Task details
What you need to do: 1. Read the Criterion-Referenced Assessment Rubric at the end of this document.
2. Read Case 1 (below) which pertains to all elements of this assignment.
3. Develop and document a list of questions for two of the key stakeholders to specifically gather functional requirements. Aim for approximately 10 key questions for each stakeholder type (you can also choose to add follow-up sub-questions if necessary).
4. Try out your questions on the Grower, Customer and Business chatbots (available from the end of Week 1) on Slack by entering a conversation with each under the “Apps” dropdown in the IFN552 Systems Analysis and Design S222 Slack channel. Note the chatbots are there to provide you with an opportunity to practice asking stakeholder questions and to provide additional ‘bonus’ information about the case; they will not be able to answer all of
your questions, but can help you explore and brainstorm some of the needs for the stakeholders. Please do not rely solely on these to develop your list of requirements.
5. Develop a Requirements Matrix to show the functional requirements of the new system. Aim for:
a) 15 Essential Functional Requirements
b) 5 Desirable Functional Requirements
c) 1 Optional Functional Requirement
You should include the suggested number for each priority of requirements, totalling around 21 Functional Requirements in your matrix. A small amount less or more may be ok depending on the quality of the ones you include, but you will need to stay around the number stated above. Whilst each will have certain priority, and the list may not be comprehensive, you need to ensure that all are relevant to the case and are concise, specific, measurable and actionable.
6. In 250 words or less, justify your choices (i.e. How/why did you decide to split the system into the modules you chose? How did you decide on priorities? Is there a particularly novel or unusual requirement that you have identified – if so, how does it meet the needs of your stakeholders? etc.).
7. Draw 1 (one) Use Case Diagram representing the new integrated system described in the case.
a) Aim to include around 15-20 Use Cases in your diagram (no more than 23). Ensure that the use cases you do include are important and relevant to the process being represented.
8. In 250 words or less also introduce your use case diagram (i.e.
what is it describing? At which points do users interface with the system? What is outside the scope of your diagram? Etc.).
9. Draw an Activity Diagram, representing how a grower would order a kit on the website, monitor the growth of their produce, organize a swap for their grown produce with replenishment seeds/cuttings and a customer eventually ordering some of that produce via the website.
You can start with the following assumptions:
a) Assume that the grower and customer are already in logged in states at the beginning of their processes (i.e., no need to include activities involved in login/register)
b) The delivery process is handled by an external company. There is therefore no need to include any activities associated with the delivery process other than those that involve the system being designed and/or other actors in the process
Remember to balance detail with clarity in your diagram. Take note of the following guidelines regarding scope:
a) Use around 2-3 swimlanes to differentiate system activities initiated by different actors. For activities performed by a subsystem with no interaction with an actor, you may use a separate “system” swimlane, however, ensure all other activities performed in actor swimlanes describe system interactions.
b) Use up to 60 shapes – ideally around 50 shapes – (shapes include boxes, decision nodes, fork and join, arrows, etc.) to show the process of user activities.
c) Use decision nodes two or three times and fork and join two or three times in your model.
d) Preferably, your activity diagram will be vertical, rather than horizontal (this will make it easier when merging it into the submission PDF).
10. Write a short description of your Activity Diagram in 250 words or less. Imagine you are presenting it to a set of stakeholders and you need to introduce concisely what it is showing (~1-2 sentences) and mention a few interesting/important activities or flows, as well as parts where you have made assumptions (~3-4 sentences). Note that it’s important to practice this skill, as you will
need to contextualise designs/diagrams when you create reports/presentations.
11. Save your submission and cover page as a single PDF
Presentation requirements: This assessment task must be formatted in the following way:
• 12 point font
• All diagrams large enough to be legible

Assignment 1 Case – Micro Farming Start-up
Company Case Study: BoxUp Micro
A fictional company using micro-farming to create a sustainable produce industry in urban areas.
Background: Your client is a micro-farming start-up that aims to bring farming to urban areas through the power of the crowd. They send out “Grow Kits” to individuals and small businesses to set up in small areas like backyards and balconies, the produce of which, they plan to collect and sell in an online store. “Growers” buy a kit from the company, set the system up and grow the produce. When produce is ready, growers will then box the produce up and book an exchange, where a delivery person will come to swap the produce box with a new set of seeds/cuttings. Once produce is received and checked, the company will pay the growers based on a predetermined price per weight of usable produce.
Problem: The business is in a period of growth, and wishes to streamline some of the complexities around the collection of small amounts of produce from individuals (as opposed to the simpler process of large scale supply traditionally done in the rest of the fresh produce industry). To do this, they plan to introduce sensors into existing and new Grow Kits that will collect data on the growth of produce plants which will feed into a forecast of inventory for the online store.
In addition, they also need to integrate an account management section for Growers on the existing website, which currently only acts as an online store.
It is your task to determine requirements and start the process of designing the new integrated system through a range of system design and analysis techniques.
ADDITIONAL INFORMATION
Sensors: Sensors in each kit will collect plant-growth data (e.g., CO2, moisture, root growth, etc.), which will be sent to a central database and displayed via a web application to Growers.
Grow kits: Grow kits contain a variety of seeds & cuttings of in-season produce like vegetables, fruits and herbs. Starter kits also include flat-packed growth containers, dehydrated soil & nutrient packs, as well as the sensors. When someone signs up to be a Grower, they can select from various sizes of grow kits (e.g., small, medium, large), which will be delivered to them so they can start growing.
Produce collection and Replenishment: Kits are replenished with new seeds/cuttings when the previous set is fully grown and ready to be harvested. Sensor data enables an algorithm to detect produce harvest time, which will prompt a notification sent from the system to the Grower, with a range of options to set pickup/delivery times. Kit replenishment is done at the same time as fully grown produce is collected: a delivery driver is booked, who brings replenishment seeds/cuttings and collects the box of produce grown and harvested by the Grower. The Grower can opt to meet the driver, or simply leave the box of produce at their doorstep for the delivery driver to swap the seeds/cuttings for. Seeds/cuttings sent depend on the season (i.e., winter, spring, summer, autumn).
Online store: The online produce store is a simple store where customers can select boxes of mixed produce of varying sizes. These boxes will generally be different from the individual boxes of produce sent to the company by Growers, as they will include a smaller set of more diverse fruits/vegetables and herbs put together by the Produce Managers at BoxUp Micro’s warehouse.
The boxes are currently set up as “lucky dips”, where customers will not know exactly what each box has, however, recent market testing has indicated that customers would prefer to know exactly what they are getting in order to plan their meals. There is therefore a need to integrate the sensor data from Grow Kits into the system in order to better forecast the inventory of produce available to each of the Online Store produce boxes.
Integrated system: With the upgrade of the Grow Kits to include sensors that transmit data to a centralised database, an algorithm has been added which can forecast when certain produce will be available and in what numbers. This algorithm is called GrowPredict. The business would like to use GrowPredict to help connect the currently separate systems of the online store and the Grower portal (which handles Grow Kit replenishment and produce collection).
Ideally, by integrating these into one system, the forecast provided by the algorithm will feed into the stock levels of produce shown on the website. Conversely, the purchase data from the online store will help determine the types and numbers of seeds/cuttings sent out to Growers in replenishment kits.
Stakeholders: Business owners & staff, customers of the online store, and the “Growers”.
The above provides a general overview of what is required of the new system. You will need to combine brainstorming with some limited interviewing (via three chatbots provided on Slack) in order to determine what is required for the new system.
As there are no set requirements that we are looking for, you have the opportunity to be proactive and creative, however, remember to make sure that the solution you provide matches the case (i.e. remember to keep referring back to the information provided in the above case description to avoid contradicting any of the details).

Academic Integrity
As a student of the QUT academic community, you are asked to work to uphold the principles of academic integrity during your course of study. QUT sets expectations and responsibilities of students, more specifically it states that students “adopt an ethical approach to academic work and assessment in accordance with this policy and the Student Code of Conduct. E/2.1 (MOPP C/5.3 Academic Integrity).
At university, students are expected to demonstrate their own understanding and thinking using the ideas provided by ‘others’ to support and inform their work, always making due acknowledgement to the source. While we encourage peer learning, it is not appropriate to share assignments with other students unless your assessment piece has been stated as being a group assignment. If you do share your assignment with another student, and they copy part of or all of your assignment for their submission, this is considered collusion and you may also be reported for academic misconduct. If you are unsure and need further information you can find this at: http://www.mopp.qut.edu.au/C/C_05_03.jsp#C_05_03.03.mdoc.
