What is agility

Agility includes effective, that is, rapid and adaptive, response to change. This requires effective communication among all of the stakeholders. Stakeholders are those who are going to benefit from the project in some form or another. The key stakeholders of the project include the developers and the users. Leaders of the customer organization, as well as the leaders of the software development organizations, are also among the stakeholders.

Rather than keeping the customer away, drawing the customer into the team helps the team to be more effective. There can be various types of customers, some are annoying, and some who tend to forget what they once said. There are also those who will help steer the project in the right direction. The idea of drawing the customer into the team is not to let them micromanage the team. Rather, it is for them to help the team to understand the user requirements better. This needs to be explained to the customers up front, if they seem to hinder the project, rather than trying to help in it. After all, it is the team that consists of the technical experts, so the customer should understand this.

Organizing a team, in such a manner so that it is in control of the work performed, is also an important part of being able to adapt to change effectively. The team dynamics will help us to respond to changes in a short period of time without any major frictions.

Agile processes are based on three key assumptions. These assumptions are as follows:

  • It is difficult to predict in advance, which requirements or customer priorities will change and which will not.
  • For many types of software, design and construction activities are interweaved. We can use construction to prove the design.
  • Analysis, design, and testing are not as predictable from the planning’s perspective as we software developers like them to be.

To manage unpredictability, the agile process must be adapted incrementally by the project’s team. Incremental adaptation requires customer’s feedback. Based on the evaluation of delivered software, it increments or executes prototypes over short time periods. The length of the time periods should be selected based on the nature of the user requirements. It is ideal to restrict the length of a delivery to get incremented by two or three weeks.

Agility yields rapid, incremental delivery of software. This makes sure that the client will get to see the real up-and-running software in quick time.

Characteristics of an agile process

An agile process is driven by the customer’s demand. In other words, the process that is delivered is based on the users’ descriptions of what is required. What the project’s team builds is based on the user-given scenarios.

The agile process also recognizes that plans are short lived. What is more important is to meet the users’ requirements. Because the real world keeps on changing, plans have little meaning. Still, we cannot eliminate the need for planning. Constant planning will make sure that we will always be sensitive to where we’re going, compared to where we are.

Developing software iteratively, with a greater emphasis on construction activities, is another characteristic of the agile process. Construction activities make sure that we have something working all of the time. Activities such as requirements gathering for system modeling are not construction activities. Those activities, even though they’re useful, do not deliver something tangible to the users. On the other hand, activities such as design, design prototyping, implementation, unit testing, and system testing are activities that deliver useful working software to the users.

When our focus is on construction activities, it is a good practice that we deliver the software in multiple software increments. This gives us more time to incorporate user feedback, as we go deeper into implementing the product. This ensures that the team will deliver a high quality product at the end of the project’s life cycle because the latter increments of software are based on clearly-understood requirements. This is as opposed to those, which would have been delivered with partially understood requirements in the earlier increments.

As we go deep into the project’s life cycle, we can adopt the project’s team as well as the designs and the PHP code that we implement as changes occur.

Principles of agility

Our highest priority is to satisfy the customer through early and continuous delivery of useful and valuable software. To meet this requirement, we need to be able to embrace changes. We welcome changing requirements, even late in development life cycle. Agile processes leverage changes for the customer’s competitive advantage. In order to attain and sustain competitive advantage over the competitors, the customer needs to be able to change the software system that he or she uses for the business at the customer’s will. If the software is too rigid, there is no way that we can accommodate agility in the software that we develop. Therefore, not only the process, but also the product, needs to be equipped with agile characteristics. In addition, the customer will need to have new features of the software within a short period of time. This is required to beat the competitors with state of the art software system that facilitate latest business trends.

Therefore, deliver the working software as soon as possible. A couple of weeks to a couple of months are always welcome. For example, the customer might want to improve the reports that are generated at the presentation layer based on the business data. Moreover, some of this business data will not have been captured in the data model in the initial design. Still, as the software development team, we need to be able to upgrade the design and implement the new set of reports using PHP in a very short period of time. We cannot afford to take months to improve the reports. Also, our process should be such that we will be able to accommodate this change and deliver it within a short period of time.

In order to make sure that we can understand these types of changes, we need to make the business people and the developers daily work together throughout the project. When these two parties work together, it becomes very easy for them to understand each other.

The team members are the most important resource in a software project. The motivation and attitude of these team members can be considered the most important aspect that will determine the success of the project. If we build the project around motivated individuals, give them the environment and support they need, trust them to get the job done, the project will be a definite success.

Obviously, the individual team members need to work with each other in order to make the project a success. The most efficient and effective method of conveying information to and within a development team is a face-to-face conversation. Even though various electronic forms of communication, such as instant messaging, emails, and forums makes effective communication possible, there is nothing comparable to face-to-face communication.

When it comes to evaluating progress, working software should be the primary measure of progress. We need to make sure that we clearly communicate this to all of the team members. They should always focus on making sure that the software they develop is in a working state at all times. It is not a bad idea to tie their performance reviews and evaluations based on how much effort they have put in. This is in order to make sure that whatever they deliver (software) is working all of the time.

An agile process promotes sustainable development. This means that people are not overworked, and they are not under stress in any condition. The sponsors, managers, developers, and users should be able to maintain a constant pace of development, testing, evaluation, and evolution, indefinitely.

The team should pay continuous attention to technical excellence. This is because good design enhances agility. Technical reviews with peers and non-technical reviews with users will allow corrective action to any deviations from the expected result. Aggressively seeking technical excellence will make sure that the team will be open minded and ready to adopt corrective action based on feedback.

With PHP, simplicity is paramount. Simplicity should be used as the art of maximizing the amount of work that is not done. In other words, it is essential that we prevent unwanted wasteful work, as well as rework, at all costs. PHP is a very good vehicle to achieve this.

The team members that we have should be smart and capable. If we can get those members to reflect on how to become more effective, at regular intervals, we can get the team to tune and adjust its behavior to enhance the process over time. The best architectures, requirements, and designs emerge from self-organizing teams. Therefore, for a high quality product, the formation of the team can have a direct impact.
