UML, short for Unified Modeling Language, is a standardized modeling language consisting of an integrated set of diagrams, developed to help system and software developers for specifying, visualizing, constructing, and documenting the artifacts of software systems, as well as for business modeling and other non-software systems. The UML represents a collection of best engineering practices that have proven successful in the modeling of large and complex systems. The UML is a very important part of developing object oriented software and the software development process. The UML uses mostly graphical notations to express the design of software projects.

2.Scrum

Here is a solid scrum definition when it comes to the scrum methodology. Scrum is a project management methodology which helps plan projects by breaking the scope of the project down into smaller groups of tasks to be done over short periods of time.

Scrum values​

Scrum values are work philosophies. When using a scrum system, you have a much more optimized approach to these ideas. The 5 key scrum values are:

1. Commitment

Commitments to deadlines, milestones and goals are crucial to running smooth project management. The scrum framework really helps with commitment by breaking things down into sprints of short durations, thereby avoiding the point where a team feels committed to something too distant, which is alienating and demotivating.

2. Bravery

Because of scrum’s system of having scrum roles like scrum master and product owner, there is enough leadership to inspire courage among the product developers and other team members. And even if with scrum you iterate more often, courage in your planning and tasks is always recommended.

3. Focus

When there is a lack of focus in project planning, resource allocation, and division of labor, it’s hard for every individual or team to be able to zoom in on their tasks at hand. Scrum highlights focus with laser precision for everyone with sprint planning, while sprint retrospectives can help refocus for the next round of tasks.

4. Honesty

The daily standup meeting or the daily scrum meeting is a fantastic space for scrum team members within and between departments to get together and be open. Great topics are the obstacles one foresees or what one department might require of another if, for example, some parts of the project have to adhere to a waterfall system.

5. Respect

Respect is the lifeblood of all team collaboration and communication. How does the scrum principle of respect apply in everyday project planning? When people feel seen, heard and respected, they’ll be more ready to participate in planning sessions, or to voice their opinions if they spot something is off, thereby saving the project on time and expenses.

Scrum principles​

And now, here are the core 6 scrum principles. They tell you how to approach your job so that everyone using the scrum system benefits.

1. Control

Having control over the empirical process is the first big scrum principle. You have to take a good look at the resources you have or have access to, for example. Do regular inspections, and also be transparent with what you find out. What’s more, be realistic if you feel you need to adapt. People in all scrum roles benefit when this principle is respected.

2. Organize

Organization is the next principle of scrum. Although projects are always a teamwork effort, scrum optimizes for much self organization. This is great for allowing individuals and small scrum teams to figure out for themselves how best to reach each sprint goal, deliverable or product increment milestone.

3. Collaborate

Team collaboration and interdepartmental collaboration is an important scrum principle. Although scrum allows for the self-organization of independent work, it also provides good collaboration when it’s needed. When team members are aware of one another and they feel comfortable communicating, scrum functions more smoothly.

4. Prioritize

In order to get the most out of your scrum methodology, pay heed to the scrum principle of value-based prioritization. Things to think about when planning your projects are which tasks are the most important or most difficult or time consuming or costly, and combine those factors to set priorities. But also always be prepared to shift priorities if the need arises, as it often does in business.

5. Timebox

Timeboxing is another way of talking about sprints, because you are creating time-boxes that are contained and small enough to handle without much difficulty. In most cases, the time-box for a sprint is a fortnight. The scrum meeting is a hyper example of the time-box, as it is usually set at no longer than 15 minutes a day. Timeboxing is usually taken care of by the scrum master.

6. Iterate

Iterative development is all about not putting the cart before the horse. When your team envisages a new product, it’s a good idea to break it down into stages (like a waterfall) where you can regularly produce something worth testing and getting feedback from. This is often the purview of the product owner.

What is Agile Monitoring?​

The Agile methodology is a practice that encourages continuous development and testing throughout the software development lifecycle of a project. Unlike the Waterfall methodology, the Agile methodology allows for parallel development and testing.

Agile methodologies attempt to produce the proper product through small cross-functional self-organizing teams that produce small pieces of functionality on a regular basis, allowing for frequent customer input and course correction as needed. In doing so, Agile tries to address the issues that traditional "waterfall" methodologies of delivering huge products over extended periods of time encounter, such as client requirements changing frequently and resulting in the delivery of incorrect products.

Stages of Agile Monitoring​

Agile development is not that tough when broken down to its core concepts. While the number of meetings involved may appear unnecessary, it saves a lot of time by optimizing development tasks and avoiding the errors that can occur during the planning stages.

Phase 1: Requirements​

Before a Product Owner can begin creating a project, they must first generate the initial documentation, which includes a description of the project's needs. They are as follows:

  • The eventual result that the initiative will attain. For example, a text editor.
  • The functionality will provide. For example, different font sizes.
  • The features that it will not originally support. For example, adding text animations or the ability to embed video.

A general guideline is to reduce these initial needs as much as possible, adding just the elements that are absolutely necessary and discarding those that will not be used frequently. Developers can work on them once the application has been released and the core features have been tested.

Phase 2: Design​

In software development, there are two approaches to design: one is visual design, and the other is the app's architectural structure.

Software Design

The Product Owner gathers their development team and introduces the requirements developed during the previous stage during the first iteration. The team then explores how to approach these objectives and suggests the tools required to obtain the best outcome. The developers debate feature implementation and the internal structure of the come in subsequent iterations.

UI/UX Design

The designers build a rough mock-up of the user interface during this stage of the SDLC. When it comes to consumer products, the user interface and user experience are crucial. As a result, it's a good idea to look at potential competitors to evaluate what they're doing correctly — and, more importantly, what they're doing poorly.

The basic design is refined and/or reworked to accommodate the new features in subsequent iterations.

Phase 3. Development and Coding​

Within the software development process, the development phase includes producing code and translating design documentation into actual software. This is the most time-consuming stage of the SDLC because it forms the foundation of the entire process.

There aren't many differences between iterations in this case.

Phase 4: Integration and Testing​

During this stage, the developers ensure that the software is bug-free and compatible with everything else they've built previously. The Quality Assurance team runs a series of tests to check that the code is clean and that the solution's business goals are satisfied.

Testing grows more comprehensive as this SDLC stage progresses, and includes not only functional testing but also systems integration, interoperability, and user acceptance testing, among other things.

Phase 5. Implementation and Deployment​

The program is installed on the servers and made available to customers, either as a demonstration or for actual use. Iterations after that update the existing software, adding new features and fixing issues.

Phase 6: Review​

The Product Owner gathers the Development Team once more after all previous development phases have been completed to discuss the progress achieved toward meeting the requirements. The team presents their ideas for correcting the issues that developed during the previous phases, and the Product Owner considers their suggestions.

The Agile software development lifecycle phases then begin over, either with a new iteration or by progressing to the next stage and scaling Agile.
