In the previous blog article, we presented everything you need to know about software development methodologies. We showed you the phases of the software development process and discussed sample methodologies. As we know choosing the right methodology is not easy, we would like to discuss more of them to make it easier for you. 

DevOps methodology 

DevOps is a way to improve collaboration and tight integration. It is a way to automate the process between developers and IT teams. 

DevOps is a set of practices that combine software development, testing, and operation. 

Traditionally, the person who wrote the code has not collaborated with the person who implemented the code. Developers and operations specialists have different goals and work on different floors and even buildings. DevOps is so good because it brings two teams together. 

By collaborating between developers and operational experts, software can be tested faster and more reliably. 

The following categories are used to describe how any tool can help DevOps: 

  1. Plan 
  2. Code 
  3. Build 
  4. Test 
  5. Release 
  6. Deploy 
  7. Operate 
  8. Monitor 
DevOps methodology

Pros 

1. Faster implementation of new processes, systems and applications by companies. 

2. The team works closely together, so less chance of mistakes. 

3. More time to ensure quality and speed of delivery. 

4. Improve customer service, due to the prompt delivery of high-quality system. 

Cons 

1. Hiring skilled DevOps professionals with hands-on experience can be difficult. 

2. This method requires human intervention, which may slow down the delivery process. 

Lean Development 

If you want to develop software in 1/3 the time and are on a budget – take a look at Lean. Across all industries, lean models are used to lower development costs, improve quality, increase productivity and increase customer satisfaction. 

In short, lean Development is the application of Lean principles to programming. It has 7 main rules including: 

1. Pay attention to customer needs. Get rid of anything that does not add value to the customer. 

2. Use lean development tools (for example, pair-based and test-based programming) to improve quality. 

3. Create knowledge. Encourage your development team to properly record and store valuable knowledge. This can be done through code reviews, documentation, and knowledge sharing sessions. 

4. Collect information continuously, instead of making decisions without the necessary data. 

5. Deliver to customer ASAP. 

6. Respect your employees. Encourage them to communicate actively and effectively and give them a chance to do their best. 

7.Optimize your value stream to deliver the greatest value to your customers as soon as possible. 

Lean Development

Pros 

1. Eliminating waste as early as possible can speed up the development process and reduce costs. 

2. Delivering high-quality products on time can increase customer satisfaction. 

3. By involving your team in the decision-making process, you can motivate them to act. 

Cons 

1. Team dependent method. This means you need to create the perfect team with unique skills. 

2. Lean development requires detailed documentation. If any aspect of the development process is not fully documented, it could be underdevelopment. 

Dynamic System Development 

If you are frustrated by expensive, rigorous, and unreliable software development practices, you can take a look at the Dynamic System Development approach. 

The dynamic system development model methodology is derived from the rapid application development methodology. It was created when needed to improve the responsiveness of the project and deliver on time according to the budget. It is highly documentation reliant and has the best supported documentation of all agile development techniques. 

The model focuses on: 

– user involvement, 

– enabling the team to make decisions, 

– conducting integration tests throughout the development cycle, 

– cooperation between all interested parties, 

– reversible changes during development. 

Pros 

1. Developers have access to end users 

2. Detailed documentation is kept 

3. Projects are delivered on time and on budget. 

Cons 

1. The method is not suitable for small businesses 

2. Implementation is costly. 

Feature driven development 

If you are working with a larger team, it makes sense to adopt a functional programming approach. Its models can accelerate development and deliver on time. FDD is a combination of several industry recognized best practices that focus on customer value. 

New features are released gradually. In this way, developers can prioritize clients ‘requests and respond to clients’ requests in a timely manner. To keep customers satisfied, developers calculate what functions they can create. They then split the complex request into smaller feature sets and came up with plans for how to achieve each goal on time. 

Feature driven development

Pros 

1. Allows for faster development 

2. Compliant with the best practices recognized in the industry 

3. Larger teams can push the product forward and achieve repeatable success. 

Cons 

1. Not suitable for small projects 

2. Misunderstandings may arise due to less written documentation 

3. This method is highly dependent on the lead developers. 

Iterative software development 

Iterative software development cycles or sprints provide users with early value through frequent spending. The length of the iteration can be constant or variable. While the Agile Manifesto does not require iteration, the use of iteration is usually synonymous with agile. Then, the two best known iterative methods are discussed. Scrum and extreme programming (XP). 

Scrum 

Scrum is great. It belongs to the iterative category of software development methodology. Scrum uses Fixed-Length (Time-limited) Sprints, and each Sprint has a goal that the team is striving for. 

Scrum is based on three pillars: transparency, inspection and adaptation. It also has five values: commitment, courage, focus, openness and respect. Successful use of Scrum is when the team is proficient with the five values and the three pillars that support each implementation. 

Pros 

1.Possibility of applying changes to the project on an ongoing basis during its implementation 

2. Possibility to adjust the scope of the project on an ongoing basis and close it at any time 

3. Reduced paperwork and bureaucracy 

4. Faster and more effective project delivery 

Cons 

1.Lack of knowledge about the exact cost of project implementation 

2.Risk of project expansion 

3.The risk of exceeding the assumed budget. 

Extreme Programming (XP)

Extreme Programming (XP) 

XP uses fixed-length iteration such as Scrum. 

The five values of XP are communication, simplicity, feedback, courage and respect. 

There are thirteen basic practices that explain what extreme programming is. 

  1. Whole Team 
  2. Planning Game 
  3. Small Releases 
  4. Customer Tests 
  5. Simple Design 
  6. Pair Programming 
  7. Test-Driven Development 
  8. Design Improvement 
  9. Continuous Integration 
  10. Collective Code Ownership
  11. Coding Standard 
  12. Metaphor 
  13. Sustainable Pace 

Pros 

1.Ability to react quickly to new technologies, 

2. Great freedom for programmers, thanks to which they have the opportunity to demonstrate their own creativity and experience, 

3. Bugs are generally looked for earlier, so it is much easier to fix them without affecting the rest of the code, 

4. No need to create system specifications, only the code and tests count, 

Cons 

1. There may be more or less serious complications caused by misunderstandings about customer expectations 

2. The constant evolution of the code and the technique itself carried out with too much freedom may lead to a less optimal code 

3. Programmers are different people, some may not be able to write without prior preparation, or they just prefer to make some plans first, the problem may also be the lack of involvement of even one person, 

4. The code is shared – this means that anyone can make changes to any part of it. 

As you can see, the topic of software development methodology is very wide. We hope this article has allowed you to delve even deeper into the subject and dispelled many doubts.
