Assignment 1:First Step in Building Modern Software
Paired assignment due: TBD(15%)
Overview
As discussed during the lectures, there are many technologies and tools you can use to build a
modern software product. In this assignment, you are asked to familiarize yourself with some of
the key tools you can use to build two of the most common types of software (web and mobile).
You can see this assignment as a preparation for your project or the first step in familiarizing
yourself with the modern software engineering world. You will work in teams of two to build a
tech stack, for a mobile or web application. The application you will be building is a simple
checkout price calculator with basic functions. You can think of the functionalities as that of
the system that is used during checkout. Use cases can be adding items, removing items,
applying discounts, adding tax, and any other realistic functionality you want to add but keep it
simple. (you don’t need any additional functionality, like save, load, advanced UI, etc.)
As you can see, the focus of this assignment is not on the complexity of the software but the
infrastructure you need to establish to be able to develop the software.
Assignment breakdown
This assignment has two major paths:
1. Web application: “How do we build a web application that can easily be developed,
tested, maintained, and deployed?” is the question leading this part of the assignment.
You will research various solutions and steps needed and build on top of what we have
talked about in the lectures. You can consider this web application would need (not part
of the assignment) some standard functionality such as login, search, post comments,
etc. and no special features (e.g., advanced visualizations, AI components, etc.). Your
application must be responsive.
2. Mobile application: “How do we build a mobile application that can easily be developed,
tested, maintained, and distributed?” is the question leading this path. You can make an
assumption about whether your application needs to run on Android, iOS, or both. But
you must clarify that assumption in your report.
The process you follow for each path is very similar. However, the end result will be different.
Please choose the path that you think your project will be in.
Next Steps
Your customer has chosen you as their trusted advisor and asked you to recommend a solution
for their needs. You can start your research from the roadmaps we have seen during the
lecture. Consider three main technologies to use for each part. For example, for the backend of
your web application, you can look at Node, Python, or Go, or any other language you find
interesting. For the frontend of your application, you can look at Vue, React, Angular, or any
other language/framework. You will then need to compare the options you have chosen.
Considerations can include (but should not be limited to):
1. Ease of development for you (e.g., you know Python but Go may be new to you)
2. Maturity of the language/technology and the libraries available for integrations/UI
3. The domains covered by the technology/language (e.g., Python also supports ML
projects while Javascript can do both frontend and backend).
4. Popularity of the language/technology. You can look at HackerRank 2020 Report,
Stackoverflow 2019 Survey, or JetBrains Developer Ecosystem report.
5. Performance, scale and speed of the solutions built with these technologies.
6. Any other criteria you think is important and needs to be considered
Your tech stack needs to include solutions for the following:
1. Frontend technology
2. Backend (web or mobile)
a. Needs to include Testing Infrastructure (e.g., PyUnit for Python unit testing). You
don’t need to have comprehensive tests. One test is enough.
3. Continuous Integration & Continuous Delivery (CI/CD)
4. Database (we will talk about databases in one of future lectures in more depth)
Your setup needs to support:
1. One development environment and a production environment.
2. Automated deployment on merge at least to the development environment.
a. You can use any of the CI/CD tools.
b. Your deployment needs to include running test(s)
Deployment
You are expected to make your applications available for your TA to see, test and grade (mobile
and web). You will need to “deploy” your applications. We will use the word deploy loosely here
meaning that you need to have your web application available via a url and find a way to share
your mobile app with the TA (e.g., apks, expo, developer account sharing, video recording, etc).
Expected Submission
You will submit three things in your GitHub repo.
1. A report containing the options you considered for your path (mobile and web). This
report needs to include at least three options and a comparison of pros and cons of each
of them. In the comparison, you can consider the following elements:
2. Your final solution that you decided to choose and the key reasons for that decision.
3. Please provide a summary of your analysis (Max 1000 words. This doesn’t mean you
have to write 1000 words. Quality is more important than quantity).
4. Application with all the details and instructions needed for your TA to see and test your
application. Please note that if your instructions are not clear enough to be easily tested,
you will lose 5%.
How to Submit
You will be submitting your assignment on Github. The following instructions will allow you to
form a pair and create a repository for submission:
1. You must form an assignment pair on Quercus by navigating to the ‘People’ tab, then
‘Assignment 1 Pairs’. Add yourselves to a pair (e.g., Assignment 1 Pair 1). The number
that you choose will be your pair number for this assignment
2. You must either create a repository using the following link or join an existing repository
that your partner has created. You will use this repository to submit all material related to
your assignment. Note that ‘assignment1-pair’ is automatically included in your Github
team name. In other words, only enter <pair-number>-<member1-github-id>-
<member2-github-id>.
Marking Scheme
Report (40%): Your report needs to contain the tools and languages you researched and
provide a detailed comparison of them leading to your final choice.
Deployed application (40%): You need to have deployed your application and setup CI for your
applications
Easily available and testable application (20%)
Evaluation
Your assignment will be evaluated according to the following rubric
Application Component Mark Weight Notes
Web/Mobile
Application
Report __ /400 40% 100 points per comparison
Deployed Application __ /400 40% 100 points per criteria
Testing Availability __ /200 20% 100 points per criteria
We will compute your mark by assigning each question a percentage according to the standards
set below and take the weighted average. Each point is really a percentage point (i.e. 85 points
on a question is 85% with regards to the standard below.
Evaluation Criteria for Report (Web / Mobile)
You will be comparing three main technologies for each of your four web application
components or each of your four mobile application components. Each of you comparison will
be evaluated according to the evaluation criteria outlined below:
Grade Grade Expectations
100%
(Outstanding)
– above expectations in quality or creativity of work (e.g. critical
thinking, creative approach, etc.) when performing comparisons
between technologies
– More than five considerations included in answer
– meets expectations for 80%
80%
(Good)
– answer meets all expectations and addresses all five considerations
listed in the assignment
– answer has both content and justification (i.e. what/how and why)
70%
(OK)
– some expectations were not fully met within the question either
because the answer is unclear or no clear justification was provided
for the comparison (e.g. you mention what but not why)
– one major (or a relatively small number of minor) point(s) were not
addressed in the question (i.e you did not talk about the domains
covered by the technologies)
60%
(Below
Expectations)
– more than one major consideration was missed or not addressed
within the answer to the question
– Multiple minor points are lacking clarity or clear justification
50%

too high-level (i.e. an answer was provided but met no expectations
or was not justified)
