Now that Sprint 1 has come to an end, it is time for the retrospective blog. I will start by including everything I contributed to this sprint:

• https://gitlab.com/LibreFoodPantry/modules/visitmodule-tp/registerguest/Plan/issues/25#note_284824391

This link is a note in an issue where I have put a document discussing the Pros and Cons of whether we should be using a relational database or not. I put some examples of relational databases and non-relational databases for when I was making a decision along with links explaining a few of them.

• https://gitlab.com/LibreFoodPantry/modules/visitmodule-tp/registerguest/Plan/issues/35#note_296685089

This link is another comment on GitLab basically stating that we are using mySQL because of the simplicity and it is easy to look up information on it if needed.

• https://gitlab.com/LibreFoodPantry/modules/visitmodule-tp/registerguest/register-guest-data-base/-/tree/test-database

This is the repository for our database currently, it is currently on a separate branch and not merged with the master due to a sudden change in database fields which will be implemented first thing in the next sprint.

• https://gitlab.com/LibreFoodPantry/modules/visitmodule-tp/registerguest/tourofheroestutorial

This is another repository that holds the results of completing the Tour of Heroes Angular tutorial. This was the last thing completed for the current sprint to give me a refresher on Angular as I haven’t worked with Angular in a little over a year.

This was our first sprint so everything obviously wasn’t going to be perfect. However, I believe that we used GitLab very well considering this is my first time actually collaborating on a big project using GitLab. I think that we created issues that were specific enough to be considered issues. We utilized the boards well too. Our communication was mainly done through class and text message, but overall, I still think we communicated every issue that needed to be communicated.

Of course there were things that didn’t work well either considering it was the first sprint and this is most of our first experiences with Agile and sprints. While I mentioned that our GitLab use was very good. There were some faults with it as well. For example, my desktop didn’t let me push to GitLab which is an issue that still needs to be resolved. I specifically had trouble working with the separate branches because it was confusing at first. Our issues weren’t created the right way at first, and had to be restarted even though there were ways to just edit them without restarting. We had good communication, but I felt as though I wasn’t as involved as I should have been with the other team members work. I also think that there wasn’t enough communication between the other groups in the class as a whole.

Some of the changes that can be made as a team is more involvement in each others work. I think that we can all spend more class time looking at each others work rather than looking at it on our own time because this allows for more discussion. I also think that our team could start communicating with other teams more. Most of the teams came to us rather than us going over to the other teams to collaborate.

My individual changes that I need to make is talking more to my team members about what they have been working on rather than focusing on my own work. I could offer more solutions to the front end team about design. Probably my biggest issue would be my procrastination. I have to start working on my assignments earlier because that has an effect on how the rest of my team performs. I think that this next sprint will be much better now that we have been exposed to this more.

I think that the first sprint went well overall. My teammates and I completed all of the issues we assigned ourselves during the planning meeting, so the sprint was definitely a success. We accomplished this thanks to our effective use of the GitLab issue board. For the most part, our issues were clearly defined by their titles and labels, which helped us understand what needed to be done. Additionally, we assigned different team members to different issues, which made it easy to track our own issues and the progress of each other. The issue board also helped guide our in-class discussions, as the column-based structure allowed us to quickly select doing issues to discuss their progress and evaluate the needs review issues as a group before moving them to done. Finally, the board gave us a platform for discussion outside of class with each other and with other teams. We successfully used this to clarify what we needed from other teams and to answer questions among ourselves.

I think the main issue among the team during this sprint was communication. We did not always keep each other informed about our individual tasks, which sometimes made it difficult to resolve problems. During our class sessions, discussions frequently came to a stop after we reviewed our issues, leading us to silently work separately instead of collaborating. One major hinderance to our progress was an issue with our .gitignore file in the UpdateGuestWebUI repository. We had a branch where a mock Angular app was created, which had commits made before we finalized the .gitignore on the master branch. This caused unnecessary files to be committed, and we spent multiple weeks trying to find a way to remove them. We eventually found a simple solution that involved removing and recommitting every file after updating the .gitingore. It really shouldn’t have taken us that long to find such a simple solution, and I think we could have solved the problem quickly if we all worked together on it rather than focusing on our assigned issues independently.

I think there are several changes that can be made for future sprints, both for me individually and for the team as a whole. For myself, I think I could leave more comments on issues. I often made progress on my assigned issues or wanted to ask questions to my teammates, but I decided to wait until our class meetings to inform them about my progress and ask them my questions. Not only did this result in several of my contributions being undocumented on GitLab, but I also felt that it slowed the pace at which I could work. I also think that I need to work on communicating with the team in class more. During our meetings, I need to try listening better and making more contributions during discussions so that I can keep myself informed about the team’s progress and help my teammates resolve their problems more efficiently.

For the team as a whole, I think we can make some improvements to our usage of the GitLab issue board. I think we used it effectively overall, but there were some problems that caused confusion, such as an issue getting duplicated. We also exclusively used template descriptions for our issues, which sometimes made it unclear what we planned to do. I think we could better coordinate how we create and label our issues to avoid such confusion in the future. Additionally, I think the team could make improvements to communication. Instead of simply sitting in silence during class, we could explain to each other what we are working on in order to keep each other informed. Also, asking questions about issues and listening closely to comments from each other would undoubtedly help us avoid drawing problems out for too long. While this sprint was certainly an overall success, making these changes would help us work more efficiently and ultimately complete more of the project.

Things that worked well was letting people work at their own paces and at their own times in order to maximize work done. This laid back style that we used helped the members to not stress on what was done or what needed to be done by a certain time and allowed us to focus on the tasks at hand. Our team was very focused on each task and for the most part knew what we could accomplish. things that didn’t work were people calling different issues before they finished the one that they were working on which left other members trying to figure out what more they could do to be useful to the team. All of our reviews were done at the end of the sprint which made the quality of those review less than what they would normally be.
Since it was our first sprint, we were unsure of how much work was enough work and had a lot of free time to work on other issues because we finished the others early. As a team we could do reviews on Tuesdays and Thursdays to lessen the reviews needed at the end and allow for more time and consideration when reviewing each issue. We also need to only take one issue at a time and avoid planning out the work course for our whole sprint and instead only pick up the next issue when we finish the one we are working on. We should also set up schedule days to meet up and work together outside of class to be able to finish more and help one another with issues and problems that we might be facing. I want to work on making more time outside of classes to work on the sprint issues and work on more difficult tasks but since this sprint was just a set up sprint, I’m sure that I will be faced with more difficult/time consuming tasks. I also want to make sure that I add/write my ideas/communicate on gitlab so that it appears and if someone continues this project in the future they can understand my thought process.

What we did as group for sprint

Our first sprint we planned out what are the things we need to work on during the sprint and how long would it take. We assigned each other to what their tasks will be, whoever was comfortable in doing took the tasks and started working on it and whoever was unaware or was not sure everyone in the group made sure that the member has enough info to cover the task. 

After agreeing and planning out the sprint, we all started to work on the project. We started by creating two black angular apps for is register and register guest and one black rest server. We created classes and used java language for the rest API, HTML and TypeScript for Angular App.

One of the challenges that we faced during this sprint was working on the database. We decided to choose MySQL for our database.

Overview of what we did:

• Designing: endpoints, front ends
• Choosing the database program to run the server to match with Angular App
• Designing wireframes
• Coding backend
• Coding frontend

What i did for sprint

I volunteered to do the front end for the isRegistered. Shams and I discussed  what the layout of the page should look like. Before starting the code I made sure that the other team members agreed on the layout and language that I thought of using. To keep it simple, I used HTML and CSS and webstorm as the tool to write the code for the frontend.

What caught my attention was the Docker. I researched more on the docker whiel working on the frontend. I’ve never worked with a docker before and was curious in know how it works. I researched and shred whichever information I found helpful in understanding the  docker to the team.

Reflection on what worked well?

What worked well was frontend. I enjoyed my time coding and exploring more in designing the layout. It came out quite nice.

Reflection on what didn’t work well?

What didn’t work well for me was being consistent with the issues that were assigned. It was helpful in knowing the issues and working on it. But I rarely did a few because of figuring and working on the frontend. I would be aware of the next sprint.

Reflection on what changes could be made to improve as a team?

I feel like not everyone was on the same boat. There should be roles assigned, such as who is the manager, which keeps everyone on check. I do feel confused about what else we would be doing in the project. I recommend planning out and having everyone on check.

Reflection on what changes could be made to improve as an individual?

     More material the better the understanding of the task. I should research and discuss what/how my team members are doing. Knowing it would also enhance my knowledge on the project and I might be able to help them as well.

For the first sprint we did a lot of setup tasks as well as the designing of the architecture. In addition to some of the programming. The first thing we did was talk about the architectural design of the service. Once that was settled a group member created the wireframe for the “register” user interface. A group member also created the wireframe for the “is registered” user interface. The next thing we did was create the blank projects on gitlab. After this we initialized two blank angular apps in the user interface projects. We also created the blank rest server. While this one going on a group member was working the database understanding it and creating one that the architectural design specified. At the same time we created the class the design specified in the rest api and created the endpoints. We also connected the endpoints to a run-time database to test the rest server. In Addition we put in a template to learn how to make scheduled calls in a rest server. At the same time we also started coding the wireframe designs in HTML pages. That basically all we did for the sprint.

For the sprint I personally first created the main documentation issue and kept  it updated. I did this after the meetings or after consulting with the rest of the team and coming to a consensus with them. I also did several of the issues. First I did the issues for creating the 4 projects and initializing them. I also did the issue for designing the endpoints. I also did the issue for creating the object classes for the rest server. In addition i did the issues for creating the endpoints and finishing the rest server with a fakes database implementation. The last issue I did was researching how to make a scheduled method call in a rest server.

I thought the sprint went mostly well. I thought we did using the issue to break the work of the project up into smaller pieces for us to do. I also thought we did a good job of assigning issues to different people to make sure everyone had something to do. Lastly, I thought the documation issue worked well to keep the whole team on the same page as far as what the current plan was.

    Even though the sprint went well there were still some things we needed to improve on. I feel like there should have been more time spent planning before we started. Since a lot of  the first half of the sprint was spent changing our mind on the design and having to start over and this was inefficient. In addition before the working documentation issue was made we were not really telling each other what the plan was or when we changed it. We also could have had better communication overall especially at the start. We got much better later on though.

There are a few we could do better for the next sprint. I don’t think there is much however as we fixed most of the problems by the end of this sprint. The most important thing is to have a better planning meeting. We could be more communicative with each other on what we are doing. Lastly i guess the communication we do have could be better quality and more informative.

I could do a better job individually too. For the next sprint I need to do a better job of explaining why I am making the decisions i am making. I could also do a better job keeping the team updated on what I am doing and my progress. Lastly I could do a better job with the overall documentation of my issues. That being said, I don’t think me or anyone else in the team really needs to be better individually to much.  I think the biggest problem was the poor planning meeting at the beginning.

Here I am finding out about docker, posted resources to videos for the team.

These are the endpoints that I reviewed and moved to done.

From the very beginning of the spring we had assigned everyone an issue of what they needed to start on. From there each respective person worked individually on their assigned task until moving onto the next one. This was working well for our team in the beginning and for me, because I had a higher weight task, because everyone had something to work on. However, once I thought I was done researching docker and creating the wiki for the docker commands, I had run short of things to do with docker. My main task was familiarizing myself with docker but since we were not going to be using docker until at least the next sprint, there was little to do with everything I had just learned.

Another tough issue was the actual design of our endpoints. Our teams had not yet gotten the documentation of what would be stored for information on each person. For our initial design we made simple variables that could be replaced once the correct information was present. Eventually we were able to change into the correct variables with proper documentation.

Our team was very good at coordinating with the others when it came to work on our endpoints. We had originally designed them each with base variables as described before. After the documentation was given, the main problem that arose was the communication between other teams. We needed to understand what we were pulling from other teams and what they would be pulling from us. Our team did well to communicate and document the interaction and solutions on GitLab.

I think something that our team could do better in the division of tasks. For next sprint, as mentioned in class, we will be waiting to assign the next task once someone has completed theirs. I believe this will allow for a smoother distribution of work. Another team improvement, we could have better documentation when working through GitLab. When different people were working on different task, it was easy for the work completed to be missed. It can also cause a lack of understanding through the team if there is not much to go off of.

An improvement I could make would to be to take on a greater responsibility. I need to communicate to my teammates that I need to take on more work than previously because I felt a lot of time was wasted. I have to be better at involving myself in the ongoing process of something new in order to immerse myself, even if it is just to help push someone to the end of their goal. Another change I will make going into the next spring will be better documentation. I posted a document in the wiki for reference, but should be in markdown on the page for everyone to see easily.

Last week our team concluded our first sprint working on the Approve Guest module for the LibreFoodPantry project. This project is part of my Software Development Capstone and has us working on an open source project using Agile principles and the Scrum framework for software development. While I think the project has been going well, there are definitely aspects of our workflow that can be refactored in order to increase our productivity.

What I Completed This Sprint:

• Mock Angular Front-end – Fully functional Angular web application created to get familiar with Angular development
• Front-end wiki – Notes I took about Angular web development to benefit the team
• Initialized Spring Boot in REST API – Set up the dependencies for our REST API

For this sprint I took the role of Scrum Master for my team of four. I felt like this would be a great way to put my knowledge of the Scrum framework into practice. While I tried to make sure I was available to the team to answer any questions about Scrum, I feel like I didn’t emphasize the importance of following the scrum framework as well as I could have. I facilitated the stand-ups at the beginning of each class period as well as planning and review meetings. Our team did a good job of explaining what they had done prior to the stand-up and what they were going to work on, but the stand-ups were never used to raise questions about logistics or talk about progress towards meeting our Sprint goal. I feel this is because much of the Sprint was used for getting adjusted to the slightly more structured workflow that we are working with. If I continue to be Scrum Master for our team I will make sure that we utilize class time to the fullest in order to have open discussion about what we need to complete and how we can deliver working software as fast as possible while doing only the minimal amount of work necessary.

I think its important that, as a group, we start to utilize GitLab and our issue board to a greater extant than we did this Sprint. In the beginning of the Sprint we were having trouble coming up with what issues to work on because we didn’t have much information about exactly what it was we are building. I feel like not only our team, but all teams were very concerned with granular aspects of the project such as, what attributes should we be storing in our databases and what style guidelines should our applications use. All of the information that was up in the air was making it difficult for us to feel like we can start developing since everything is subject to change, but it is important for us to remember the Agile principle, “Welcome changing requirements, even late in development. Agile processes harness change for the customer’s competitive advantage”. We should be building this expecting requirements to change, rather than feeling the need to wait until requirements are finalized to start working. Also, I feel like even though our communication with each other and the other teams improved greatly from the start of the Sprint, we should be communicating as much as possible in order to maximize our productivity. We had good discussion with other teams but left minimal evidence of this on GitLab, which is something that we will need to be more vigilant about in the future.

We were able to finish all issues in the Sprint before the end, which is a sign that we gave ourselves too little to work on. I think as a team we made an acceptable amount of progress this Sprint as it was our first ever sprint working as a team. Going forward we can more accurately gauge how long each issue will take us to complete and make sure each member of the team delivers a reasonable amount of work by the end of the Sprint. Reflecting on what I delivered this Sprint I know for a fact that next Sprint I will need to give myself more issues to work on. I wanted to start working on our actual web applications, but the fact that our requirements were vague made me decide maybe we could leave that for the next sprint. I think my own fear of the unknown had me making many spike issues, when we could have made greater progress on the application itself.

Links below for my work on Sprint 1 of the LibreFoodPantry project.
MongoDB spike:
https://gitlab.com/LibreFoodPantry/modules/visitmodule-tp/checkout/Plan/issues/11
The goal of this task was to preview MongoDb and determine whether or not it will be useful for the project.

Production DB:
https://gitlab.com/LibreFoodPantry/modules/visitmodule-tp/checkout/Plan/issues/8
The goal of this task was to create a working Database to match our schema and work with our Rest API.

My favorite part of the scrum framework was actually the integration of kanban. The mixture of the two frameworks really made the work environment productive, predictable, and understandable. My team members and I assigned roles respectively to the scrum framework guidelines, at least two members of the team would know how something is done so that only one member would not have sole knowledge of the task. This way it made it easy to spread the knowledge throughout the team without holding up productivity. If one team member was busy then often the other would be available, or would be in the near future. This team plan also made development quicker in a way that if you were stuck on a task, your fellow task member may have another way of figuring out the issue. Together you can overcome obstacles easier than on your own. A great example of this is when I was developing a Production Database that could be used with our Rest API. I was having trouble figuring out the java code for MongoDb queries. Setting up the connection wasn’t the main goal of the task but it was necessary to have an understanding of it to be sure that MongoDb was the database application we would use. The issue was querying dates and one team member and myself were using CalenderDate which worked, but it ended up being eight lines of code to set up. My other team member on the task figured out LocalDate can achieve the same success with only two lines of code. If I had been left to the task myself the code would be less clean and bulkier, but thanks to my team members different approach we have clean and concise code.

The only things that didn’t work so well was our activity on planning and taking notes on Gitlab. We did not plan in the best way that we could have for the sprint and were constantly editing our backlog and to do lists. We also scarcely posted notes and updates on Gitlab. We did complete our task frameworks in order to move them into the done board. However, we did not thoroughly record our progress on Gitlab. In this way it could be hard for a newcomer to understand the evolution of our issues and how we solved them. They would only see the beginning and end product which is not clear and understandable.

To improve as a team we need to break down our planning technique and make sure our issues are concise and weighted correctly. I think our only problem with this was that we planned last minute because we were unclear of what was expected. However, now that we know we should be able to plan better and make sure our to-do list is concise.

To improve as an individual I need to record my progress, mistakes and achievements on Gitlab more often. Frequent updates on Gitlab would allow a newcomer to see my process and avoid failures that I may have already attempted so that they don’t waste time on something that already is proven to not work. Perhaps they actually solve a failure that I had attempted but was not able to make functional. Without notes to address these topics then a newcomer would not be able to interact and understand our work.
