After the school network billing system project was launched, a common card point is that needs research is not done."We need a system that can charge."More specific. The answer is blurry.——"I guess it's just a collection."、"Support a variety of packages."、"I'm going to get a little bit of a connection with the campus."The answers are selected, and the supplier scheme is available, but it turns out that the real scenes are not matched. Often the questions are not asked right at the research stage, and the business community is questioned because they don't think about the details.
First question."How do students use the Internet now?"Ask me again."How do you want to use it?"
The starting point for the school network billing system should be the real state of use of the current network, not the ideal state as it is imagined."Status": What equipment do students use to network? When are the peaks of the Internet in dormitories, teaching areas, libraries? There is no free flow quota. Who manages the back-office account for these devices? What's the most frequent question about user reporting?"Designing the future with no resources"The trap.
Take it."Cost particle size"Ask specific.
The operator said"Personally"Specific particles include: by school number, mobile phone number, or MAC address? The dormitory account is by bed, bedroom, floor. When do graduate students' accounts go out? How do you handle the student transfer numbers?"Border"Unable to handle. The more detailed the particle size is, the more clearly the system ' s capability requirements are and what is supported and not supported in the vendor programme is clear.
Take it."User complaints scene"List
If only in the course of research"What's the problem now?"And the answer is often to..."The net is slow."This is a general statement. The better answer is:"What kind of questions have users complained most in the last three months?"The list of complaints is classified as unopened: the certificate page is not accessible, it has been certified without access to the Internet, the billing balance is not good, there are frequent circuits connected, specific equipment cannot be identified, night-time network breaks are not recognized, etc. Each type of complaint corresponds to a specific scenario that the school network billing system addresses.
And the details of the financial interface.
If a school network billing system involves fees, it is necessary to switch financial processes. The study needs to ask: do you have to take the fee to go to the campus card or to go to third parties for payment? How long after the charge comes in? How does the refunds go? Can the balance be carried over? What are the rules for carrying forward? How do invoices open?
The network management team's capacity is to be assessed.
When the school network billing system is online, day-to-day maintenance is done by the web information centre."What do you want?"And ask me more."Can the transport team handle it?"For example: How many people are currently in charge of network maintenance at the Information Centre?×24 Hourly response is possible? What's the backup mechanism for a database? How much tolerance does the operator have when it fails to pay? The answers to these questions determine the complexity and wiring of the system.
Don't miss the student group.
The end-user of the school network billing system is a student, but research often only asks school management and teachers, ignoring the real ideas of the student community."Collective complaints by students"The student is very capable of voting with his feet, and an unfriendly system of billing makes the school ' s reputation worse among students.
Write findings into enforceable files.
We're done with the research. We must get one."Statement of requirements"The demand document is the basis for rating, when it is implemented, and the demand document is the basis for change. The school network billing system has a long project cycle and many participants, no solid demand file is at its bottom, and there are high chances of running off.
