Why are agile methodologies key in software development?

Agile methodologies are some of our favorites, as they are the working models we use at Nuvolar to develop our solutions. Thanks to these frameworks, we can develop high-quality applications faster and with more convenient technical methods. Partly, this is because these procedural frameworks prioritize partial deliveries of the developments, allowing their elaboration through iterative cycles. In this way, continuous feedback helps to improve the application and adapt it to the needs of the client and end users.

Software development before agile methodologies

Before the emergence of agile methodologies in 2001, the software development process required a large amount of documentation. This documentation also had to be available before the start of code programming. Often, the technology business analyst would write a document with the requirements and functionality that the customer needed from the application. These business requirements briefings were very extensive and included all the details of the project.

Based on this document, the developers prepared their own technical requirements document. In this report, they defined the application architecture, data structures, object-oriented functional designs, and user interfaces, in addition to other non-functional requirements. This development process — known as waterflow — continued with the coding process. This step was followed by integration and finally testing. The whole sequence could take up to two years before bringing the application to the production phase.

As you can see, this method was not flexible at all. The introduction of changes during the development of the application was complicated and delayed the delivery time. Consequently, when many of these developments were presented to the customer or released to the public, they were already obsolete. The needs of the company and the users could change in two years.

What are agile methodologies and what are their main characteristics?

All this changed in 2001. During this year, a group of renowned software developers found commonalities in the alternative work methodologies to waterflow that they were using. Among the members of this group were Ron Jeffries, Ken Schwaber, Martin Fowler, Kent Beck, and Jeff Sutherland. Together they wrote the Agile Manifesto, a document that brought together their shared proposals on how a contemporary software development process should be structured. To summarize, three of their main premises were:

  • To rely on collaboration over documentation.
  • To privilege organization within the team, rather than rigid management practices.
  • To promote the ability to manage change rather than accept the rigor of waterfall development.

What do these methodologies consist of?

We can define agile methodologies as evolutionary methods based on timely and iterative processes for software development.

In summary, these methods are characterized by:

  • Focus on collaborative development. Users and stakeholders actively participate in the evolution of the product together.
  • Minimize unnecessary work and excessive documentation. The less time spent on paperwork, the more time that is available to spend creating the application.
  • Accept that uncertainty is an intrinsic part of software development and that it is difficult to control changes.

In Agile methodology, work teams are multidisciplinary and composed of diverse professionals. They all possess the necessary skills to execute the work.

Considering that the goal is to develop a working technology solution, the team must ensure the correct functioning of the applications from start to finish. With this goal in mind, the database, business logic, and user interface of the application are developed and demonstrated in parts. In other words, it is not necessary to wait until the entire software is finished to test and present it. To this end, team members must collaborate and frequently meet to ensure that everyone is aligned with the objectives. It also helps l to verify what everyone is doing and how the product is developing.

We can summarize the advantages of these methodologies as follows:

  • Greater capacity for rapid response and adaptation to change.
  • No excess of formal processes.
  • Constant communication between project team members.
  • The client receives information on the development of the project throughout the process.

How do agile methodologies influence software development?

Implementing an agile procedural framework with the principles and characteristics above results in higher quality applications in less time. It’s also worth mentioning that it allows the use of more suitable technical methods in the development of tools. The methodologies we are discussing emphasize adaptability and flexibility. Therefore, there is no up-front definition of answers, as with the waterfall scheme. Instead, the problem is broken down into rapidly developable modules to test with users.

Under these conditions, it is easy to check if something is wrong or if any details are missing It is also immediately possible to adapt the effort to reinstate the original approach or change it if necessary. In the agile approach, each team member contributes to the solution and takes personal responsibility for their work.

Today, agile methodologies are adaptable to web and application development for almost all purposes. Moreover, agile development frameworks and processes prioritize the delivery of software solutions iteratively and encourage feedback. This ensures that teams tailor applications to users’ needs and expectations.

Another favorable consequence of agile development is that it facilitates a process of continuous improvement. Indeed, the solutions developed require constant updating of their functionalities and support. Therefore, the iterative nature of these methodologies helps to establish a culture of continuous improvement.

What are the most commonly used agile methodologies?

There are many agile methodologies practiced for software development. Each of them allows different levels of flexibility during the process. Below, we will briefly mention some of the most commonly used ones:

Scrum

Scrum is a model suitable for projects whose requirements are constantly changing. It consists of delivery cycles called sprints and structured meetings to:

  • Plan the sprint and establish sprint priorities.
  • Engage the team by reviewing a list or backlog of user stories which helps to define the amount of work for the sprint.
  • Update the development status of the sprint.

The sprints culminate with a meeting demonstrating the functionality of the product to the customer. This demonstration is followed by a retrospective team meeting to discuss achievements and improvement requirements.

Extreme Programming Model (XP)

The success of the Extreme Programming Model (XP) methodology depends largely on the team’s technical expertise and commitment to collaboration. In short, it consists of developing several small versions of the application. This reduces the costs generated by changes in requirements. The work dynamic involves pairs of developers who execute a simple design and whose code is continuously improved by considering user feedback.

At Nuvolar, we use the Lean methodology.

Lastly, we will discuss the Lean methodology. This is the methodology we use at Nuvolar to approach application development for our customers. This scheme of work focuses on creating highly usable and easily manageable software for users. It includes the most beneficial and necessary functionalities according to the purpose of the solution. With this objective in mind, we propose short iterations to design, build, test, and analyze a prototype with minimum requirements.

At the end of each iteration, we present partial deliverables to the client. Then, we restart the process to incorporate new requirements and make improvements, if necessary. The idea is to avoid wasting time and resources. This also allows us to perform customized and quality development within the agreed deadline.

At Nuvolar, we can do it all! We have a great team of multidisciplinary professionals who understand your needs and those of the users of your applications. We are experts in custom software design and development, and highly-experienced in working with UX and UI design criteria.

5 benefits and challenges of transitioning from Developer to Product Owner (PO)

5 benefits and challenges of transitioning from Developer to Product Owner (PO)

by Daniele Baldon

When I first heard about the Product Owner (PO) role, I thought it was not for me. I was a developer on a mission to code and create a product that solved any technical problem, while the PO was the person trying to fit as many tasks as possible into the plan!

However, I took on the role of PO just a few months ago after being a Java developer for seven years. If you are a developer, you are probably asking, “Why did you do that?” The answer is simple: for natural tendency. I was always heading towards this change, even if I didn’t realise it at the beginning. For example, my focus was already more on the product than the mere code itself. Therefore, I saw the PO role as one where I could capitalise on my soft skills more than my development skills. Moreover, I was growing fond of the new product that our team was developing at the time, so I wanted to be more involved in the decision-making process in both the short and long-term lifespan of the product.

The first months of the transition were neither easy nor hard. It was, and still is, rather complex. My daily life changed completely. For example, as a developer, a feature lifespan involves thinking about HOW to implement it, develop it, and solve merge conflicts. As a PO, however, the lifespan of a feature starts much before its birth. The client needs are translated into requirements that help to define WHAT will be the new product feature. It has to be analysed, estimated, and prioritised. It is also necessary to explain extremely well to the development team WHY the feature is needed. Once it is implemented, it needs to be validated against user expectations, and it will likely need a second iteration.

During the transition, I realised that having a developer background was an advantage for me. Let me share the five main ways that having a development background helped me, and the five main changes I had to embrace. If you are a developer wondering if the PO role is for you, I hope it helps you weigh your decision.

Benefits of having a development background

  1. You know the inside of the product. You understand how it works internally, as well as all of the strengths and the weaknesses. This is especially helpful with a backend project with no outside visibility of what is being implemented. For example, if the product is an API, with visibility on the json requests and responses only, then the product decisions are tight with the technical solutions. Having a technical background can help you drive possible feature discussions with clients towards a more favorable terrain.
  2. You’re able to provide a fairer approach to technical tasks. For example, code refactors, which are often marked as a low priority since they offer nothing visible to the user. How often do we hear about how the technical debt of the project hinders implementations, causes trouble, or non reproducible bugs? And then in the plan, there is barely space for those tasks?
  3. Developer gibberish or “tech speak” actually makes sense, and you’re able to understand its implications for the tasks, projects, and planning!
  4. You can help make sure development discussions are thorough and that all details are discussed. You can help guide conversations with development teams with the finest grain of detail. Suppose a developer complains that a task is technically impossible to implement or it has drawbacks that you did not consider. In that case, you can understand the reasons behind them and help to find possible alternatives which still meet the same business requirements.
  5. Your project plan tends to have a bigger buffer, especially for the most technical functionalities, and, therefore, is more realistic. Integration tests, refactors, spikes, and unforeseen technical problems are left out of the plan too often. For example, while implementing a frontend button could take a known standard amount of time, what is the standard for a new CI/CD system? Or for setting up a Kubernetes cluster? There are systems that are very hard to VROM and plan; however, being aware of the complexity of the work can be an advantage in order to not underestimate them.

The changes to embrace

  1. Your responsibility now involves what needs to be implemented, not how. Even if you don’t want to close IntelliJ or Eclipse, which has opened up on your screen by default for so many years, you’re going to realise you don’t have time for both POing and coding. Therefore, you must detach from the code. You cannot control everything. Perhaps you can do some Code Reviews at the beginning if you wish, but soon, the code probably will have changed so much that your code review will not be exhaustive anymore.
  2. Think about your new responsibilities. Are they clear? It may seem like a simple question, but if you have a simple answer, then it is probably not the whole truth. It is important to define clear responsibility between you and the development team. In the beginning, you’ll probably want to participate in technical decisions. “I know the code!” you might think. Sure, for the first month or so, you might; however, code is changing every day, and you cannot control it! Moreover, you have a fantastic development team, so leave the technical decisions for them. It is not up to you anymore to discuss if a strategy pattern is the most appropriate implementation. Remember when you were complaining about POs trying to define database columns names?… Right?!
  3. The decisions are more complex. One of the main changes of mindset I’m still embracing is with the decision drivers. When coding, if the acceptance criteria are well specified, then the final result can only be right or wrong. The unit tests are either green or red. The QA either passes or not. As a PO, answers are never 100% right or 100% wrong, black or white. It’s always a nuance. Experience can help, but experience is precisely what you will lack the most of in the first months! So what should help to drive your decisions are data and user feedback. User feedback is not always easy or fast to get, and sometimes decisions must be taken quickly. Data, instead, might be easier to get. But where is the data coming from? You and your company are likely to have access to tons of data already that no one paid attention to until now. Jira generates lots of data, for example, and there are plugins that help you to interpret them. The product itself can generate the data you might need. And I’m sure the development team would be more than happy to add a microbenchmark or a monitoring or logging system.
  4. Start speaking in business terms, not technical terms. It is not as easy as it might sound, especially if you are used to talking about the same topic with the same team members and just from a different perspective. However, it is very important. When you explain a task from the technical point of view, you focus on the how-to and the details, taking for granted that you already understand what needs to be done. Meanwhile, when you explain a task from a business perspective, you are helping the developers understand what the task is about and why, regardless of the details. There are always several ways to implement the same business feature, while there is usually only one technical solution that solves one specific problem. Focus on the acceptance criteria, on extraordinary cases, how the user will use a feature and why, and try to pass down information the best you can to the development team.
  5. Different achievements. One of the feelings I initially missed the most in my new role was the sense of completion. As a developer, once a task is done, you forget about it and go take on the next one. Once the QA has passed, you could be proud of your implementation. But what is the definition of DONE for a PO? Once the product is in production? Once a new feature receives positive feedback? In my opinion, such a question does not apply to a Product Owner. Instead, you must enjoy every day, every discussion, and every decision. There are no definitions of DONE, and no concept of finish. Once a feature is done, it might need to be modified. And once the product is in production, it is already time to improve it, since in the IT business everything changes fast.

Change is the only thing that is permanent, so enjoy the changes!

Cloud migration: ideas and recommendations for success

Cloud migration: ideas and recommendations for success

Cloud migration is a practice that is becoming increasingly common in the corporate world. Thanks to its many advantages, a lot of companies are taking the leap and hosting their operations in the cloud. You may have some questions about this term. For example, what exactly is cloud migration, what are the benefits, what is the process, and how can you perform a cloud migration successfully? We’ll answer all of these questions below.

What is cloud migration?

When we talk about cloud migration, we are discussing the process of moving the digital aspects of a company to the cloud; that is, making services, applications, and operations work on remote servers with online access. Obviously, this involves a large amount of resources, such as storage, data processing, and application execution.

Once cloud migration is complete, it means that IT processes are no longer performed on-premises. Rather, they are managed remotely. This, in most cases, represents an improvement in performance and efficiency of several departments in an organization. In other words, it is the direct result of reducing the efforts required to maintain, update, or upgrade one’s own data center.

In short, cloud migration is the transfer of the digital infrastructure within a company from local to remote or the cloud. This term can also refer to the migration between two cloud services; however, the most generalized meaning is the first one.

The phases of cloud migration

Migrating to cloud services is a process with several phases. Below we analyze what they are and what is important to take into account during each of them.

Cloud Migration Requires IT Replication

The first step in cloud migration is to replicate the local IT infrastructure in the cloud. Although it may seem possible to complete this phase quickly, its complexity sometimes prevents that from happening. In fact, IT replication can take years to complete, especially for large enterprises. The most common approach is to migrate the entire corporate infrastructure gradually. However, it’s recommended to establish a timeline so that you start to see the benefits of the migration as soon as possible.

Time to rebuild and automate

The main objective in the second stage of cloud migration is rebuilding and automating processes. This step is essential for cost savings. Developers tend to use too many resources at the beginning of the cloud migration process which, of course, comes at a cost to the company. But as they gain experience and become better adapted to cloud systems, they are able to automate resources and deactivate them when they are no longer needed.

Cloud migration and containers

At this point, the use of containers, such as Docker or Kubernetes, becomes essential. These containers are able to manage workloads and services more efficiently. In addition, they provide automation tools. Many of the containers are relatively easy to extend, which facilitates the scalability of cloud services.

Minimizing the impact on servers with serverless applications

Finally, once the previous steps are complete, it is time to reduce dependency on servers. How? By designing serverless applications, which reduce dependence on containers. This is also known as Functions as a Service or FaaS.

What are the advantages of cloud migration?

Migrating a company to the cloud is not an easy task. However, there are many advantages. Understanding these benefits is the best way to remove any possible doubts prior to cloud migration.

  • Minimal maintenance. The cloud eliminates many of the IT department’s responsibilities. In fact, it’s possible to outsource most tasks to the provider, who maintains responsibility. As a result, there is a significant reduction in maintenance costs. .
  • The cloud provides flexibility. Expanding or reducing services in the cloud is much easier. Since additional resources almost instantaneously, companies can deal with peaks in demand or launch in new markets more quickly.
  • Increased security. Companies that want to offer reliability to their customers and employees must have powerful protection systems in place. By migrating to the cloud, this responsibility is shared between the users and the provider, with the latter providing its customers with powerful security systems.
  • Cloud migration promotes mobility. Cloud applications are the starting point for telework. Because they are always available and accessible from any device, an employee can attend to his or her responsibilities regardless of time or place.
  • Reduced costs. All of the advantages above lead to cost savings. Thanks to cloud models, corporations can be more efficient, faster, and more versatile with less investment.

There are many strengths of cloud migration. If you’re ready to get started, here are some important recommendations to make your leap to the cloud a success.

Recommendations to make your cloud migration a success

Although the advantages of cloud migration are diverse and appealing, it can be a painstaking process. However, we have a few ways to help make your migration to the cloud a success.

Design a pre-strategy

Before making the leap to the cloud, it is important to plan the entire cloud migration process. First, it is very important to establish your objectives, deadlines, and identify your specific needs.

Evaluate the offers of different suppliers

Analyzing the different offers currently on the market will help you avoid unnecessary cost overruns. In addition, you will be able to check if each provider offers what your business needs. Getting this right is much easier if you already have a good cloud migration strategy in place.

Examine the terms of the contract carefully

Before contracting a service, you should know what clauses are included in the contract. This will allow you to understand in advance the responsibilities and obligations of each party. In addition, you should not forget that the contract should reflect compliance with other legal provisions, such as data protection regulations, in the area where your company operates.

Take advantage to optimize your company

The cloud migration process has its challenges. After all, getting everything to work together seamlessly is a long and complex journey. However, it could also be a good time to change the way you do things. If your current infrastructure has problems, migrating to the cloud may be the perfect opportunity to solve them.

Remember to consult a professional

The last recommendation we can give you is to seek expert support. In the long run, getting tailored advice will help you minimize errors in the process and waste fewer resources. It is very clear that cloud migration is a trend that is slowly taking hold. But it can be a major task and to complete it successfully it is essential to have the best professionals helping you.

At Nuvolar, we can help make your cloud migration a success.

How cloud solutions contribute to business growth

How cloud solutions contribute to business growth

How companies grow depends heavily on their use of technology. The clear trend in the business world is towards cloud solutions. With cloud solutions, companies gain many advantages, such as the ability to optimize resources and work more efficiently. How else can cloud computing help companies grow?

In this article, we will analyze some of the main advantages that new cloud technologies are bringing to large and small organizations. But first, let us tell you exactly what we mean when we talk about cloud solutions.

What are cloud solutions, and what are they for?

The cloud is a concept that involves migrating multiple computing resources to external servers and processing units. A cloud solution provides users with access to services, applications, and platforms through an Internet connection.

This type of resource outsourcing can be applied in very diverse fields. A common one is data storage. It is increasingly common to save files on remote devices, either in a private or public cloud. Keeping documents on a remote devices facilitates employee collaboration and reduces investment in personal equipment. Of course, it also increases security by preventing accidental loss of information.

Another area where cloud solutions are booming is software. Just a few years ago, companies had to spend a lot of resources on keeping their employees’ applications up to date at each workstation. With the implementation of cloud solutions, software updates can take place remotely, delivering new features constantly and immediately. Again, this favors the growth of companies by allowing resources, both human and material, to be better utilized.

It is clear that cloud solutions are becoming increasingly important in the business landscape. But how do they really help companies grow?

Cloud and business growth: two increasingly linked concepts

The cloud model helps companies grow in many different ways. Let’s take a look at a few examples of the benefits of cloud solutions.

Business growth depends on collaboration

One of the strengths of the cloud is its ability to centralize files in one place. Historically, achieving universal access by workers within a company was possible with network drives or servers. In this type of infrastructure, ongoing maintenance is vital to avoid errors and data loss. Scalability is also extremely difficult as it requires continuous investment to purchase new equipment and increase storage.

All of these inconveniences can be obstacles to a company’s growth. But with the advent of cloud solutions, all employees have space to save their files and can easily access shared files. If a company needs more storage space, then it simply has to add it. The provider is responsible for maintaining the servers and providing protection in the event of unintentional loss of data and information.

In short, the company no longer has to worry about the storage infrastructure. It simply has to focus on managing its files and keeping them organized.

Flexibility to scale up or down

Another advantage of cloud solutions that helps companies grow is scalability. Peaks of activity are common for many companies, whether it’s increased demand for their services or new projects. It is possible that, during a period of increased work, the company needs specific resources, applications, or services. Then this need disappears after completing the work.

In these situations, cloud solutions play a key role. If the company needs specific software or to increase its storage quota, then it can purchase it temporarily. As soon as it is no longer needed, the business can simply reduce its subscription. This flexibility eliminates license purchases, hardware investments, and other expenses. In addition, it is possible to expand the company’s capacities in just a few clicks and across the board for all users, if necessary.

Telework is a reality

In times of crisis, teleworking can become a company’s lifeline. Employees can continue their work from anywhere, whether at home, in the office, or traveling. Teleworking has undoubtedly helped companies grow even in the most challenging situations.

With a growing number of cloud services, more companies can offer teleworking options to their employees. For example, a company can contract a number of cloud services, such as spreadsheet managers or document processors, cloud storage, invoicing systems, etc. to facilitate remote work. All of these cloud-based services can be scaled up or down as needed and many provide constant updates to keep up with the latest business needs.

It’s important to keep in mind that the cloud model not only allows the execution of third-party applications over the Internet. It also tolerates the creation of customized software for individual companies, all hosted remotely. This greatly facilitates usage on any device, regardless of its operating system. As a result, it is possible to meet any organizational or logistical needs, provide universal access to the company’s tools, and update them simultaneously on all of the organization’s device.

Ultimately, whether a company relies on third-party services and software or designs its own, doing so in the cloud favors teleworking. Moreover, it minimizes costs and allows organizations to implement improvements quickly.

Businesses now only need a web browser

Lastly, cloud solutions increase business growth by removing some critical barriers. First, specific hardware specifications are no longer required to run certain programs. Since all data processing is done remotely, cloud-based applications have much lower minimum specifications. This results in better performance, even on modest devices. Consequently, the company will not have to make significant investments to keep its employees’ equipment or workstations up to date.

Secondly, there is no need to install anything. Most cloud-based applications and services are accessible from a web browser. Thus, a single software provides access to an infinite number of resources that only require Internet access. Most of today’s web browsers are automatically updated, solving security issues on their own.

Are cloud solutions really the future of business growth?

Undoubtedly, they are. In this article, we have discussed the different cases in which cloud solutions play an important role in promoting business growth. Although not all organizations have the same needs, cloud solutions can adapt to almost any circumstance thanks to their flexibility.
