Operating a Sandwich Stall using Agile Methodologies

Abstract
Agile has been adopted in the IT industry on a very large scale in the recent times. The Quick turnaround time and the Iterative and Incremental methods have done wonders in this Industry. But can this approach work in other industries. This study tries to answer this question where we have taken the Scrum and Kanban approach (SCRUMBAN) of Agile methodology to run a Sandwich stall which has been recently opened. The study follows all the Agile ceremonies and also has a Dedicated Product Owner, Scrum Master and the Development and Operations Team. This study runs for 4 sprints and proves that Agile and DevOps can be adopted in other Industries too successfully. With the Involvement of Stakeholders and Team on daily the product turnaround time is very significant and the Return on Investment (ROI) is very quick.
DevOps introduced us to world of having Cross-functional Team where each individual on the Team is capable of taking Additional responsibilities. The same is true about the paper here where every person working in the stall has to perform different set of duties on a weekly manner thus becoming trained cross functionally. Also Continuous Delivery has been made possible by using these methodologies. This paper attempts to bring 3 different methodologies Scrum, Kanban and DevOps and implement it in running a Sandwich stall to see the difference these methodologies can have in a Non - IT world.
Project Statement
The Stall owner wants to Increase his business Quarter by Quarter. Meanwhile he also wants to maintain the Quality and Introduce New flavours and New offerings over the Period of Time. He decides to use Scrumban as his business Methodology. Only 2 Sandwiches are going to be offered at the Opening. The Food Stall opens in Two weeks
WIP Limit – 3 for Product Backlog
WIP limit – 2 for Sauces
WIP Limit – 1 for new offering per Quarter
Sprints – 2 weeks
Team Size – 1 Product Owner, 1 Scrum Master, 6 Development Team
Work Break Down
Product Owner – Interacts with Customer and Collects Feed Back
Scrum Master – Makes Sure the Team is following Agile Methods
1 Development Team – Making Sure Everything is clean
1 Dev Team – Making Sure Veggies are there throughout the day

2 Dev Team – Handling the Non Vegetarian Counter
DevOps
• The Team uses the 5c’s methodology during the whole process

ConclusionFrom the above findings it can be safely concluded that Agile Methodology can play a very important role in the Food Industry. The approach of Scrumban is most suitable as one can place Work in Progress (WIP) limit and not rush out too many items in market which will confuse the Customer and will not be profitable to the Business. Following an iterative and Incremental approach and introducing new items to Customers gradually would work in favour of the Business. As one can look from an Investment perspective too in the above case study on can be in profit in very short amount of Time. Also by following all the Ceremonies related to Agile one can quickly resolve all the issues and be Just in Time for any new products.
51 story points were addressed over a period of 4 sprints leading to a profit of Rs 19321
I would like to conclude by saying “Agile is Hardwork but it does work”
