preferred time and day.

3.3. Use Case Diagram
The use case diagram for the proposed system as shown in Fig. 1. depicts the interaction between the system
and the actors (anaesthetist and admin).
