Difference between Scrum and Waterfall Methodologies

By Ada Jacques-Leahy

March 13, 2022

Hello World! I am here on this fine spring morning to delineate the difference between Scrum Methodology with an Agile mindset (Agile is not a framework/methodology) and the Waterfall Methodology. After much research I have deduced that the main differences are many. The main difference between the Waterfall Methodology and Scrum is that the Waterfall Methodology has two set rules. One is that the Waterfall Methodology is for small projects. The second is that it has very distinct phases in which one must finish before the other can start. I personally believe that this methodology should get renamed to something like “Brick and Mortar Methodology” because you need one brick as a foundation before you can set the next brick. Waterfalls are fluid and not rigid in this methodology, no pun indented.

The Waterfall Methodology is the traditional method from the 1950’sof doing things whereas Agile in Scrum Framework is a newer approach where the customer is (as it should be if need be) closer to the center of it all. The Scrum method is also more lenient with less rules (structure).

With the Waterfall Method, you have: poor amount of customer input, documentation, a strict hierarchy and Sequence Principles at the forefront; whereas, with the Scrum Method the workflow works more Agile-like and seems to be more relaxed. With the Waterfall Method, if you fail in one area, you cannot go back and fix it; you have to start from scratch (which is senseless and ineffective in my opinion).  As in the cybersecurity world where you prepare for the big hack all day long/every day, documentation is essential just like in the Waterfall Method. The basic steps in the Waterfall Method’s project are: planning, designing, performing, testing, and the final deployment. 

The Scrum Method, developed in 1993, has more of a King Arthur’s Round Table approach where there is not only one Boss (like in the Waterfall Method) but rather many people contribute and have equal say and vote as how to approach the project, which is a more modern type of democratic rule (Scrum) versus a monarchy type of rule (Waterfall). The Scrum Method calls for a Coach (Mentor) and no Boss. The Scrum method calls for stages called Sprints stopping somewhere in the middle to have the Product Owner (Customer Rep) evaluate it. Flexibility throughout the project exists to change the final outcome unlike the Waterfall Method. Scrum is also sometimes referred to simply as the iterative work cycle of Sprints that last about two weeks on average, but can last from one to four weeks as well.

In conclusion, both methodologies should get you to the same place at the end. Depending on your project(s) needs and the team players employed in your team, you can choose either methodologies to best suit you, and your organization’s needs tailored to a specific project.

When you visit Facebook’s Yosemite’s National Park by clicking on one of the buttons below you will see that you can use the page to know how to get to Yosemite. It gives you a most current News-feed on current events happening on Yosemite, and Covid alerts. You can also gauge the park’s popularity by taking note of how many followers the page has.

The best part of the page is that you can see beautiful photos of the park. If you need to go to their official page you can also do that from here as well. You can “Like” it and choose to follow it in your very own News-feed, if you want. You can see which of your Facebook contacts/friends/family members also like the page. This particular page also has videos on Yosemite National Park. You can find the park’s phone number on this page. This page is great! I don’t suggest any changes made to it. More vivid pictures and an announcement of no future events planned because of Covid would be nice but not needed, assuming that this is the case.

How to Keep Passwords Safe

Make your passwords contain a mixture of: upper case, lower case, symbols, and numbers. Spaces are not allowed in passwords; don’t use your birthday or common knowledge information about you as passwords. Use a password manager that you trust and share your password(s) with one trusted person in case something happens to you and you can’t access it yourself. If you are using AWS, erase your root login credentials once your account(s) are set up, set yourself up as a user in the IAM management console. Keep your root user credentials somewhere else safe before you erase your root user ID login credentials from the computer. Don’t give your passwords to anyone unless it’s in a website that you trust, has https in their URL and the lock pad symbol in the URL.

A Good Password Manager

There are many good password managers recommended by IT Professionals as published in Jean Andrews’ CompTIA A+ Guide to IT Technical Support out there; like: Dashlene, Sticky Password, LastPass, and KeePass. I would go with LastPass because you can try it for free and it’s recommended by IT Professionals as well. The free version is not recommended by the site below because the syncing feature is not very good but when you are on a budget it might have to do. It’s also somewhat out of date. It’s good for many browsers and platforms. It reports to you telling you how strong your password is. It also has tools to help you monitor the dark web and has a Multi Factor Authorization (MFA) technique to help your password be more secure by practicing the something you have and the something that you know policy.

ETHICS IN TECH

This has been one of my favorite subjects to write about because it’s such a new emerging field that in many ways, it’s such a brand spanking new field of study that not much has been decided as a consensus onto what it right and what is not right. We live in an age where we had a POTUS that caused riots through spurring social media posts, and another recent POTUS ingress that has, for the first time in history, created a long overdue “Office of Science and Technology Policy” office.

After looking up Humane Tech Organization on Wikipedia (since their website’s agenda is quite obfuscatory and murky, at best), I take the stand that social media is definitely responsible for the fake news, and misinformation that it perpetuates. I don’t think that social media is responsible for the political chaos that social media became after Trumps’ POTUS term began like the Humane Tech Organization implies. I believe that it’s human nature to obsess with political: memes, posts, shares, etc. I do believe that that it’s their responsibility (social media) to make sure that things go smoothly without infringing on an individual’s free speech and freedom of the press rights. They are the leaders in this responsibility because of the simple fact that they are the only ones that have the power, and moral high ground, to monitor what happens on their sites. They are the ones with the security clearance in their companies (and the technical know-how) that can make that happen. It is a very difficult to stand by freedom of the press, and free speech as well as monitor for the truth and misinformation in a social media platforms at the same time; but, it has to get done. If you are willing to make your own social media platform, I would suggest you to hire a powerful team of fact checkers to make sure that you don’t get sued from what gets posted on your platform.

There has been only a handful of movies/mini series based purely on the tech industry, to this date, despite how much tech has served as an invaluable tool in the every day of a person’s daily life. One of those movies is The Social Dilemma that depicts the true life story of how Zuckermann (founder of Facebook) stole the idea from his college roommates and didn’t even take a grateful second look back. The courts finally set precedence by ruling that what Zuckermann did was perfectly legal because it was he who could proof that it was he who wrote the code (allegedly) to the social media giant platform that it is today. This serves as a lesson to all in the tech startup industry that unless you have a signed (and vetted from a corporate law/copyright lawyer) non disclosure agreement signed by all parties involved; DON’T SHARE YOUR IDEAS WITH NO ONE AND BE CAREFUL ON HOW YOU COPY AND PASTE NON OPEN SOURCE CODE!!!!!!!!!!!!!!!! YOU MIGHT BE BREAKING THE LAW! If you are unsure of what you can copy and paste freely, after making your necessary modifications first, contact the author(s) and get written, explicit permission to use their code.

I came to a stark realization that after talking extensively with tech giant (ex NSA Cyber Security Analyst), that invented the “text message and data rates may apply” phrase, about Snowden. He said that everything that Snowden said to the media is true. The government has absolutely no respect for the privacy of the individual citizen simply because laws have not been created to protect people’s: privacy, their data, their right to freely post yet, etc. Although search warrants should apply for digital findings as well; simply because, laws have not been made to protect an individual’s rights online, it simply doesn’t happen. I believe that every: Coder, Software Engineer, Data Scientist, IT Professional, Cyber Security Specialist, etc. has the ethical duty and responsibility to take people’s data with respect to the individual’s privacy and treated it and/or publish it responsibly.

We have come a long way from Halt and Catch Fire’s historical depiction of how open source code was deemed illegal in the past and still need a long way to go where people actually are held accountable for spreading viruses, hacking and proper data usage guidelines that are just and fair for all!
