Technology As Innovator

3. ERP System Characteristics

• Modular design comprising many distinct business modules such as financial, manufacturing, accounting, distribution, etc.
• Use centralized common database management system (DBMS)
• The modules are integrated and provide seamless data flow among the modules, increasing operational transparency through standard interfaces
• Flexible and offer best business practices
• Require time-consuming tailoring and configuration setups for integrating with the company’s business functions
• Modules work in real time with online and batch processing capabilities
• Internet-enabled
• Financial and business information is often generated automatically by ERP systems based on data previously entered, without further human instructions
• ERP provides business intelligence tools like Decision Support Systems, Executive Information System, Reporting, Data Mining and Easy Warning Systems for enabling people to make better decision and thus improve their business processes

Apart from motivationally writing for the web, I have been invited to universities as a motivational speaker to talk about the IT industry and IT occupations with IT students.

What question do you think is most frequently asked?

What programming languages and tools are currently used in your company?

It is not a surprising one because the same question has been asked much more frequently on technical forums and newsgroup and has caused so much debates on T-tool vs. U-tool and more heatedly, X-language vs. Y-language.

And my answer is

“It is nice that you are preparing the knowledge and skills that you think your potential employers will seek. However, skills and experience in a particular programming language is not the only technical skill employers seek in candidates. They’re also looking into the foundation technical knowledge, such as but not limited to: Object Orientation, Design skills, Software Methodologies, Data Structures and Algorithms, Database Design, Architecture, Computing Theory, that empower your programming skills. You may do programming with, let’s say, Java relatively well in some situations without the above knowledge, but if you are thrown into a more complex project to build a huge product, the risk is high.

One example. You spend two to four years in college polishing your skills in X language that you predict will (still) be hot in a few years when you graduate. When you do graduate and apply for jobs, if they say “Sorry, X is old. We’re needing Y people”, what will you do? Spend the same amount of time learning Y? No, it’s not the way it should work. Foundation knowledge is the root, languages and tools are leaves. Equip yourself with the foundation, and when technology changes (is IT a slow changing area that does not change every 6 month or so?), you can adapt more easily.

When you have mastered the foundation knowledge, and possessed significant experience in using programming languages, which IDE is not a bug big issue.

Besides, about recruitment, technical skills are not the only evaluation criterion. Think about soft skills and attitude too.”

I was thinking about my profession

The number of Business Analysts and System Analysts required in software companies is not that many compared to developers; in some smaller companies with less formal process definition, some developers take the Analyst role. If the need for Analysts were higher, this question could have been asked: “What modeling languages and tools are currently used in your company?”

The answer is simple: Unified Modeling Language. UML itself has been a well-established language for modeling. More of a reason why it has become so popular is due to the promotion of UML by RUP.

But once again, UML is a language. The case is not much different from that of programming languages. Knowing UML is not enough to perform all tasks Analysts do, Business Process Modeling for instance - and a new standardized set of notations named BPMN (Business Process Modeling Notation) is being proposed.

Underlying UML skills are Modeling skills. Modeling languages are used to present information in a more visual (and structural?) way. You need to know what model or diagram should be used to present what kind of information at what time in what situation to whom.

Model is one kind of information. In order to develop solid Modeling skills, Information Processing skills and Data Analysis skills need to be developed first or in parallel.

With all those skills at hand, you will be able to guess how shapes are categorized and may quickly locate the right notations you need in Modeling tools, no matter if it’s Rational Rose or Visio or Enterprise Architect or so on.

After you have created a good piece of model, you may want to present it to customers or other teams in your project. Presentation skills may help.

Side discussion: Model vs. Diagram

Throughout this article, I have used Models consistently, without mentioning diagrams. The may raise question since “UML diagram” is a very common terminology. The reason is because Analysts produce visualizations which are not diagrams too. Organization charts, map, prototype are just a few to name. ‘Model’ covers all of these, of course including diagrams. Also, one trivia is that the word may remind the fact that information systems actually model the real world.

Conclusion

So to conclude, foundation knowledge is required in any profession. Technology and tools change so quickly, but concepts do not as quickly. Build your internal strength should be the higher priority.

1. Definition

Enterprise Resource Planning Systems are software systems for business management, encompassing modules supporting functional areas such as

• Planning
• Manufacturing
• Sales
• Marketing
• Distribution
• Accounting
• Financial
• Human Resource Management
• Project Management
• Inventory Management
• Service and Maintenance
• Transportation, logistics and e-Business

The architecture of the software facilitates transparent integration of modules, providing flow of information between all functions within the enterprise in a consistently visible manner. Corporate computing with ERPs allows companies to implement a single integrated system by replacing or re-engineering their mostly incompatible legacy information systems.
