Formalizing the User Requirements

One of the most difficult things in developing information system is defining the requirement. Usually, users do not understand how to define their requirements. Sometimes, they also do not know what is their problems. They only state that they need information technology to support their jobs. As a result, it is very important for us to formalize the requirements.

IT developers should define the requirement first. There is a lot of approach in definining and formalizing the requirements. One of the approach is using software requirement spesicification (SRS) document. The document template could be downloaded from the internet. An example of the document could be accessed from this address https://services.brics.dk/java/courseadmin/SoITS/documents/getDocument/CafeteriaOrderingSystem.pdf?d=52680.

If you understand use case diagram, it is better for you to use it when defining the functional diagram. You can use computer software or pen when making the diagram. After finishing the diagram, then you can put the diagram in the SRS document.

SRS document is very important when you developing the new system, especially when there is no similar system in the market. If you prepare the document well, then you can define what the system to be developed.

Unfortunately, in Indonesia there is not many developers who develop their system started from SRS document. That is the reason why many projects fail in this country. Usually, after constructing the system, users argue that the system is not like what they need.

If you do want your projects fail, please make sure you have prepared your SRS document.

Serving the Visitor

Yesterday, I had some guests from Ministry of Civil Service Empowerment and Bureaucratic Reform. Currently, they are developing Government Resource Management System (GRMS). They have researched the implementation of some systems in each ministry. For example, they learned that e-planning has been developed at Ministry of Planning, e-budgeting at Ministry of Finance, e, procurement at Procurement Policy Agency, and so on. However, they never learned about the implementation of e-controlling system. As a result, they could not finish the GRMS concept. To finalize the concept, they were searching e-controlling system. They were very lucky when they received information from one of deputies at Ministry of Civil Service Empowerment and Bureaucratic Reform. According to deputy, he heard that my office was in the process of implementing e-controlling system. That was the reason why they visited my office.

Management styles born in the days of sweatshops and typing pools, based on time clocks and counting heads, just don’t work with a mobile workforce. Whether your employees are down the hall or thousands of miles away in a client’s office, if you’re not measuring by results, you really don’t know who’s productive and who isn’t.
