Top Software Development Methodologies – Advantages and Disadvantages
What’s Software Development Methodology?
It’s the methodology or structured processes that make up the development of a given software result or design. It combines design gospel and practical, realistic ideas that aim to produce an systematized system of software development.
There are different methodologies grounded on colorful approaches, that were introduced over the times.
Software development methodologies or software development life cycle give a structure for inventors and contrivers to unite and grease effective cooperation. They also help to produce a formal communication platform and define how word is changed among platoon members.
While utmost software development companies admit the need for a methodology, opinion remains divided as to which system is the stylish; after all, every system has its benefits and downsides.
The most suitable methodology also depends on the pretensions and requirements of the platoon and the design, and the platoon structure. A company may also employ different styles for colorful systems.
Need of Software Development Methodologies
One can say that it’s imperative to not just elect an applicable software development methodology, but to also apply it duly and in a discipline across the software development life- cycle of theproject.However, it could prove disastrous, If done aimlessly.

Without a proper structure, there’s a advanced chance of miscommunications, and having to incorporate frequent changes in design and functionality because of client requests.
Modifying the software multitudinous times can impact the design negatively – especially in terms of cost and time. It could lead to waste and duplication of trouble, and inordinate expenditure and time spent, which eventually results in an operation that’s not high quality.
Software development methodologies aim to profit guests too – and not just the inventors. Choosing the optimal methodology helps insure that both sides are on the same runner and that all the factors are duly estimated before taking any major decision.
Methodologies help make the entire process more effective, and provides a precise timeline for delivery; it also empowers the platoon so that they do n’t reply to all the inputs they admit, but rather, make them more methodical and controlled
Let’s now claw into the different types of software development methodologies or SDLC styles and examine the benefits and downsides of each.
- Waterfall Model Methodology
This is one traditional software development model which has its origins a couple of decades ago – still, it’s still relatively popular, and useful indeed moment.
It takes a simple and direct approach, with different phases of development split into flowing and chronological processes. It’s also easy to understand and follow and is ideal for brigades with inexperienced inventors.
One stage has to be completely completed before the coming bone can be started. Only after all the conditions are established, can the designing work begin. The name is chosen because it’s auni-directional inflow – it’s one way, no going back. It isn’t flexible.
Advantages of Waterfall Model
It’s direct and easy to understand, and ideal for new inventors
All specifics and deliverables are defined before work starts
With the clear description, there’s little compass for miscommunication of information
Disadvantages of Waterfall Model
Without taking client feedback in the original stages, there’s a possibility of the design going moving down from the target.
After development is completed, only also testing is conducted; this could make fixing of certain issues problematic
As a rigid model, it’s delicate to make changes, and presumably infelicitous for complicated systems
The platoon may end up spending too important time establishing rather than working on the result for the end- stoner’s problems.
The cascade model is suitable for systems with well- defined compass; where every demand is spelled out easily; when the issues are predictable; and when you do n’t have enough experience in the platoon.
- Prototype Methodology
This is one of the most current software development life cycle methodologies in vogue moment.
This approach allows inventors to produce prototypes of the factual product, and it’s put to test by factual guests, whose feedback is taken. Grounded on this feedback, the prototype is tweaked and meliorated several times, till the client is satisfied.
The main reason for its fashionability is the total evaluation it undergoes before factual development begins, as this can uncover implicit issues, and gives time to the development platoon to fix them.
It’s important to note that the success of this model depends to a great extent on how well the platoon communicates with the guests in the process of testing the product. The cost of the prototype development is frequently borne by the development platoon.
Advantages of Prototype Model
All possible problems can be detected beforehand on, minimizing chances of product failure
Ensures client satisfaction before factual development begins
Helps make good relations with the client from the early stage
Enables gathering of detailed word and conditions with the prototype, which is used for the final product
Disadvantages of Prototype Model
Inordinate testing and feedback taking can increase the delivery timeline
Client prospects can suffer drastic changes and may not be in sync with the prototype at all
It may push up the expenditure and go over the budget
This software development methodology is perfect when there are several variables and unknown factors at play in the design – like, a portal with heavy stoner commerce.
This approach can help you discover what druggies like best, and alleviate the threat of product failure. It’s ideal when you ’re structure software with numerous unknowns.
For illustration, an online platform with violent stoner commerce. With the prototype model, you can find out what works best with druggies and reduce the threat of developing the factual product.
- Spare Development Methodology
This model stands out among the different types of methodologies in software development, as it surfaced from the principles of spare manufacturing by carmaker Toyota, and concentrates on boosting productivity while dwindling destruction.
Grounded on this, inventors avoid conditioning that aren’t productive and insure high quality in their work.
It also stresses the need to learn continuously, and to not take opinions in haste without knowing all data – being open-inclined and gathering every possible bit of information is critical in this system.
Then, inventors need to pinpoint roadblocks that could potentially stymie the process, with the end of establishing an effective, indefectible system.
Spare development also stresses communication, platoon collaboration, and collective respect.
Advantages of Spare Model
Minimizes destruction, like dispensable attestation, repetitious conditioning, and redundant canons.
It brings down overall expenditure on the design

Promotes effectiveness and productivity and pets up reversal time
Platoon members are vested with lesser decision- making powers, motivating them to do further
Disadvantages of Spare Model
You need an expert platoon of inventors for this model to succeed
The liabilities could overwhelm less educated inventors and they may lose focus
Total attestation is needed which can burden the judges and inventors
Spare development as a system development methodology is ideal when you have a lower design with a rigid or small budget – and an educated platoon of inventors.
You need to squeeze the most out of a lower platoon to get great results with further effectiveness and minimum destruction. This isn’t practical for large systems, as large brigades are needed to complete multitudinous tasks.
- Agile Development Methodology
This is presumably the most popular of the software development models in use moment. The approach is relatively different from the traditional direct system.
Rather than stressing the attestation and inflexible procedures, this system focuses on satisfying the end- stoner.
Nimble breaks tasks into short‘sprints’of about a week to 4 weeks; an iterative approach that ensures multiple testing throughout the development process. Client feedback is taken at specific destined intervals, and changes are made consequently.
This model prioritizes communication among all stakeholders, like inventors, guests, druggies,etc.
Advantages of Agile Model
Minimum excrescencies or crimes thanks to iterative testing and nonstop forfeiture-tuning
More understanding and collaboration among platoon members, due to translucency and ease of communication
Any changes needed can be taken care of fluently without impacting timelines and budgets
Significant enhancement in the quality of the product developed.
Disadvantages of Agile Model
There could be too numerous requests for changes, and the inventors may get overwhelmed
With lower stress on attestation, in the after stage of development this may produce problems.
Too numerous conversations and review sessions can take time down from core conditioning
It’s not easy for inexperienced or fresh inventors as the approach isn’t strictly structured
Nimble software development methodologies are suitable for systems that bear quick change; it’s also great when you want to develop software in a new niche. Nimble workshop best when you want to incorporate fresh ideas to keep in step with request trends and conditions.
Still, it authorizations that you need educated inventors able of working singly in an terrain that isn’t structured and is veritably presto- paced.
- Rapid Application Development (RAD)
Launched in 1991, this approach to software development actually was the base for the ultramodern iterative methodologies like Agile.
The RAD model is each about icing product development as snappily as possible, with zero negotiations on quality. This frame has four phases
Supporting design conditions
It’s not a direct model, and hence stresses on developing prototypes first, and getting the client to test them.
The model goes through several duplications till the customer is satisfied. Thanks to the rigorous testing and feedback entered, the development platoon can alleviate pitfalls and produce a product that’s nearly indefectible.
Following this approach can affect in a successful product rollout within the destined delivery timeline.
Development tools able of robotization and streamlining the process of development are frequently used by brigades that follow the RAD model of software development.
Advantages of RAD Model
Reduce threat of product failure through testing and client review
Greater client satisfaction
Ideal for apps that are small and medium sized
Shorter reversal time for design
Disadvantages of RAD Model
Too important dependence on client response
Endured and largely professed platoon is a must-have for this system to succeed
Only possible for systems with flexible or large budgets
No attestation to track progress
The RAD software development methodology works best when you have a largely professed and educated platoon and guests who are involved in the development process and are quick to respond.
It’s important to maintain a good communication inflow for this approach to succeed. You’ll need to invest in a many tools that will help quicken the pace of development.
- Dynamic Systems Development Model
The RAD can be considered the precursor of the dynamic system model; it’s a slightly refined form of the former and focuses on the prompt delivery of the design.
This approach also aligns with the business conditions and the design pretensions.
There are four stages in this methodology of software development
Feasibility and business study
Developing a prototype
Designing and developing
Just as in the former model, the end druggies’feedback is taken throughout the development process, dwindling the threat of moving down from the pretensions and conditions of the design.
This model also includes detailed attestation which is absent in the iterative or Nimble approaches.
Advantages of Dynamic Systems Model
Thanks to the iterative approach, the inventors can insure the prompt delivery of introductory functionalities
The timeline and budget can be better managed by development platoon
There’s acceptable attestation that’s created during the design life- cycle
Proper communication is established between the inventors and druggies, helping the platoon stay on track.
Disadvantages of Dynamic Systems Model
Costs may be advanced
Heavy involvement is demanded from both druggies and inventors
Larger brigades are more likely to succeed than small bones
It’s a complex conception, as is the deployment of the model

The Dynamic Systems Model can be used by large associations which are embrangle down by red-tapism and redundancies. This approach helps break down rigid processes into manageable, iterative corridor, streamlining communication among colorful brigades.
- Scrum Development Methodology
Among the different methodologies of software development, Scrum is maybe the most flexible bone.
Grounded on the Nimble model, it has incremental as well as iterative approaches and involves the Development Team, Scrum Master, and Product Proprietor.
The product proprietor is analogous to the design director – takes feedback from the client and makes sure that the platoon is clinging to their conditions.
Scrum Master is a facilitator who familiarizes the platoon with the process of Scrum development. And the platoon is in charge of developing the design.
What makes Scrum stand out is that tasks are executed in sprints, with each sprint lasting 4 weeks.
The rapid-fire prosecution enables brigades to descry problems, suggest remedies, test them, and take feedback snappily and speeds up design development.
Advantages of Scrum Model
Problems can be resolved snappily thanks to short duplications
With regular feedback included in the process, it’s largely responsive to changes
It’s cost-effective and boosts productivity and effectiveness
The platoon members are brought to the same runner always with regular meetings
Individual benefactions are noticed and given credit in the meetings
Disadvantages of Scrum Model
For Scrum to work, every platoon member needs to be inversely complete, and committed
Frequent meetings can be a burden
Without strict control on timelines, reversal time may increase
It’s only suitable for small systems
Proletariat is ideal when conditions aren’t well defined and may bear frequent changes. It’s suitable when you have an expert platoon that’s completely committed, and you have lower systems.
- Helical Model
The helical model is flexible in the sense that the inventor can make variations in the design indeed in the after stages.
As the name indicates, we’ve a indirect circle through which the inventor will look for the perfect design and will continue the same until he gets the product which reduces the threat factor.
At every point, he could find vulnerable positions which can be answered or exclude.
Advantages of Helical Model
Reduces the threat factor and suitable for large systems
Redundant features can add at any replication.
It can work out with massive systems.
Disadvantages of Helical Model
Suitable only for expensive systems
May continue with the indefinite rotation
Fault in the threat analysis affects the whole design
- Extreme Programming Methodology
In an unstable design terrain, this extreme system will be the stylish choice which includes four essential subtopics like rendering, testing, designing, and harkening.
The completion of the design will be briskly then, and the feedback from the guests are also be collected at every phase, and the demand can be incorporated without important pressure.
Advantages of Extreme Programming Model
Lowers the cost of the overall design
Makes the inventors able of satisfying all the norms
Lower time consuming
Makes testing phase easier
Disadvantages of Extreme Programming Model
Changing the demand in the after stages will be precious
Not suitable for conservation and short systems
The inventor will find it delicate to come up with the model
- Rational Unified Process Methodology
The entire design divides into five distinct phases videlicet
Design and Analysis
Proper guidelines for the inventors in form of templates are the added advantage where step-by- step processes and exemplifications regarding each stage are described.
Quality testing is also considered with each phase by the object- acquainted program.
Advantages of RUP Model
Able of fixing the crimes that passed due to the changes from the customer side
Integration is associated with every stage, so no separate time frame is demanded
Exercise of peripherals reduces the overall time
Disadvantages of RUP Model
Complex stages are evolved.
Confusion in integration occurs because of the multiple development design platoon.
In the case of rearmost technology operation systems, supplemental exercise is insolvable.
- Point Driven Development Methodology
Iteration system in collaboration with the object- acquainted conception is the core of the point- driven way.
It tracks all the mileposts declared at the original stage. Before framing the sphere models, the compass of the system will make at the foremost.
Advantages of FDD Model
Can fluently handle complex systems
Time consumption is comparatively less
5 point process improves the performance
It includes up-to- date ways.
Disadvantages of FDD Model
Not suitable for small systems
The Team Leader will hold the entire epitome so that the success or failure depends on his capability
- Joint Application Development (JAD) Methodology
JAD sessions are the highlights in these software development methodologies that produce an commerce space between the client and the development platoon which makes the client gets involved in the development phase too.
At every stage, the client can make suggestions. JAD was applicable only for the system operations, but now it’s used in every possible process indeed in web- grounded operations.
Advantages of JAD Model
Each session will make the client and inventor evolved in the design
JAD creates high- quality affair with a limited period
The development process will be briskly with many crimes
Disadvantages of JAD Model
It takes time to apply the session since proper planning requires between the platoon members
Well educated professionals are demanded
- V Model
The V- shaped successional process that evolves in this system is generally called a confirmation or verification process.
Each phase is concluded with the test process and is suitable for low to medium-sized systems. In resemblant with the planning and deployment, the testing phase is enthralled.
It includes four important types videlicet
Advantages of V Model
Early discovery of the crimes
Easy to apply
Suitable for small systems
Disadvantages of V Model
It’s the Least flexible or rigid model.
Changes in the middle of the development phase will produce significant issues
Creating error reports at the earlier stages is time- consuming

Which Software Development Methodology Should I Use?
As mentioned before, the specific methodology to use depends on the type of design you have to develop, its compass, your platoon members and their skill and experience, and so on.
Going through the below- mentioned methodologies, you’ll be suitable to pinpoint which approach will work stylish for you. You may indeed need to change the approach for different systems.
The different software engineering methodologies are attendants as to how to approach software development; they’ve been around from the time programming began, and are still important moment.
Through the times, colorful methodologies have been introduced, but there’s no single bone that can be said to be better than the rest, as each has its own pros and cons. The selection of a methodology depends on multitudinous factors like design conditions, budgets, pretensions, platoon structure, and experience,etc.
