How Agile Methodology helps in Software Product Development?
Requirements are essential part of Software Product Development, and success of a product largely depends on requirements. Requirements-related issues are often named among highest risks of software product development.
The main risks with the requirements are typically connected to missing some requirements,defective or dubious requirements, or requirements that conflict with one another. Working with such requirements leads to wrong product creation, and it will take pretty much time, effort and money to correct mistakes, or even redevelop the product from scratch. This surely sounds really unpleasant. However, the situations like described above, are not rare in the area of software product development.
How can Agile Development methods help?
Agile development methods, when they are suitable for the occasion and implemented correctly can help mitigate those risks. I’m not telling that Agile is the best methodology for software product development ever seen. As any other methodology it has its pros and cons, and there are plenty of Waterfall methods that do great, when they are suitable for the situation. I mean, when the requirements are not finally defined, and there’s a high possibility that changes will be introduced, etc., Agile may really help.
As a rule, Software Development Services involve lots of requirements. However, not all of them will be implemented, and most of them will be revised and changed. Changing requirements, in fact, is developers’ pet peeve. As Agile Methodology implies iterative approach to software product development, developers analyze and work with requirements defined for this exact iteration.
The customer, commonly involved in iterations planning, is available to discuss and explain questions related to requirements. If there were some misconceptions or controversies, there’s a chance for developers to find out what the customer meant by “it should perform… you know…the thing like… well, it should be just great!” It was a joke, but you see my point.
Thus, the required functionality is implemented into the product by small parts, giving both developers and customers clarify blear moments, and giving customers the possibility to introduce changes painlessly for the team involved in their software product development. These are essential parts of software development, and success of a product largely depends on requirements. Requirements-related issues are often named among highest risks faced by a Software Development Company.
Some of the principles behind the Agile Manifesto:–
- Customer satisfaction by rapid, continuous delivery of useful software
- Working software is delivered frequently (weeks rather than months)
- Working software is the principal measure of progress
- Even late changes in requirements are welcomed
- Close, daily cooperation between business people and developers
- Projects are built around motivated individuals, who should be trusted
- Continuous attention to technical excellence and good design
- Simplicity
- Self-organizing teams
- Regular adaptation to changing circumstance
Software Product Development Architecture – Why is it important?
Architecture is an integral aspect of software development. The architecture is not the operational software, rather, it is a representation that enables a software engineer to analyze the effectiveness of the design in meeting its stated requirements, consider architectural alternatives at a stage when making design changes is still relatively easy and reduce the risk associated with the construction of the software product.
Architecture serves as the blueprint for both the system and the product developing it, defining the work assignments that must be carried out by design and implementation teams. The rchitecture is the primary carrier of system qualities, such as performance, modifiability, and security, none of which can be achieved without a unifying architectural vision. Architecture is an artifact for early analysis to make sure that the design approach will yield an acceptable system. Architecture holds the key to post deployment system understanding, maintenance, and mining efforts. In short,architecture is the conceptual glue that holds every phase of the product together for all its many stakeholders.
The Goals of Architecture
Product architecture seeks to build a bridge between business requirements and technical requirements by understanding use cases, and then finding ways to implement those use cases in the software product. The goal of architecture is to identify the requirements that affect the structure of the application. Good architecture reduces the business risks associated with building a technical solution. A good design is sufficiently flexible to be able to handle the natural drift that will occur over time in hardware and software technology, as well as in user scenarios and requirements. An architect must consider the overall effect of design decisions, the inherent tradeoffs between quality attributes (such as performance and security), and the tradeoffs required to address user, system,and business requirements./p>
Any Software Development Company should keep in mind that the architecture should:
- Expose the structure of the system but hide the implementation details.
- Realize all of the use cases and scenarios.
- Try to address the requirements of various stakeholders.
- Handle both functional and quality requirements.
The Benefits of Architecture
When you take the time to properly design, implement, document, and evaluate software
architecture for Software Product Development, you can
- predict, achieve, and control quality attribute behaviour and make practical tradeoffs early
- greatly reduce the failure rates of software projects
- produce a rationale for certain architectural decisions made or not made
- communicate with your stakeholders
- reason about and manage change
- enable more accurate cost and schedule estimates
- create evolutionary prototypes
- predict and mitigate risks
- understand the tradeoffs inherent in the architectures of software-intensive systems
- provide insight into how quality goals interact—that is, how they trade off
- plan your staffing needs for Software Development Services
