Constraint: influencing everything


What is a constraint?

Definition of constraint

Hello there! Word of the day – constraint. BABOK® v3 defines it as an influencing factor that cannot be changed and that places a limit or restriction on a possible solution or solution option. There is another definition of constraint, by Karl Wiegers in Software Requirements, 3rd Edition: constraint is a restriction that is imposed on the choices available to the developer for the design and construction of a product. Taking these two, we understand that constraints narrow our options for something related to a given context.

Understanding constraints

Constraints describe aspects of the current or future state. These aspects are something that organizations can only sometimes change, usually – either complying or selecting other options to achieve desired. Business analysts are responsible for eliciting, documenting, and examining restrictions to the requirements analysis, solution design, and implementation.

Constraints are not requirements – they are internal or external factors to consider. Moreover, constraints may be something that the situation hides or something that is even unknown. For example, people tried (and somewhat succeeded) flying long before they understood the science behind it. The other thing is that constraints sometimes are not formally imposed. For example, no one could affect the concept of time; at most, we have found a way to measure it. What’s more, constraints may be a part of a stakeholder’s personal experience, characteristics, and capabilities. For example, the firm belief in some way of doing things, education, religion, personal attitude, and other items may highly affect and constrain the valuable solutions to that group.

Types of constraints

Here are some common types of constraints in business analysis and software development, along with examples.

Internal factors

  1. A budget limits the amount of money available for a project. Examples include limited development or infrastructure funding or unexpected cost overruns that impact the project’s financial resources;
  2. Scope limits the extent of a project’s requirements or deliverables. Examples include project timelines, resource availability, or constraints on the functionality or features of a product;
  3. People. It’s all about the limitations in personnel resources available for a project. Examples include a need for more skilled employees, limited availability of contractors or consultants, or staffing restrictions due to budget constraints;
  4. Skills are related to specific expertise or knowledge required for a project. Examples include a lack of domain knowledge or specific technical skills needed for the project or limited access to training and development opportunities;
  5. Technology constraints can include limitations on the software languages, frameworks, licensing, platforms, or environments used in a project. This can also include connection capabilities or 3rd-party integration limitations, which can impact a product’s overall functionality and compatibility.

External factors

  1. Regulatory constraints. This group relates to specific laws or regulations the team should follow in a project. Examples include compliance with the Americans with Disabilities Act (ADA) for government websites in the USA or adhering to GDPR requirements for data privacy in the European Union;
  2. Legal constraints arise from contracts, agreements, or legal considerations that we must consider. Examples include contractual obligations with stakeholders or intellectual property considerations that impact the development process;
  3. Ethical constraints arise from moral considerations. Examples include ensuring ethical sourcing of materials or avoiding potential conflicts of interest in the development process;
  4. Cultural. These constraints arise from differences in language, religion, or other cultural factors that may impact the development process. Examples include adapting products for different cultures or incorporating diversity and inclusion initiatives;
  5. Industry standards are constraints related to specific guidelines or best practices. Examples include adhering to software development methodologies, following established security standards, or complying with industry-specific regulations.

By understanding the various types of constraints and their potential impact on a project, business analysts and software developers can identify and address constraints proactively, ensuring that projects are completed successfully and efficiently.

How to handle constraints?

When dealing with business analysis and software development constraints, it’s crucial to have a plan to handle them effectively. The following steps can help teams to manage constraints:

  1. Identify. The first step in addressing constraints is to identify them. This involves recognizing any factors impacting the project’s time, budget, or scope;
  2. Document. Once constraints have been identified, they should be documented. This helps to ensure that everyone on the team is aware of the limitations and understands their impact on the project;
  3. Assess. After registering constraints, the team should assess their impact on the project. This involves analyzing the potential consequences of the limitations and identifying any risks or issues that may arise;
  4. Prioritize. When facing multiple constraints, it’s important to prioritize them. This involves determining which constraints are most critical to the project’s success and focusing on addressing those first;
  5. Communicate. Effective communication is essential when handling constraints. The team should keep stakeholders informed about any constraints, their impact on the project, and any progress made in addressing them;
  6. Review. Finally, it’s essential to review the handling of constraints regularly. This helps to ensure that the team is addressing constraints effectively and making progress toward the project’s goals.

By using these building blocks, teams can proactively and effectively handle constraints in business analysis and software development, resulting in successful project outcomes.

Theory Of Constraints (TOC)

What is TOC?

The Theory of Constraints (TOC) is a management philosophy developed by Eliyahu Goldratt that focuses on identifying and improving the bottleneck in a system. The underlying principle of TOC is that any system has a limiting factor that constrains its output and profitability. The entire system can be enhanced by identifying and improving the bottleneck.

The TOC approach is rooted in the idea that businesses should maximize their throughput or the rate at which they generate revenue rather than focusing solely on reducing costs. When organizations focus on optimizing individual components of the system, it can harm the overall design. Instead, a holistic approach that identifies and optimizes the bottleneck is critical.

Understanding TOC

The TOC involves several steps. The first step is to identify the bottleneck in the system is to analyze performance data. Once the bottleneck has been identified, the focus shifts to improving that specific constraint. This involves identifying the root cause of the bottleneck and developing solutions that address it.

One of the critical advantages of TOC is its ability to prioritize improvements based on their impact on the system as a whole. Rather than making changes that provide incremental gains, the focus is on making changes that significantly affect the system’s output. The TOC also emphasizes the importance of ongoing improvement. Organizations can achieve sustained growth and profitability by constantly monitoring the system and looking for opportunities to optimize bottlenecks.

Despite its benefits, the TOC has some limitations. Identifying the bottleneck in complex systems can be challenging, and addressing the constraint may require significant resources and investment. Additionally, there may be cultural or organizational barriers that make it challenging to implement changes.

In conclusion, the TOC is a powerful management philosophy that provides a holistic approach to improving organizational performance. Organizations can achieve sustained growth and profitability by focusing on the bottleneck in the system and prioritizing improvements that enhance overall throughput. However, it requires ongoing monitoring and investment to ensure success.
