Change Management in IT projects

In the world of IT, almost everyone is involved with projects, directly or indirectly. While there are several standardised project methods, the human element behind the projects is neglected and normally does not play a bigger role, even though it significantly impacts the project's success or failure.

Project Landscape and Focus

Top Management but also Project Leaders often lack adequate insight into the changes a project will bring. Top Management is occupied mostly focusing on ensuring the strategic plans are executed. Project Leaders on the other hand focus mainly on deliverables and timelines. 

And what about addressing human dynamics?

The projects introduce societal and technological changes, and everything is done at a fast pace. Those changes impact people, and prioritising the human aspect must be done, mostly by learning from individuals' experiences in the "project universe".


Features vs Feelings

Projects often focus on delivering technical features, on the other side failing to address the human side of changes to be implemented.

Change Management needs to ensure that the functional features implemented are also embraced by users.



Good Practices doing Change Management

The employees (and generally all stakeholders, especially i.e. end users) should be involved already from the earliest stages of projects. By "involving" it is not only meant to explain what is going to be done, but much more to listen to them, hear their concerns, and address the resistance. So the Change Management needs to be started alongside project initiation, to enable the organisation integration to happen seamlessly with technical implementation.

To ensure smooth organisational transitions, the projects must not just be implemented but also adopted.


Do not Overload the Organisation

Oftentimes the top management's focus is much more on identifying what projects need to be launched to implement the company strategy, and the organisation's "project capacity" is forgotten. Launching too many projects simultaneously can overwhelm teams, leading to reduced benefits, sometimes even to project failures. Maintaining a manageable strategic pacing is crucial for both organisational health and project success.


Change Leaders' Mission, Core Qualities and Tools

To be successful as a Change Leader, those are the main focus points:

  • Ensure the top management's support;
  • Involvement, having the focus on a human-centred approach, prioritising the people impacted by the projects;
  • Communication needs to be strong, clear, timely and effective;
  • Collaboration with Project Leaders, and while they focus on execution, Change Leaders address the human and organisational challenges, thus aligning technical and emotional dimensions;
  • Heatmaps help identify those departments most affected by projects, ensuring balanced workloads and readiness for change, avoiding overloading;
  • Choosing and using one of the Change Management methods, like the ADKAR model (Awareness, Desire, Knowledge, Ability, Reinforcement) helps analyse and address resistance, and foster engagement.

Future of Change Management

The top management is increasingly recognising Change Management's significance for long-term success, and it’s evolving into a broader organisational role beyond individual projects.
Its importance will also grow as a result of continuous technological advancement, which is happening at an increasingly quicker pace.
To ensure sustainable growth, organisations must integrate change leadership into the core strategies.

Why use Pascal programming language?

Why would anyone want to use Pascal, a programming language designed decades ago?

Some might be surprised that Pascal is still "alive" today, and does not belong to some IT museum.


Let us try to see what Pascal can be used for nowadays.


Educators and students

Pascal is used by both educators and students.

Learning programming fundamentals

Pascal is, in fact, an excellent choice for learning fundamental programming concepts, as it encourages good programming practices using structured programming and data structuring.

Math

There is a rumour that mathematicians like to use Pascal. Why? Well, first of all, remember that it was named after the French mathematician, philosopher and physicist Blaise Pascal. ☺

Also, it might be because of its correctness in terms of how it is written.
Mathematicians hate to see expressions like a=a+1 ❌ in some other programming languages, simply because a is not equal to a+1 in mathematics. 
In Pascal, one writes a:=a+1 ✅ which is not a mathematical expression, thus acceptable.
One can correctly use the equation symbol in Pascal, i.e. in the "if" statement: if a = 3 which is fully acceptable by mathematicians. ☺

OOP

Pascal was originally a procedural language, but what about Object-Oriented Programming? 

The more modern variants like Object Pascal, Free Pascal, and Delphi support OOP.


Cross-Platform Compatibility

Pascal compilers are available for various platforms/operating systems: Windows, OS-X and Linux.


Efficiency and Performance

Pascal is not an interpreted but a compiled language. The code is first compiled, then linked, and then executed:

Target OS: Linux for x86-64

Compiling main.p

Linking main

26 lines compiled, 2.8 sec

The code generated by Pascal compilers is highly efficient, making it a good choice for performance-critical applications.


Embedded systems

Pascal's compiled nature and strong type system contribute to the development of efficient and reliable embedded systems.


Legacy Systems

Many systems were developed with Pascal or related programming languages in the 1980s and 90s. Many of those systems still need to be operational, i.e., in industries like banking and manufacturing, simply because porting them to a modern programming language or platform is very expensive and complex. You know the saying, "If it works, do not fix it", and this is especially true when we talk about i.e. core banking systems.


Nostalgia

 Pascal still holds a special place in the hearts of many programmers. 💖


Compilers

Compilers are available today, and some are free, thanks to Florian Klaempfl and others

IDE

The very popular IDE that can be installed on your computer locally is Lazarus.


Online IDEs

Some of the online IDEs are:

All of them are either free or have a free tier.


Conclusion

Pascal is still alive 🌞 why not try it?
