POS MAINTENANCE PLAN
1.
Maintenance Team Building
To further maintain the Delicious Fast Foods POS platform, a team will need to be formed to
take care of parameters such as – i) Payment System and tracking finances
ii) Fast response time during rush periods
iii) Access management
iv) Ability to take orders and bill customers smoothly
v) Smooth integration with 3
rd
party delivery services such as GrubHub, UberEats etc.
For this we will require a system administrator to keep track of the system’s general health
and issues. We will require 2 testers to test and debug servers. 3 Software developers who
have played a part in building the platform can be useful in adding new features and also
performing general maintenance. Lastly, we will also have a systems analyst who
understands the system and can explain it to new hires.
2.
Software Maintenance
a.
The 2 testers will perform corrective maintenance where their job is to constantly debug
faulty codes and perform hardware checks.
b.
The system administrator will keep an overall check on the system noting down the
growth of the traffic on platform and also customer feedbacks to understand where the
platform is lacking. A preventive approach can be taken where the system admin will
request the software developers to upgrade the platform in order to handle increasing
traffic. This can provide the platform from crashing especially during peak periods.
Further, if any changes in the system are required, or if any additional feature needs to
be added, the system admin can direct the team in implementing them.
3.
Performance
a.
Response time is a key factor while building a platform. As it will be distributed, the
response time may be slow. It is very important to maintain a good response time to
have customer retention – A frustrated customer will often tend to get restless and
disappointed with a slow response time.
b.
The system administrator is also responsible for providing a forecast on the amount of
incoming traffic depending on the history of number of orders placed during rush hours.
This way the team can plan how much the system can handle and have adequate
capacity for the same.
4.
Security
a.
Access management needs to be implemented through the system to avoid data leaks
and provide more security. The root user should be the only one with access to all areas.
b.
Access should be provided to team leaders based on their respective domains. (i.e. –
Only a lead accountant can access payment history and transaction data unless there is a
specific need for external access).
c.
Further, Password strength for users should be 8 characters minimum, expires every 90
days and must contain both upper-case and lower-case letters.
5.
Backups
Incremental backups should be ideal for DFF’s platform as they will keep saving the updated
information of every new order, payment and transaction made from time to time
6.
Termination
a.
We will assume the total estimated cost of building and maintaining the platform to be
$300,000/year.
b.
Assuming that DFF receives 400 orders a day and a single order on an average cost $10,
the revenue generated will be $1,460,000/ year.
If 20% of the revenue goes to 3
rd
Party delivery services, DFF earns $1,168,000/ year
Profit = 1,168,000 – 300,000(Salary and platform maintenance) – 200,000 (for delivery
services, vehicles for transport and permits)
Profit = 6,68,000/year.
Thus, the platform lifecycle should be at least 4-5 years to earn reasonable profits (~10x).

Object Oriented Analysis
For using object-oriented analysis for maintenance process, we will require a class for every
category – Orders, Payment, System Maintenance, Accessibility, Platform maintenance.
These can have sub classes with dedicated staff members assigned to each of the class. The
work can be performed simultaneously where the staff specializes in their domain instead of
having them work through the platform on every domain.
