Developed by the developers for the developers!
Favoured by software developers, Agile methodology has become a prominent part of the software development process. The term ‘agile’ has more connotations attached with it and is no longer just a word to refer ‘the ability to move quickly or easily’ in the dictionary. It has become an integral part of the management programme and so is implemented by almost 70% of the companies working in the same field. Agile Methodology was designed by 17 software developers in 2001 to solve the generic complexities faced by the developers. Thus, they came up with Agile Manifesto which had 4 basic values and 12 principles which being obeyed accurately will result in a robust delivery of the product and that too without any fault or failure.
4 values Explained
#Individuals and interactions over processes and tools
Communication can solve many problems single-handedly; therefore, the foremost value of Agile is to value individuals and interaction more than processes and tools. The development undergoes via individuals and they are the best who know about the business and demands of the clients. Henceforth, Individuals & interactions should be valued more than processes and tools.
#Working software over comprehensive documentation
Long documentation has always been a cause of concern for the product delay. The development team had to wait for days before starting the work which caused unnecessary wastage of time. Therefore, this value came into significant importance to highlight that the working software should begin alongside the documentation. It doesn’t ask for neglecting documentation but prioritises the working software over comprehensive documentation.
#Customer collaboration over contract negotiation
Agile methodology leaves room for customer collaborations and permits in between changes during the development procedure. Nevertheless, customer should always be a priority for any business organisation; therefore, the customer gets a chance to be involved in the development process which further ensures the chances of customer’s utmost satisfaction with the delivered product.
#Responding to change over following a plan
Since the agile methodology itself is not based on strict rules and regulations; henceforth, it does not allow to follow any strict plan as well. The development team or anyone associated directly with the product has every right to ask for plan change if he/she can see faults in the ongoing plan. Thus, responding to change over following a plan became one of the 4 values to be followed under agile methodology.
12 Principles of Agile Manifesto
#Our highest priority is to satisfy the customer through early and continuous delivery of valuable software.
‘Robust’ now a common term for the software developers has come into limelight only through the agility of the development procedure. This principle emphasizes on delivering the product either early or on time. Customers are usually satisfied when they get their deliverables at regular intervals.
#Welcome changing requirements, even late in development. Agile processes harness change for the customer’s competitive advantage.
Agile Methodology accommodates the changes that need to be made as per the requirement of the client and feature the same in the product. Client satisfaction should be prioritized.
#Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.
Using scrum events, regular delivery of working software is essential. At every sprint, the scrum team must guarantee to deliver if not complete but at least a part of the working software.
#Business people and developers must work together daily throughout the project.
Clarity on both sides is a key to successful product development and delivery. Therefore, the agile manifesto emphasises the importance of working hand in hand relationship between business stakeholders and development teams.
#Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done.
A key to becoming a successful team is to trust, support and motivate each other. Every team member should feel passionate about his job otherwise it can affect the development of the product.
#The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.
Chinese whisper is the game we all have played and we all know how it results in the end. Henceforth, agile methodology promotes face to face communication over hierarchical communication in order to prevent misunderstanding.
#Working software is the primary measure of progress.
The progress report of the development procedure should only be prepared on the basis of the working of the software. No other parameters should be taken into consideration.
#Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely.
A perfect development speed should be maintained throughout the development process. Each and every release should be done at regular intervals and the sustainability of the same should be maintained throughout.
#Continuous attention to technical excellence and good design enhances agility.
Two major elements of the development cycle should be perfect usage of technical skills and a good design should be ensured to coordinate for the peaceful improvement in the released working software.
#Simplicity–the art of maximizing the amount of work not done–is essential.
Simplicity should be preferred over complexity and the focus should be on completing the job on time rather than delaying it. Any step that seems irrelevant should be removed from the process which will further save time and money.
#The best architectures, requirements, and designs emerge from self-organizing teams.
The hierarchy should not be followed and the team should be skilled enough for self-organization. Communication barriers and hierarchies should be lifted in order to produce a sense of clarity in the team.
#At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behaviour accordingly.
A self-quality check should be adapted in order to minimise the chances of a failed release at the end. And, the team should ensure that their working plans are producing the right amount of productivity and energy in the group.
