Choosing the IT industry means choosing a field full of challenges. For software engineers, the success or failure of a project is crucial. They often spend countless nights coding, sacrificing their mental energy. If a project fails, it means all their hard work has gone to waste, which can be quite disheartening. This article introduces the reasons that can lead a project to unknowingly and quietly head towards failure.
1. Member Turnover
Every company experiences turnover of employees or contractors, but frequent changes in key personnel can be a leading indicator of a project’s destined failure. There are many reasons why turnover can negatively impact a project. First, it can affect the morale of other team members, reducing productivity. Secondly, losing key individuals may result in the permanent loss of historical and critical information, slowing down progress. Finally, replacing team members requires training new ones to catch up with the team, which can be distracting and lead to increased development costs and extended delivery times.
2. Stop-and-Go Syndrome
Children are taught not to cry wolf. This serves as a warning against raising false alarms. This warning creates a cycle of “go! stop! go!” that can easily be overlooked in projects. A manager, client, or other stakeholders may urgently push their team, claiming the project must be completed by a certain date. Developers then work overtime on weekends, investing more effort. Then, just as quickly as the urgency arose, it suddenly halts. Months later, the urgency returns: “Hurry, we must ship by X!” and the same situation repeats.
This repeated urgency of stop-and-go will psychologically impact the development team. Developers will no longer believe in any urgency. In fact, they may develop a mindset that the project is not worth serious attention, as it will soon stop again, leading them to question why they should invest any effort.
So, do not cry wolf on projects!
3. Perfectionist Attitude
Many engineers have a perfectionist attitude. The problem with this mindset is that it is impossible to develop a perfect system, write perfect code, or launch a product at the most opportune time. Perfectionism is an illusion; if it becomes part of the company culture, it can lead to a product that is constantly revised until the company goes bankrupt.
The correct mindset is not perfection, but success. To successfully launch a product, what is the minimum success criterion? Set success standards and launch the product as soon as they are met. Afterward, features can be added and small bugs fixed using a boot-loader.
4. Accelerated Timetable
To rapidly develop an embedded system, the design team actually needs to slow down, which seems counterintuitive. Working under an accelerated timetable creates pressure and, more importantly, increases the likelihood of errors, reducing efficiency. Errors will directly affect the number of minor defects, which will subsequently increase testing and rework time.
Another issue is that when developers rush to meet an accelerated timetable, they may take shortcuts. For example, code may lack comments and documentation. Design documents like architecture diagrams and flowcharts may be absent. Instead, the design only exists in the minds of the programmers. Slowing down and doing things correctly will lead to a faster final solution.
5. Poorly Structured Software
Embedded software is the lifeblood of embedded systems; without it, products cannot function. Poorly structured software is a clear sign of impending failure. The system architecture of embedded systems needs to be flexible for future growth. It must allow for testing, debugging, and logging. A poorly designed system will lead to poor implementation, resulting in numerous software errors that are difficult to manage, ultimately leading to the project’s demise.
6. Misplaced Priorities
Developing a new product is an exciting endeavor. There are many tasks to accomplish, and companies are often eager to turn concepts into producible products. This rush is extremely dangerous, especially when production decisions arise.
A good example is when the mechanical design or aesthetics of a product drive its electrical requirements. Production tools are prepared for manufacturing before the electrical and software prototypes are validated. In such cases, there are always untested circuit boards that require adjustments. Projects that rush to try to pull everything together too quickly often end up taking longer and costing more due to modifications.
7. Scope Creep
Every project experiences scope creep, but the extent of it can be a decisive factor in whether a project succeeds or fails. The most dangerous aspect of scope creep is that it is insidious. One day, a simple sensor is added to the circuit board, and months later, more are added. These changes seem harmless, but they can be fatal.
The biggest problem with scope creep is that changes are often minor. At first glance, the changes appear to be just a few days of work. However, each small addition increases the complexity of the system. Complex systems require more testing and may need more debugging. Over time, scope creep can alter the system to the point where the original software architecture and design become outdated or even incorrect solutions! The end result is that a project can far exceed its budget, with actual progress lagging behind delivery dates, and the project shows little to no signs of completion.
Conclusion
No matter what type of embedded engineer you are, there is no guarantee that a new embedded system project will be 100% successful. Many factors influence a project’s success, and what we engineers need to do is minimize the failure rate. You can learn from the above summary to assess whether your project is on a slow path to failure.
