AI-Powered Predictive Analytics: A New Era in Project Estimation and Planning for Software Development

ai image

Software development projects are like puzzles with countless pieces that must come together seamlessly. But one of the biggest challenges in this process is estimating and planning the project accurately. It’s a bit like trying to predict the future-a daunting task. However, with the introduction of AI-powered predictive analytics and the emergence of AI-based project management tools, a new era of software development project estimation and planning has begun.

Understand the terms

Project estimation and planning

Project estimation and planning in software development involves predicting the project’s duration, effort, and resource requirements. Project managers and teams break down the project into smaller tasks, estimate the time and effort for each task, and create a timeline. They consider factors like team size, skills, and available resources. The goal is to set realistic expectations and use resources wisely. Good estimation and planning prevent surprises, delays, and extra costs. It’s about understanding what needs to be done, how long it will take, and what resources are necessary for success.

Most of the time, the estimation process would cost the company significant money and time at the start of developing a brand-new website, app, or software.

AI-powered predictive analytics

AI algorithms can predict future events or behaviours by analyzing large amounts of data and identifying patterns. AI-powered predictive analytics in software development can estimate project timelines, identify risks, and optimize resource allocation. It enables us to make data-driven decisions and adjust plans as necessary. It’s all about using AI to predict and plan for the future based on insights from past data.

Project Estimation and Planning Before AI

Before the introduction of AI-powered predictive analytics, project estimation and planning in software development relied heavily on human expertise and historical data. Project managers and teams would analyze previous projects with similar characteristics and use their experience to estimate the effort, time, and resources required for the new project. The following are some notable challenges of traditional project estimation and planning.

Limited data insights

The amount of historical data available for analysis limited traditional methods. Estimates were frequently based on a few previous projects, which may not accurately represent the complexities of new projects.

Biases and assumptions

Estimates may be influenced by human biases and assumptions, resulting in overestimation or underestimation of effort and timelines. These biases may result from previous experiences or personal perspectives, affecting the accuracy of estimations.

Identifying risks

Another challenge was anticipating potential risks and challenges early in the planning process. Due to the lack of comprehensive data analysis capabilities, project managers relied on their intuition and experience, which may have covered only some potential risks.

Adaptability and optimization

Traditional methods lacked the flexibility to adjust estimates and plans as the project progressed. Real-time data integration was limited, preventing optimal decision-making and resource allocation based on changing project needs.

Enter: AI-Powered Predictive Analytics

The implementation of AI-powered predictive analytics has changed the process radically. By leveraging machine learning and data analysis, AI can analyze vast amounts of historical project data to identify patterns, trends, and correlations that humans might miss. Here are some of the ways AI transforms project estimation and planning:

Uncovering hidden insights

AI algorithms examine massive amounts of historical project data, detecting patterns, trends, and correlations humans may overlook. AI uncovers hidden insights that enable more accurate predictions by analyzing project variables such as scope, complexity, team size, and resource allocation.

Data-driven decision-making

Project managers and stakeholders can make data-driven decisions from the start with AI-powered predictive analytics. They gain insight into potential bottlenecks, allowing them to allocate resources better. AI provides realistic timelines, enabling stakeholders to set appropriate expectations and avoid overpromising or underdelivering.

Effective risk management

AI identifies potential risks early on by analyzing historical project data. It identifies factors that have historically resulted in delays or cost overruns. With this information, project managers can proactively mitigate risks and develop contingency plans, resulting in more efficient project execution.

Continuous improvement

AI algorithms learn from real-time project data, adapting and refining their predictions. AI provides valuable insights as projects progress, allowing teams to course-correct, make data-driven decisions, and optimize resource allocation. Over time, this iterative learning process improves estimation accuracy.

Human-AI collaboration

It is critical to understand that AI-powered predictive analytics does not replace human expertise but supplements it. Project managers and stakeholders contribute valuable experience and domain knowledge. AI provides them with new insights, enhancing their decision-making abilities.

Final thoughts

AI-powered predictive analytics has transformed software development project estimation and planning. It enables project managers and teams to make more accurate predictions, optimize resource allocation, and manage risks more proactively. We can uncover hidden insights, make data-driven decisions, and adapt plans in real time by leveraging AI’s data analysis capabilities. 

This new era of project estimation and planning combines the best of human expertise with the power of artificial intelligence, resulting in more successful and efficient software development projects. We can expect even greater accuracy and efficiency in the future as AI technology advances, paving the way for continued innovation and growth in the software development industry.

What makes up a high-quality API

high-quality API

With third-party APIs, developers can leverage the power of external expertise to enhance the functionality of their applications. However, to ensure success, they must carefully evaluate the quality of APIs before incorporating them into their applications. This chapter aims to investigate the key characteristics that make third-party APIs high-quality, according to developers.

In recent years, application programming interfaces (APIs) have become a key part of modern software development. APIs act as intermediaries that facilitate communication between different applications through established protocols and definitions. By using APIs, developers can leverage the power of other applications without needing custom integrations. In turn, this allows them to focus more on building the core parts of their applications and less on recreating features that already exist or are not feasible.

With this in mind, it is unsurprising that almost all developers (89%) report using APIs in their projects. According to our data, 74% of developers use third-party APIs while 15% state that they only use private or internal APIs. Using private/internal APIs makes it easier for developers to link their in-house applications together and ensures that only authorised personnel can access their systems and internal information. On the other hand, using third-party offerings gives them access to external expertise but introduces additional dependencies that can affect their projects.

high-quality API

74% of developers use third-party APIs

With so many developers relying on third-party APIs to expand the scope of their applications, modern services are becoming increasingly more likely to offer public APIs. However, not all APIs are created equal. Just as high-quality APIs can enhance the capabilities of a given application, adopting a low-quality API can be detrimental to its success. Implementing low-quality solutions can create a wide range of issues such as poor performance, negative user experience, and security vulnerabilities. Therefore, developers must carefully evaluate the quality of APIs before incorporating them into their applications.

In the latest edition of our global developer survey, we asked developers who use third-party APIs to identify the most important characteristics of high-quality API offerings. Our results indicate that developers consider security, documentation and sample code, reliability, ease of use, and performance to be the most important characteristics of high-quality APIs. These five qualities separate themselves from the rest as the core pillars of strength developers look for when considering third-party APIs. In fact, 89% of those who use third-party APIs mention at least one of these characteristics in association with high-quality APIs.​

Security is the most important factor in evaluating the quality of third-party APIs, according to 42% of developers. Using third-party offerings opens up a line of communication with external services that can expose their users to unauthorised access to sensitive data and other security risks. To keep up with the rapidly evolving landscape of threats, developers and modern businesses must ensure that the APIs they use are secure to protect their assets.

Developers consider security to be the most important attribute of a high-quality API

Having access to clear documentation and sample code can make it substantially easier for developers to incorporate APIs into their applications. Our data suggest that 39% of developers consider documentation and sample code to be among the most important qualities in third-party APIs.

These features allow developers to quickly understand the capabilities and limitations that a given API brings and make it easier for them to get started. This goes hand in hand with ease of use, which is mentioned by 37% of developers who use third-party APIs.

On the other end of the spectrum, reliability (38%) and performance (36%) of third-party APIs can directly impact the success of a given project. If an API proves to be unreliable, it can lead to issues ranging from minor errors to system failures and data breaches.

On the other hand, reliable APIs help developers minimise the risk of something going wrong and ensure the highest chances of success in their projects. Similarly, applications can only perform as well as the APIs they use.

Therefore, it is essential for APIs to be fast and capable of handling high volumes of requests to be used in modern applications.

high-quality API

Those who are new to the field of software development tend to work on less challenging problems and can often turn to their peers and mentors for support. As such, they are the least likely (20%) to cite documentation and sample code as an important characteristic of a high-quality API and tend to prioritise other features.

However, as they gain expertise and take on more complex projects, developers begin to appreciate the benefits that clear documentation and sample code bring to the table. In fact, 65% of developers with 16+ years of experience mention documentation and sample code among the most important characteristics of high-quality third-party APIs, surpassing even security (51%).

Highly experienced developers value API documentation and sample code significantly more than beginners

With a greater reliance on self-guided learning, experienced developers become less likely to focus on the community when evaluating the quality of third-party APIs. However, technical issues can arise regardless of experience and may be difficult to resolve or diagnose without expert-level knowledge. In turn, technical support appears to retain its above-average importance for all but the most experienced developers.

high-quality API

With more years of experience, developers gain a deeper understanding of what is essential for their projects. For some, performance may be critical, while others may focus more on ease of use. By focusing on the right characteristics of third-party APIs, developers can enhance the functionality of their applications and deliver better products.

Embedded Software Development

Embedded Software Development

Embedded software refers to computer programs designed to perform specific functions in systems or on hardware devices that are not traditionally considered personal computers. Embedded software is found in various electronic items and plays a critical role in the functioning of modern-day technology. These necessary systems are found in simpler appliances, such as thermostats and security cameras, as well as more complex systems like medical equipment, point of sale (bank card) terminals, automobiles, and aeroplanes.

Embedded software developers are traditionally one of the smallest software development groups. As of Q1 2023, we at SlashData estimate that developers self-identifying as embedded developers comprise only around 5% of developers worldwide, a proportion that has been relatively stable for the last two years. Despite embedded developers’ modest community size, they can be found across the globe, with the largest two population clusters being North America and Western Europe – with 18% of embedded software developers in each of the respective regions. The next highest regional group is the Middle East and Africa, which collectively accounts for 15%. 

Analysing data collected from more than 25,000 developers working in 160+ countries, we delve into the lives of embedded software developers. These developers are responsible for how humans interface with many critical technologies. Hence, understanding the landscape of those building and developing embedded systems can offer salient insight into industry trends and orient companies and developers alike as to where the field is heading. 

Embedded systems and data processing

In 2022 we noted an almost 100% increase in the number of embedded developers who describe data science or data analysis as a part of their role compared to 2021. In our most recent global developer survey, around a third of embedded software developers described their role as having a data science or data analysis component. 

Data processing and analysis are becoming more intertwined with embedded systems. One contributing factor is the growth in the number of Internet of Things (IoT) devices. Embedded software is an essential operating component of IoT devices, and as the number of IoT devices continues to multiply, managing, processing, and understanding the vast amounts of data accompanying this growth is a key challenge. Many embedded system developers appear to have recognised this trend and either adapted their roles or had their roles adapted for them to include this necessary data analysis and handling component. 

What are embedded developers working on, and what markets are they targeting?

In order to better understand the embedded developer landscape, we asked developers working in this field to describe the projects they had worked on in the last six months. We find that the most common embedded software project description is “network-connected”, mentioned by 41% of developers, or “internet-connected” (36%). Both categories are fundamental to IoT devices. ​

Furthermore, 35% of embedded software developers stated they had worked on projects that processed data, while 30% stated their projects involved data storage. This project reporting again highlights the importance of data management in the embedded software development field and reinforces the importance of data analysis and processing as part of an embedded developer’s tool kit. 

“23% of embedded developers have recently worked on projects that involved signal processing. They have, on average, 24% more experience compared to embedded developers working on other projects” 

Around a third of the projects embedded software developers worked on recently involved sensor or monitoring devices. Meanwhile, 23% of embedded developers have recently worked on projects that involved signal processing – audio, video, etc. As these types of technologies that interface with their local environment continue to evolve, they will increasingly shape how humans interact with devices and their surroundings.

Embedded developers working on sensors and monitoring and signal processing technologies have, on average, 24% more software development experience than embedded developers working on other projects (an average of 5.8 years vs 7.6 years). Embedded technologies that incorporate signal processing require complex algorithms that can be computationally intensive and require specialised knowledge. This increased knowledge requirement is reflected in the additional software development experience embedded developers working with these technologies have. ​

In addition to being slightly more experienced, embedded developers working on sensory projects utilise the C programming language significantly more than other embedded developers. Embedded developers working on sensory projects use the C language more than half the time, 54%, compared to 40% of other embedded developers. We believe the inflated use of C here is likely due to its efficiency and popularity in the field of signal processing data. 

Where is embedded software used?

Embedded software is utilised in an array of devices and for various applications. Hence, the markets that embedded software developers target are as diverse as the features the embedded software provides. We find that the most popular market is smart home appliances, targeted by 30% of embedded developers. As many IoT devices are increasingly sought after and can be found in the home – refrigerators, washing machines, doorbell cameras, etc. – this category’s lead aligns with our market observations. 

“30% of embedded software developers are targeting smart home appliances – where many IoT devices are traditionally found” 

Robotics comes in second place, with 24% of embedded developers reporting that they are targeting this market with their projects. The field of robotics heavily relies on embedded software to control movement, sensors, and environmental information processing – all crucial components for a robot’s functionality. As technology continues to advance, the field of robotics and embedded software will become even more intertwined in the development of intelligent systems that can be of benefit to various commercial markets such as manufacturing, transportation, and defence. 

Embedded Software Development

Embedded software developers are at the forefront of how humans interface with many technologies. With the increasing growth in the number of IoT devices, an increased number of devices will be connected to the internet and through networks and require embedded software to operate. This will necessitate embedded software developers to handle new demands in their workflow. We expect that these increasing expectations to come from both companies and consumers – such as the ability to process and analyse data and increased demand for device internet/network connectivity in IoT, respectively – will continue to push embedded developers to further broaden their skillset to be successful in keeping up with market requirements.

IoT and MQTT for Software Developers

IoT and MQTT for Software Developers

“Developers who stop learning get left behind. However, the ones that grow and expand with trends always eat well.”

– Kudzai Manditereza

The technology landscape is evolving, with the Internet of Things (IoT) leading the charge. IoT is transforming the way we live and work, with billions of devices generating massive amounts of data. As a software developer, it is essential to stay on top of this trend and understand the opportunities and challenges presented by this new technology.

In this three-part series, we will breakdown IoT,  MQTT, which is the defacto standard protocol powering IoT, and wrap the series up with a practical step-by-step demonstration you can follow to try IoT yourself. 

If we do our job right, at the end of this first article you will be inspired to dive deeper into IoT, and see how you can add it to your arsenal of skills. At minimun, you will be able to define IoT fundamentals, understand its components and the impact this has on software development. Additionally, we will explore the potential benefits and the challenges you may face when working with this technology.

Demystifying IoT: A Simple Definition (for Software Developers)

IoT can be a complex and often confusing topic, but it doesn’t have to be. At its core, IoT refers to the network of physical objects that are connected to the internet and can exchange data with one another. These objects, or “things,” can be anything from household appliances and wearables to industrial machinery and smart city infrastructure.

To understand IoT, it’s important to break it down into its components. An IoT system typically consists of three main components: sensors, connectivity, and data analytics. 

Sensors 

Sensors are crucial in IoT systems; they serve as the primary data collection points. They bridge the gap between the physical and digital worlds by converting real-world information such as temperature, humidity, and motion into digital information. Sensors enable IoT systems to monitor, measure, and respond to various parameters by detecting changes in the environment or devices.

Connectivity 

As stated, the primary goal of data collection from sensor devices is to share the data with other devices and data analytics applications in the network. Connectivity is the communication infrastructure that allows these devices and applications to communicate and exchange information, e.g, Wi-Fi or Bluetooth. 

In addition, for devices to make sense of the shared information, they must use a standard communication protocol. Examples of IoT communication protocols include HTTP(S), which most software developers already use, AMQP, CoAP, and MQTT, which has become the defacto IoT standard protocol. We discuss MQTT in detail in Part 2 of this series.

Data analytics 

Data analytics platforms, which are usually cloud-hosted, enable the transformation of typically vast amounts of data collected from sensors/devices into valuable information and actionable insights. The capabilities of Data Analytics platforms range from simple visualization for remote monitoring to identifying patterns, trends, and correlations within the collected data, and advanced machine learning-based use cases. 

Application of Internet of Things (IoT)

To give you a sense of what IoT looks like in the real world, below is a list of the use cases in the Commercial, and Industrial sectors.

  1. Smart Retail: IoT can be used to create personalized shopping experiences through digital signage, targeted promotions, and smart shelves that detect low inventory levels.
  2. Building Automation: IoT can enable commercial buildings to become “smart,” with automated lighting, heating, ventilation, and air conditioning (HVAC) systems that respond to occupancy and environmental conditions, improving occupant comfort and reducing energy costs.
  3. Smart Agriculture: IoT can be used to monitor crop conditions, soil health, and weather data, enabling farmers to make data-driven decisions about irrigation, fertilization, and pest control, ultimately increasing crop yields and reducing resource waste.
  4. Wearable Payments: IoT devices like smartwatches and fitness trackers can be integrated with payment systems, enabling users to make contactless payments without the need for physical cards or cash.
  5. Predictive Maintenance in Manufacturing:  By collecting and analyzing industrial equipment data, potential issues can be detected early, helping to prevent unexpected equipment failure, reduce downtime, and extend the lifespan of machinery.

Hardware Platforms for IoT Application Development

To start building an IoT application, you will need a device that provides a physical interface to sensors, allows you to write and deploy code to acquire data from those sensors, establish connectivity to the internet, and publish the data for analytics in the cloud.

Device platforms commonly used to develop and prototype IoT applications include Raspberry Pi, Arduino, ESP32, BeagleBone, and others. The selection of an IoT device platform is mostly influenced by each platform’s capabilities for prototyping different features or products. For example, some devices only support WiFi connectivity requiring you to plugin additional hardware for cellular connectivity. Some platforms can host a full operation system for executing multiple general-purpose tasks, while others are built to execute one specific task. 

Developing Software for IoT Applications

To develop software for IoT devices, you need to have a good understanding of the hardware and networking technologies involved in IoT. As a developer, there is a good chance you are already familiar with programming languages used in IoT development, such as C, Java, and Python. IoT solutions can be programmed using a variety of languages, depending on the specific needs of the project. Programming languages commonly used in IoT development at different levels of the technology stack include C, Python, Java, JavaScript, NodeJs, and C#:

Similar to other projects, developers should choose a language that is suitable for the hardware and software components of the IoT system, as well as the data analysis and visualization requirements.

Using Software Libraries for IoT App Development

As with any software project, leveraging software libraries can make the process significantly easier and efficient. In IoT, libraries can help manage the following:

  • Data gathering from common sensors on the market
  • Controlling common actuators such as motors
  • Communication protocols, 
  • Data processing
  • Security features

To use these libraries, developers need to first identify the appropriate ones for their project requirements, such as the protocol stack (e.g., MQTT, CoAP, Zigbee), device platform (e.g., Arduino, ESP32, Raspberry Pi), and cloud services (e.g., AWS IoT, Azure IoT, Google Cloud IoT).

Here’s an example of code in Python that might be used in an IoT system using a Python library for an MQTT Client. The code shows how to connect an IoT device to an MQTT messaging server and subscribes to receive messages of interest that are being sent to the same server by other IoT devices. 

import paho.mqtt.client as mqtt
# Set up MQTT client
client = mqtt.Client()
client.connect("broker.hivemq.com", 1883, 60)
# Define callback function to handle incoming messages
def on_message(client, userdata, message):
    print("Message received: " + message.payload.decode())
# Subscribe to topic
client.subscribe("iot/devices/sensor1")
# Start the MQTT client loop
client.loop_start()
# Continuously listen for incoming messages
while True:
    pass

As previously mentioned, developers can create IoT applications able to interact with physical devices, gather data from sensors, and even automate tasks. IoT development involves a combination of software development, hardware design, and networking, so developers need to be well-versed in all these areas to create effective IoT applications.

IoT Software Development: Similar But Different

 The software for IoT differs from traditional software in several ways:

  1. Resource constraints: IoT devices often have limited computing power, memory, and storage compared to traditional computing devices. As a result, IoT software must be designed to use resources efficiently and effectively.
  2. Real-time requirements: Many IoT applications have real-time requirements, meaning that data must be processed and analyzed quickly, often in milliseconds or less. This requires a different approach to software design and development.
  3. Distributed nature: IoT systems often involve many interconnected devices that must work together to accomplish a task. This requires a distributed system architecture and a focus on communication and coordination between devices.
  4. Security: IoT devices connect the internet to the physical world, and security breaches can have life-threatening consequences. Therefore, IoT software must be designed with security in mind, including data encryption, access control, and secure communication protocols.
  5. Heterogeneous environment: IoT devices can run on a variety of hardware and software platforms, which can make software development and deployment more complex. Developers must be able to work with a wide range of platforms and technologies.

Understanding these differences, as well as IoT components, allows you to leverage each of their powers and create innovative and impactful applications that improve people’s lives and transform entire industries.

An example of a possible career path in IoT is IoT Engineer.  An IoT engineer is a professional who specializes in designing, developing, and maintaining Internet of Things (IoT) systems. They are responsible for creating the software and hardware components of IoT systems and ensuring that they work together seamlessly to achieve the desired results.

Conclusion
