Waterfall And Agile Model Workflows

In simple English, Agile means ‘able to move quickly and easily’ and hencethat is what it means when it comes to the Agile development methodology.Agile is a method of project management that is represented by splitting thetasks into shorter segments of work with frequent reviews and adaptation ofplans.Similarly, the word waterfall denotes a vertical flow of water or the flow ofwater through a series of steep drops. The waterfall model is a linearsequential model in which the progress flows majorly in one directiondownwards through the phases of requirement gathering, analysis, design,development, testing, deployment, and maintenance.This same illustration applies to the concept of project management when itcomes to the waterfall model. It is a method of project management that isrepresented by serial stages and a fixed plan of work.[image source]Before discussing the Waterfall workflow and Agile workflow, let us have alook into the Software Development Life Cycle definition and its requirements.

What Is The Software Development Life Cycle?

It is a step by step procedure to develop the software systematically. Forthis, we select from different types of software development life cycles indifferent companies. Based on the requirement, an appropriate life cycle isselected.The waterfall model is one of the SDLC types and it is an old process ofdeveloping software. The agile model is the latest and advanced one. Agile isderived from other software development life cycle.Other SDLC includes the spiral model, V and V model, Prototype model. Based onthe necessity and compatibility of the business requirement, we will choosethe best model to develop the software application.[image source]Why software development life cycle is required?SDLC is required to manage the project in a structured way. It provides acertain level of control and defines the roles and responsibilities of theteam members. It provides the scope and deadline for each phase in SDLC.It is somewhat like a user guide to the team members to follow all the stepsto develop and deliver the quality product. It helps the team management todefine and evaluate the objectives and requirements. It also helps inscheduling and estimating the tasks. It makes the communication line betweenthe client and the development team and creates the roles and responsibilitiesfor each of them.

Agile Workflow

Now we will see the Agile Software development life cycle. Agile is theprocess of doing work quickly and easily with more accuracy.This model is related to a method of project management, used especially forsoftware development. It is characterized by the division of tasks into shortphases of work and frequent reassessment and adaptation of plans. Each teammember should have the idea of the basic business flows.[image source]In Agile, developers and testers work parallelly to develop and test theapplication software. Development is done in iterative mode. Each iterationuser stories requires the analysis, design, coding, and testing.We test the requirement in a detailed manner to verify if the requirement iserror-free and implementable or not. Switch to next iteration after the end ofeach iteration and we follow the same process to the new/other requirements.Thus, this process of developing and testing the block of software isperformed in a short duration of time with more accuracy and flexibility. Somore industries follow and adopt this process.First, the product owner will add all requirements to the product backlog. Theproduct backlog contains all the user stories. Let us say, 100 to 150 userstories are related to the complete project. Now add the particular userstories to the sprint backlog which we need to be implemented. Then, all thedevelopers, QA, BA will work on the sprint items. This is how Agile flowworks.

The Top Five Software Project Risks

By Mike GriffithsRisk management (or more precisely risk avoidance) is a critical topic, butone that is often dull to read about and therefore neglected. One of the fewuseful and entertaining books on the subject is Waltzing with Bears: ManagingRisk on Software Projects by Tom Demarco, Timothy Lister, authors of the everpopular Peopleware. This post provides a useful summary of their top fivesoftware project risks.While not an agile focussed book, I find it interesting that of the top fivesoftware project risks identified in Waltzing with Bears, all have suggestedsolutions rooted in agile methods. Demarco and Lister rate the top five risksand their mitigation strategies as:

What is Agile project management?

Agile project management is an iterative approach to project management thatfocuses on breaking down large projects into more manageable tasks, which arecompleted in short iterations throughout the project life cycle. Teams thatadopt the Agile methodology are able to complete work faster, adapt tochanging project requirements, and optimize their workflow.As the name suggests, the Agile allows teams to be better equipped to quicklychange direction and focus. Software companies and marketing agencies areespecially aware of the tendency for changes from project stakeholders tohappen from week-to-week. The Agile methodology allows teams to re-evaluatethe work they are doing and adjust in given increments to make sure that asthe work and customer landscape changes, the focus also changes for the team.If you’re new to the Agile project management, it might look at first like acomplex and difficult-to-manage system. But, whether you realize it or not,you’re already doing many of the things Agile requires. With a few tweaks,you’ll be on your way to shorter development cycles and smaller, more frequentproduct releases.

Who uses Agile project management?

Originally created for software development, the Agile approach to projectmanagement is quickly being adapted by more than just IT teams. Marketers,universities, the military, and even the automotive industry are also lookingat the Agile methodology and other Agile frameworks to deliver innovativeproducts in uncertain environments. Many organizations can benefit from Agileproject management, and it’s simple to set up and utilize.In the software world, when a decision to build or further develop an existingtechnology is made, the end product may be hard to define. Agile allows forthat ambiguity because of its flexibility to change direction on a project aswork moves into the future.While you can take advantage of Agile software, books, or Agile coaches, eachAgile team is unique, and understanding the basics can help you put togetheran Agile methodology that works for you and your team.* * *Whitepaper: How to Become an Agile AgencyWhitepaper: Agile Marketing for Creative Teams* * *

2. Working software over comprehensive documentation

As important as documentation is, working software is more. This value is allabout giving the developers exactly what they need to get the job done,without overloading them.

Key components of Agile project management

Put simply, a user story is a high-level definition of a work request. Itcontains just enough information so the team can produce a reasonable estimateof the effort required to accomplish the request. This short, simpledescription is written from the user’s perspective and focuses on outliningwhat your client wants (their goals) and why.Sprints are a short iteration, usually between one to three weeks to complete,where teams work on tasks determined in the sprint planning meeting. As youmove forward, the idea is to continuously repeat these sprints until yourproduct is feature ready. Once the sprint is over, you review the product seewhat is and isn’t working, make adjustments, and begin another sprint toimprove the product or service.Daily stand-up meetings (under 10 minutes), also known as “daily Scrummeetings,” are a great way to ensure everyone is on track and informed. Thesedaily interactions are known as “stand up” because the participants arerequired to stay standing, helping to keep the meetings short and to thepoint.An Agile board helps your team track the progress of your project. This can bea whiteboard with sticky notes, a simple Kanban board, or a function withinyour project management software.

Transitioning to Agile project management

Once you feel comfortable moving forward with Agile, you’ll want to start byeducating your Agile teams on how they will transition into their new roles,when they will begin having daily stand-up meetings, and how they willtransition their current work into the Agile methodology.After you establish transition steps and make sure everyone is comfortablewith the new style of work, you’ll want to monitor and track their progressand success.If they are struggling to run at the same velocity as before, what may becausing those issues? If the team isn’t updating stories with their currentstatus, have those statuses been clearly defined?Tracking a new Agile team’s progress or success will be very beneficial togiving it confidence in the changes. In addition, having these Agile metricswill help justify the benefits of transitioning a team to Agile when inhigher-level meetings.Finally, it’s important to provide your team and new Scrum Masters with a formthat outlines helpful questions to ask during daily stand-ups and theiteration retrospectives. This provides some excellent documentation forfuture reviews of processes. It will also allow for the team to identify areasthat need improvement and help it answer questions it may not think to talkabout if it is new to Agile.* * *Learn more: Implementing Agile at scale* * *

Get started with Agile project management

These are the most basic and important parts of Agile project management. Asyou transition your team to an Agile methodology, these processes, Agilesoftware and tools, roles, and principles will help you change your mindsetand begin working together to be more flexible and adapt to changes as theycome. Agile isn’t for everyone, but teams who use it correctly will experienceenormous benefits, including streamlined work processes and rapid innovation.Agile Methodology – Software Development, Mainfesto, Best PracticesAgile Methodology is a type of project management process, mainly used forsoftware development, where demands and solutions evolve through thecollaborative effort of self-organizing and cross-functional teams and theircustomers.Stemming from the values and principles of the Agile Manifesto, it was createdas a response to the inadequacies of traditional development methods such asthe Waterfall method. The software industry is a highly competitive market dueto the fact that software is something that can be continuously upgraded. Thismeans that developers need to constantly improve and innovate their productsto keep on top of the game — and the linear, sequential approach of theWaterfall method just wasn’t cutting it.

Agile Software Development

In the 1990s, software development faced a bit of a crisis. Referred to as‘the application development crisis’ or ‘application delivery lag’, theindustry realized that it couldn’t move fast enough to meet customer demandsand requirements — the estimated time between a business need and actualapplication was about three years. See, traditional development models werebased on a timeline approach, where development happened sequentially and thefinal product wasn’t revealed to customers until the very final step. Thisleft little room for flexibility when it came to progress reviews and changes.So, by the time an actual application was finished, it was highly likely thatrequirements and systems of the project’s original objectives had changed.With money and efforts wasted and even some projects cancelled halfway throughprofessional leaders of the software community thought it was time for a new,refreshed approach. Then in 2001, in a snowy, ski lodge in Utah, gathered 13individuals. Some of whom were already entertaining the idea of a new softwaredevelopment method. They all yearned to cement a process that legitimized whatwas being practiced, and so, came the creation of the Agile Manifesto.
