9 books on the software development life cycle (SDLC) you need to read

Posted on December 29th, 2022

The software development life cycle, also known as the software development process or SDLC, comprises the processes and activities required to develop, maintain, and support software throughout its life span. Ranging from ad hoc to extremely formal, SDLCs can vary from company to company, depending on a wide range of factors. 

However, no matter the methodology or framework used, one thing is certain: SDLC is becoming increasingly complex. Software development is no longer a linear process – it’s become a fast-evolving collaborative process by teams that are often spread across several geos and time zones. 

With the advent of agile software development approaches, the importance of understanding and following the software development life cycle has never been greater. We’ve put together a list of 9 books that will help you a clear understanding of SLDC and its different processes and approaches.

How to use KPIs to measure software development productivity

Posted on December 21st, 2022

There are lots of reasons to measure the productivity of your R&D team, including understanding the overall level of the team’s performance, developing benchmarks, tracking progress, identifying high and low performers, improving processes and operations, justifying your investments, and determining resource allocation. 

But if you’ve ever attempted to measure your software team’s productivity, you’ve probably run across several snags in the process – from trying to define what productivity actually means, to attempt to identify the metrics that reflect that definition. 

This post discusses the various challenges involved in measuring dev productivity and offers a KPI strategy to help you really understand the performance of your R&D teams. 

Defining software engineering productivity

Before you can even start to measure productivity, you need to define it. Usually, productivity is defined in terms of inputs and outputs, where you divide your output by your input to get your ROI. Using this method, we could, theoretically, measure the input and output of a software developer as follows:

Input:

  • Salary
  • Amount of hours worked

Output:

  • Software features
  • Documentation
  • Deployments
  • Bug fixes
  • PRs

It’s easy to see the problem, since it’s so difficult to measure the outputs themselves. Good measurements of output should have a strong correlation with revenue. However, if we break down the metrics for measuring those outputs, the correlation tends to be pretty weak. 

For example, one common metric for measuring developer productivity is lines of code (LOC). The thing is, for several reasons, more isn’t always better. For example:

  • Developer A might write significantly more lines of code than Developer B, but is it good code? Will Developer A’s code introduce more bugs to the system than Developer B’s? 
  • The more code you have, the more resources you need to maintain it
  • Developer A might be less skilled than Developer B, and could be assigned to less challenging features that have lower customer value

Further, the difference between physical lines of code and logical lines of code adds to the complexity involved in measuring LOC. 

Considering the flaws inherent in defining software development productivity using inputs and outputs, it makes more sense to define it as a measurement of your team’s ability to quickly and efficiently create useful, good-quality software that’s easy to maintain and has high customer value. 

Now that we’ve defined dev team productivity, we can try to figure out how to measure it. 

Identifying the right KPIs

The reality is, there’s no one metric that can be used to assess productivity, since each KPI, on its own, lacks important context. We’ve already discussed some of the problems inherent in measuring lines of code, but there are similar issues involved in all commonly used productivity metrics:

  • Code-based metrics

    In addition to lines of code, other code-based metrics include commits, pull requests, code review turnaround time, code churn (also referred to as “rework), code coverage, closed change requests, and bug fixes. While all of these metrics are possible indicators of productivity, the same issues apply: They’re all missing important context and can be gamed in a variety of ways that almost always sacrifice quality.

  • Velocity

    Velocity measures the amount of work your team can complete during an average sprint. The team assigns points to each story (based on estimated complexity, risk, and repetition), then calculates the average amount of points achieved each sprint over a period of time (minimum 5 sprints). This is one way to track your team’s overall progress and figure out how realistic your team’s goals are.
    However, if we look at how we’ve defined productivity, it’s easy to see how quality can be sacrificed to maintain or improve velocity. Cognitive bias can also play a part by inflating the amount of points assigned to each story.

  • Function points

    Function points are units that measure the functionalities that a software service or product delivers to its end users, meaning what the software can do in terms of tasks and services. The advantage of function points is they are relatively agnostic to the technology model as well as the dev model used. These points are assigned using the Function Point Analysis (FPA) rules, which include 5 components: external inputs (EI), external outputs (EO), inquiries (EQ), internal logic file (ILF), and external logic file (ELF). However, since the assignment of function points is made by the team, they’re subjective and can be manipulated.

  • Pull requests

    Pull request metrics, such as time to merge, lead time, size, flow ration, and discussions, have increased in popularity recently as a way to measure development productivity. However, tracking these metrics doesn’t factor in the effort or impact of the work performed. It can also be unfair to developers who are working on a legacy codebase, compared to developers working on a greenfield project.

  • Sprint burndown chart

    This is a graphic representation of how much work has been completed during a sprint and the total amount of work remaining in the sprint. While good for identifying issues such as scope creep and oversaturation of features, it lacks several important factors as well as the context needed to get the full picture.

  • Evaluations

    Both manager and peer evaluations are a good way to give real context to the performance of your team, however, they are highly subjective and can be subject to abuse or bias.

Combining weighted KPIs to measure your team’s productivity

Every company and development team is different, with its own set of dynamics and processes. Using a combination of the above metrics, then weighting them (and fine-tuning the weighting over time) in terms of their importance to your team and company leadership, is a good way to measure your team’s overall performance, dynamics, and the efficiency of your processes. 

For example, you create a set of criteria, such as correlation with revenue, continuous delivery, high quality, function to user, team cooperation, objectiveness, etc. 

Then score each metric on a scale of 1-5, based on how well that metric meets the above criteria. For example, you might give Pull Request metrics a high score for team cooperation, but a low score for correlation with revenue. While functionality points could score high for revenue correlation, they might score low for objectiveness. 

Once scored, you can weigh these KPIs using the scores, in order to reach a final productivity score that more accurately reflects your team’s performance. In addition, multiple metrics are less subject to abuse and bias than any single metric. 

It’s also important to measure the entire team vs. each individual member, since the true scope of software team productivity is far larger than any one developer on your team. 

Yes, each team member’s success has real value, but since we’re trying to increase the creation of useful, high-quality, easy-to-maintain software, many more factors must be taken into account in order to get a real understanding of your team’s productivity.

Summary

Since single KPIs can be misleading when measuring software engineering productivity, we recommend using a combination of weighted KPIs, which can offer more in-depth and nuanced insights into your software team’s performance.

The rise of generative AI: How it’s transforming industries and unlocking new opportunities

Posted on December 7th, 2022

One of the key benefits of generative AI is its ability to create new content that is diverse and unique. Unlike traditional AI models, which are limited to the data they are trained on, generative AI can explore a wider range of possibilities and produce outputs that may be surprising or unexpected. This allows it to generate content that is more creative and engaging than what is possible with traditional AI techniques.

One way that generative AI is being used today is in the field of natural language processing (NLP). NLP is the study of how computers can understand, interpret, and generate human language. With generative AI, it is possible to create models that can generate new sentences and paragraphs that are coherent, grammatically correct, and even engaging. For example, ChatGPT is a generative AI model trained on a large corpus of text data that can be used to generate human-like responses in a chatbot.

Another area where generative AI is making an impact is in the field of code generation. Tools like Tabnine use generative AI to automatically suggest code completions, making it easier and faster for developers to write code. By training a generative AI model on a large dataset of code, it is able to generate new, syntactically correct code that can be used to speed up the development process.

As an example of the quality of generative AI, this blog post was written by a generative AI model trained on a large dataset of text. The model was able to understand the topic and generate a coherent and engaging article, demonstrating its ability to create unique and original content.

Overall, generative AI is a powerful and versatile tool that is making an impact in a variety of fields. By enabling computers to generate new content, it has the potential to unlock new possibilities and create new opportunities for creativity and innovation.In addition to the applications of generative AI mentioned in the previous paragraphs, there are many other tools and systems that use generative AI to make our lives easier and better. For example, Tabnine is a code-completion tool that uses generative AI to automatically suggest whole lines and full function code completions, making it faster and easier for developers to write code. This can save a lot of time and effort, and can even help prevent errors and bugs in the code.

Tabnine also offers a secure and private Enterprise solution, with options for self hosting, making it suitable for use in sensitive environments such as financial institutions or government agencies. This allows organizations to take advantage of the benefits of generative AI without sacrificing security or privacy.

Overall, generative AI is a powerful and versatile tool that is making an impact in many different areas of our lives. Whether it’s making it easier to write code, creating new images, or generating unique and engaging content, generative AI is helping us to unlock new possibilities and create new opportunities.

Top 5 challenges generative AI faces

Here are the top five challenges that generative AI systems face:

Data scarcity: One of the biggest challenges facing generative AI systems is the lack of large, high-quality training datasets. These systems require a large amount of data to learn from and generate new content, but it can be difficult to find and annotate large datasets.

Mode collapse: Another challenge is mode collapse, which is when a generative AI system only generates a limited number of outputs, rather than a diverse range of outputs. This can lead to repetitive or low-quality outputs.

Bias and fairness: Like any AI system, generative AI systems can be susceptible to bias and unfairness. For example, if the training data is biased, the generated content may also be biased. Ensuring that generative AI systems are fair and unbiased is an ongoing challenge.

Control and interpretability: Generative AI systems can produce surprising and unexpected results, which can be difficult to control and interpret. This can be a challenge when using these systems in sensitive or regulated industries, such as healthcare or finance.

Adversarial attacks: Finally, generative AI systems are vulnerable to adversarial attacks, where an attacker tries to trick the system into generating incorrect or malicious outputs. Defending against these attacks is a significant challenge for generative AI systems.
