# Understanding the Importance of Developer Productivity

Defining and measuring programmer productivity is one of the most difficult parts of an engineering manager. There are many obstacles to maximize developer productivity, there are many standard for measuring it, Some corporations use internal metrics for measuring developer productivity and are tied to code quality, whereas others are linked to events such as product cycle. There is no all-in-one metric and the reason for this is that many challenges exist in trying to measure productivity in this context.


## What is Developer Productivity?
Productivity is a term used to measure the performance of a process where the output from continuous improvement becomes more efficient similarly Developer productivity is how productive a developer is in any given timeframe/metric. There are many metrics involved to measure developer productivity (for example, bugs fixed, code reviews done and Design Proposal made) In addition to these metrics, there are multiple ways you can measure a software developer’s productivity by using different frameworks.

## SPACE Framework
SPACE Refers to -
S: Satisfaction and well-being

P: Performance

A: Activity

C: Communication and collaboration

E: Efficiency and flow

### Satisfaction and well-being
Developers are very important for any company and their productivity gets affected by how fulfilled their work, team, and culture makes them feel.

To evaluate satisfaction and well-being, it's important to understand what matters to developers. Some of the things that can lead to satisfaction in workplace could be working on impactful projects, seeing code being used by customers, and working with colleagues that help them feel inspired.

Some key measurements include:

1. Employee Satisfaction: How satisfied developers are with their work.
2. Developer Efficacy: Access to the tools and resources needed to complete their job.
3. Burnout: Exhaustion related to work activities.

### Performance
The outcome of a developer work is developer performance. This is very difficult to measure because outcomes of both development and buisness are focussed and both of them often can’t be drawn directly back to developer output. Different factors like sales, marketing, and customer satisfaction come into play with business outcomes.
Developer Specific: quality, reliability, absence of bugs, overall service health.

### Activity
Developer activity is the count of actions performed during work. There is an easy metric to measure, but they might be more limited. For instance, it is virtually impossible to measure all the actions a developer takes in a day, and it's difficult to determine if those actions were of high quality.

### Communication and collaboration
Developers need to communicate and collaborate effectively in order to produce the highest quality productivity. Software development is inherently a creative process that requires constant feedback and ideation from colleagues. Communication and collaboration can also play a big role in overall developer satisfaction.

### Efficiency and flow
Developer efficiency and flow is a reference to how much progress a developer can make continuously without being interrupted. We’ve all either experienced or heard about “getting into a state of flow.” Getting into a flow state requires the space to consecutively do work with minimal distractions.

## Implement SPACE using Apache Devlake
A very simple and easy way to implement SPACE is by using different kinds of metrics such as :
1. Number of commits.
2. Average commit size.
3. Time to review.
4. Bug Count per 1k Lines of Code.
5. PR Coding Time.

With Devlake it is really use to get all such metrics in just few minutes, Refer to this [guide](https://shubham-2001.medium.com/launching-apache-devlake-incubating-on-an-aws-instance-1a9ada1ecc86) installation in a production ready enviroment and check all the [metrics](https://devlake.apache.org/docs/Metrics) devlake is able to provide on a dashboard using prometheus.

If we take a look at some of metrics it is really easy to understand everything and now it is possible to implement space by understanding the productivity of engineers and increase/decrease their work accordingly.

## Best Practices for Investing in Developer Productivity

### Measure Teams, Not Individuals
Even though it is really easy to measure an individual developer by looking at the following factors:

1. Number of commits.
2. Average commit size.
3. Time to review.
4. Number of code reviews.
5. Number of Design Proposals.

The most common problem a manager will face while measuring individuals is that developers cannot be measured using same metrics for everyone when we everyone has different tasks to handle. Hence a team's performance should be measured instead of each individual in the team seperately.

### Focus On Developer Experience
Developer Experience considers the developer’s journey while developing with a certain framework, language or platform. “Developer experience is the amount of friction a developer experiences between having clarity on what they want to implement and getting to the point where you have created that thing,” said Spang.

Developer Experience isn’t only relegated to public-facing platforms. Having a quality developer experience is just as crucial for internal software. The urgency to improve internal developer experience is increasing with the surge of APIs being developed, especially since the majority of them (58%) are private APIs, according to Postman’s 2022 State of API Report. Depending on the size of a company, internal DX can encompass many areas.

## Example of Quality Developer Productivity
Measure developer productivity in a multitude of ways, with some key metrics being the number of features delivered per quarter, the number of lines of code per developer per month, and the number of sprint commits. This helps engineering managers be aware of the quantity of code that is produced via the development work, be able to see if the workload of the sprint is appropriate, and be aware if there are signs of burnout from the developers.

## The Overall Benefits of Developer Productivity
An investment into developer productivity can help improve agility and developer satisfaction. For one, an easier path for development increases the velocity in how you ship and evolve projects over time. Secondly, increased developer productivity equates to more work done in less amount of time, both of which can have real business impacts.

The software development industry is growing like wildfire, bringing in waves of entry-level developers each year. Interestingly, the average experience level is decreasing, increasing the need for more abstracted tools and toolkits. In this environment, developer productivity undoubtedly plays a very important role in a startup that practice fast paced high quality development of its product to get competitive advantage over other competitors.
