From the early 1950s till the present, there are more and more different software development methodologies introduced within the tech industry.
In most cases, all those were firstly presented during the past decades, when a particular case required the use of a new development model that can fully meet the project’s characteristics, requirements, and goals. And, all the innovative approaches used were to make the development more productive and boost the desired results.
By the end of 2021, the IT spending on enterprise software is expected to reach over $600 billion worldwide, with a CAGR of 13.6% compared to 2020. As a substantial amount of these costs are invested in the software development branch, developers are now looking for the most optimized and effective methods of software creation.
Different types of software development methodologies can significantly eliminate the time, resources, and costs needed for the project realization. However, due to the vast number of these methodologies currently existing, it becomes more and more challenging to pick up the best model for each specific case.
In this article, Intellectsoft’s best experts will analyze all the available different software development methodologies within the industry, as well as define their strong sides and possible drawbacks so you could come up with the most beneficial yet efficient approach that ideally fits your project.
Let’s get it started!
What Is a Software Development Methodology?
To understand the types of development models existing, it’s important to learn the project development basics first.
The software development methodology refers to the development SDLC (software development life cycle) model, which is focused on organizing beneficial yet effective project development processes from the idea and planning to front-back & back-end development, testing, and software launching.
In other words, it is a so-called app development lifecycle that applies different formats, approaches, and techniques and helps to:
Effectively organize the workflow
Eliminate time for the project development
Reduce the costs needed to develop a software
Track the process of creation
Provide a set of norms for the effective communication
Improve the quality of the final product and more
Today, there are 12 standalone types of software development methodologies that introduce different models of project creating. However, each of those has its unique advantages and possible drawbacks, so it’s essential to analyze the core gist of your project as well as learn the pick up the most effective
As for 2021, one of the leading technological approaches practiced for software development is DevOps methodology, which is used in every third project (35.9%), says Statista.
But, in practice, it’s more efficient to review all the options available on the market and define which of the software development methodologies can fit your program best.
Types of Software Development Methodologies
As you already know, there are various types of different software development methodologies aimed at improving SDLC.
However, having reviewed them you can find out there’s no one outright winner – for each specific case, the strategy will be different based on the project’s characteristics, requirements, main goals, core features, and more.
Thus, the detailed comparison of software development methodologies can simplify the choice and help you to define the most winning option for each app development project individually.
#1. Agile Software Development Methodology
The main focus of this methodology is the project/product itself. That is why, it presupposes various constant alterations based on users’ and customers’ feedback, as well as internal changes related to the work of engineers.
The agile software development methodology is free of rigid frameworks on the one hand. While, on the other hand, the software development process is divided into short time boxes, thus offering the real results and feedback truly fast.
Problems are detected and fixed at the early stage
Higher flexibility to the plan and easier adapting to different project changes
Eliminated time of project deliverables
Enhanced communication with the clients, and their close engagement to each stage of the software development process
Top-notch quality of the final product
Mostly fits smaller, young companies that are more flexible and open up for the active communication
Lack of understanding the solution specifics before their implementation
The high risks of ignoring the project documentation and requirements
Insufficient predictability of the budgeting, marketing plans, sales, and more
Requires immediate responding to issues and feedback in real-time
Easy to get lost in details and be pulled off the project course
#2. Waterfall Development Methodology
The absolute opposite to the previous approach, this methodology is strict and linear. A new stage can only be started if the previous one is completed. In other words, each phase gradually flows into the next one.
What is more, there is no going back to the previous stage. This approach is easy to understand as it presupposes a strict sequence of completed tasks. Waterfall software development methodology is often regarded as a classic representation of software development.
The project plan is simple and straightforward, with all the goals, requirements, and important aspects defined before the software development process
All the processes are easy to understand
Enforced discipline and better keeping the timelines
All the steps of testing scenarios are planned in advance
No financial risks due to the high planning accuracy
The outcomes are easy to predict, as they meet all the requirements and criteria outlined in project documentation, so the companies get exactly what they were expected to develop
The planning stage can be too challenging to organize the entire process
Low flexibility and inability to implement the changes once the software development process is started
The immediate changes to the project can result in additional spendings that are usually enormously high
A longer time of delivery
Weak for long or ongoing projects
#3. Extreme Programming Method
A perfect approach for unstable projects, as it implies involving the customer as much as possible. What is more, it presupposes considerable flexibility.
Extreme programming methodology is believed to boost the quality of software owing to its ability to adapt to dynamic changing demands. In addition to that, constant feedback and communication is the key to an efficient and happy team environment.
Significant customer involvement results in high-quality products
Stable final product due to the continuous software testing
Pair programming eliminates the errors that may occur during the software development process
High level of flexibility and the ability to immediately implement the changes
Code stays clear and comprehensive
No rush to keep the timelines – developers work at their own pace
Efficiency is much dependent on the people involved
Vague and unknown future results
Clients must always be engaged in the software development process
Comparatively large time and high costs investments
Is too challenging for the small teams, as they might not possess all the necessary skills and knowledge
#4. Lean Development
Value for the client is the essential core element the whole approach revolves around. If something is worth it, it should be done immediately; if not, it should be removed.
Lean software development methodology focuses a lot on loss reduction. That is why the whole project is examined significantly beforehand to eliminate any wasted time or money. As value is the core component, feedback plays a crucial role itself, so that the actions are taken fast.
Perfect for a low-budget project and rigid time limitations
The team is focused on delivering the on-demand tasks
Provides fast deliverability by eliminating the waste and useless processes
Is easily scalable – ideally fits for large projects, unlike most of the other software development methodologies
Cutting out tasks allows getting more time for the core processes and implementing the high-value features to the final product
Enhanced teamwork enables focusing on meaningful and impactful work with a greater sense of purpose
Success is much dependent on the working capacity of a team
Low experience and lack of expertise might not work if the team works independently
Cutting too many things can lead to a loss of project focus
Risks of the delays due to certain bottlenecks or low resource levels
Requires excellent documentation to ensure all the aspects are developed correctly
#5. Prototyping Methodology
Based on the waterfall approach and having a significant focus on customer feedback. There are some initial requirements, developers provide samples, and only after customers evaluate the functionality of samples, the final development begins.
The gist of this software development methodology lies in the name itself – prototype methodology. In other words, before getting down to business, there will be painstaking research and prototyping to avoid unnecessary risks.
The prototype model can become a great information source for the UI/UX improvements
Enhances the system functionality by analyzing the actual look and feel of the system being developed
High involvement of clients and final consumers during the developing process
Easier and more effective detection of errors and issues
High flexibility of the app developing process, that enables adding the missing functions or redoing the existing ones
Reduced time and costs due to the early detection of the critical issues
Too much client involvement can affect the process by slowing it down
Possible budget increase, as the management cost may go beyond the money limit
Increased complexity system that can enlarge beyond the original plans
Developers can reuse the existing prototypes that don’t always meet the client expectations instead of creating the new product from a scratch
The risks of the development overdoing with too much effort, time, and costs invested
#6. Dynamic Systems Development Method
There are two main focuses: strict time frame and assigned budget. The idea is to manage to provide successful and effective software within a particular time limit and not exceed costs. Users’ involvement is of high importance as well. The dynamic systems model presupposes continuous feedback to deliver maximum functionality within the agreed requirements.
Time-boxed yet predictable project deliverability
Developing processes are delivered at a standard level of quality, that can be improved through the analysis of documentation, software testing, and periodical reviewing of the outcomes
Great communication between developers and clients
Reaching the needed functionality as fast as possible
Producing enough design work upfront (EDUF) to get a more concrete idea of what product client needs
High control under each stage of the project development
Requires considerable costs for development
The approach will not fit and meet the needs of a small organization
Doesn’t stimulate the developer creativity
Projects are mainly focused on complying with the documentation and standards while can neglect some of the more sophisticated options available
Requires an experienced team of developers with deep expertise in both business and technical aspects
#7. Feature Driven Development
Features are regarded as a sort of user feedback. Planning, designing, and building are all feature-based. This approach involves iterations to boost functionality and deal with varied complexities. Feature driven development aims at organizing the work of a large number of teams within a big organization.
Mostly fits large-scalable, long-term, and ongoing projects
Provides a detailed understanding of the project’s scope, major goals, and context
Breaks the feature sets into smaller chunks and regular iterative releases, thus reducing the risks of errors and enabling delivering the specific features in shorter time frames
Utilizes the pre-set standards to simplify the developing procedure
Enables any developer with appropriate experience and expertise to handle the tasks
Based on a user-centric approach, where the outcome depends on the user opinion
Cannot be applied by small organizations and for smaller projects
Requires several experienced developers to monitor the process
Difficult to guarantee a strict deadline
Doesn’t provide the written documentation for the clients, only the communication among the developers during the project launching cycle
Is more focused on individual code ownership instead of the shared team model
#8. Rational Unified Process
The idea of this approach lies in having four stages of the developing process. ‘During each of the phases, all six core development disciplines take place – business modeling, requirements, analysis and design, implementation, testing, and deployment’, according to study.com.
The main focus of this software development methodology is to craft an effective software of high quality without expanding the budget and missing the time frame.
Provides reliable, accurate, and strict documentation
Eliminates the risks by taking into consideration the clients’ evolving needs
Requires less time for integration when completing the software development life cycle
The reuse of components allows reducing the time of project completion
This development model can be studied through the online pieces of training and tutorials available on the Internet
Incorporates the most effective practices of Waterfall by combining them into a more iterative process that is more flexible for changes
Requires an expertized yet well-trained developer for this methodology to ensure the project success
It May be too difficult to make the head or tail of the rational unified process model
This development model doesn’t allow to reuse of the pre-made components
Not effective for the big projects with multiple development systems, as it can cause more issues and confusion during the testing process
The delivery process may be too time-consuming for certain types of projects
#9. Spiral Development Model
The main idea is to eliminate the risks at the early stage of the project. The developing procedure goes from smaller levels to the big ones gradually. This approach combines waterfall ideas with iterations.
Each stage involves setting the goals and receiving feedback from a client. Moving from one phase to another in a spiral model implies completing and removing the risks before moving forward.
Best fits to mission-critical and long-term projects which requires the professional risk analysis and thorough control
The process of the estimation of the costs is pretty easy yet straightforward
Features the fast achievement of the progress
Repeated development helps to eliminate the possibility of risks and effectively control the system quality
The specific functions or changes can be implemented at earlier and later stages
Leaves a lot of improvement opportunities taken from the customer feedback
Not suitable for small organizations and projects
The danger of failing to meet the agreed budget and time limit
Requires accurate following the spiral model project development protocol
Demands a strict risk assessment expertise
The correct risk analysis can be conducted by the expertise developers only
#10. Joint Application Development
This approach implies significant interaction between users, designers, and developers. There are workshop sessions to facilitate and increase the developing process. During the session, the following people are involved: a facilitator, end-users, developers, observers, mediators, and experts.
What is more, in joint application development there is a considerable focus on eliminating errors at the early stage, thus saving the expenses needed to correct the mistakes later on.
Valuable information is achieved within a short period
Immediate elimination of errors and resolving the differences, which greatly boosts the software quality
Features accurate project requirements focused on improving the system quality
Reduces the time and costs needed for the project development
Enables close communication between the team members and client, which greatly speeds up the development process
Allows team members to push each other for faster yet high-quality deliverables
Can be quite a time and energy-consuming model when it comes to planning
Requires significant budget for the project launching
Needs highly experienced and expert professionals
Depending on the project size, it can be more difficult to align goals and maintain the overall project picture
The clients usually make a huge laundry list of demands with making them all “high-priority”
#11. Scrum Development
Easy to understand and effective when it comes to achieving results. The working process is divided into sprints. All the assignments for each sprint are set beforehand and are then discussed after this period.
Thanks to this approach, it is easy to get a response to emerging problems early, and as a result, solve them immediately. Scrum software development methodology is by far the most flexible. For this reason, it easily deals with projects having changing requirements.
All the stages and processes are clear and transparent
Light control goes together with constant updating that keeps all of the team always on guard
Removing the errors and project issues becomes much easier
Implies high engagement of clients
Enables frequent updates of the progress, which are proposed on the regular meetings
Clients can trace the various project processes and measure the development performance
The costs and time needed can often be uncertain
No deadlines for the product delivery
Big projects cannot be managed with this approach
Only expert professionals that are constantly up to the tasks can be involved, with no beginners
The test team must conduct regression testing after each sprint, which is one of the most notable difficulties of this methodology
#12. Rapid Application Development
It is clear from its name that the main goal of this approach is to achieve fast results. To do so it uses the assistance of other development methodologies. It focuses on fast prototype releases and iterations.
As a result, quick feedback is received, errors are eliminated and the desired results are reached. It is as flexible and adaptable as possible. The main focus is to adjust so that the software is crafted, functional and effective fast. Rapid application development methodology includes 5 stages: analysis and quick design, prototype cycles, testing, and implementation.
The client is encouraged to take fast reviews and constant feedback for the improvements
Enables easy change of the core functions when the software is in the testing phase
Minimizes the risks since the early stages of development
Reduces the time of development by setting the deadlines for the project completion
Is mainly focused on delivering the business problems important for the end-users
Applies the use of automated tools that allows creating the prototypes easier and much quicker
Not suitable for small projects
Requires highly expert developers and a strong collaboration between the teams
The stages are not strictly defined, which impacts the overall project structure
The development costs are comparatively high
All the requirements should be outlined before the development process starts
