What are Software Delivery Models?

Software delivery models are strategies the organization employs to get the software product ready for the industry. They are useful for identifying issues in software development before they are recognized in the final phase. The model used has a significant impact on the project’s quality, schedule, spending plan, and potential to satisfy the demands of the stakeholders. These models are also referred to as SDLC models or techniques, which stand for Software Development Life Cycle. The size, nature, and complexity levels of your project will all influence the appropriate software development model for it. The purpose of the various delivery models is to organize the workforce so that they can work as effectively as possible.  after selecting a software development model and methodology, there are many other steps to go through before delivering final outcome. There are certain phases to pass through: analysis, design, development, testing, approval, execution, and maintenance. We’ll discuss three of the leading software delivery models in order to choose the ideal model for your business 

 

The three software delivery models:

We have compiled a list of the top 3 software delivery models with their phases of the development process after proper research and analysis of various software delivery approaches.

Waterfall Model

It is the oldest software development methodology with a simple procedure. In this model, the stages of software development are logically sequenced so that the end of one step is followed by the beginning of the next. If your project involves private information and human error could have huge consequences, going with the Waterfall methodology would be a wise choice. One of its advantages is that it is perfect for a customer who recognizes the product’s general objective, and the project team, in turn, has a better grasp of the client’s engagement with the product and the space in which it must be used.

Phases Of Waterfall Model: 

  • Analysis Phase
  • Design Phase
  • Implementation Phase
  • Verification Phase
  • Deployment Phase
  • Maintainance Phase

When To Use Waterfall Model?

  • When you are clear about how the outcome should turn out
  • The project is small and simple.
  • If there is a stable environment
  • Resources with the necessary training and availability
  • The employed tools and methods are stable
  • When the risk is zero or minimum
  • When no confusing requirements exist.

Agile Model

As the name implies, agile is one of the leading software delivery models and is more adaptable. Each project is split into brief, iterative tasks called sprints where teams collaborate to deliver different segments of the project at the same time. Companies that are committed to full digitalization end up developing agile methodology inside their business units in order to offer better services at a lower price and in short time frames. Today, more than 70% of organizations use this or that Agile approach in their IT projects.  They place greater emphasis on software testing operations than on comprehensive documentation. Faster delivery of functional software systems is the goal of the agile model.

Phases Of Agile Model: 

  • Planning
  • Design 
  • Iteration
  • Testing
  • Deployment
  • Consider feedback

When to use the Agile model?

  • When the product concept or features are not well specified, agile works well. 
  • when it is necessary to make changes.
  • when it is necessary to make changes. Agile’s ability to allow for change freely is significant.
  • In contrast to the waterfall approach, the agile model requires very little planning before the project begins. According to user feedback, features may be added, changed, or eliminated. This successfully provides the consumer with the finished solution they require 

DevOps.

DevOps functions best when the project’s environment is collaborative and open to discussing ideas.DevOps combines strategies to help organizations produce applications and services more quickly than using conventional software development methods.   The requirement to deliver features to clients more immediately gave rise to the DevOps approach. DevOps is being used in Microsoft Office and Gmail, which both receive constant updates. Under this approach,  teams work together across the entire life cycle, from development and testing through deployment to operations. Its goal is to make sure the project is completed quickly and as error-free as feasible.

Phases of DevOps model: 

  • Planning
  • Building the code
  • Testing
  • Delivering updates
  • Monitoring and logging
  • Consider feedback

 

When to use the DevOps model?

  • DevOps functions best when the project environment is cooperative and open to having discussions.
  • DevOps specialists are in high demand and difficult to find. They may also be costly to recruit as a result.
  • DevOps can deliver productivity and excellent performance for initiatives that would profit from an open, collaborative approach.

 

Final Thoughts

Now you have a clear idea about the leading software delivery models and when to use them. The size, degree of complexity, and other unique needs of your company will determine the appropriate software development consulting methodology. If your product handles sensitive data where a misstep by a human could have adverse effects, Waterfall offers a clear and easy “step-by-step” technique. Businesses that are dedicated to a detailed digital transformation end up implementing agile methodologies. And  DevOps can deliver your project swiftly and without inconvenience if your firm has a collaborative culture. The most effective delivery strategy for your project will rely on your objectives, demands, budget, and the availability of the right talent.
