System Scope
Business Problem
Currently the patient orders of health care facilities are being taken over phone and most of other
work is also being done manually and billing is being done by third party which is not working
according to the requirements. The business of ChemExec is being increased day by day and it is
not easy to manage complete functionality and inventory management manually.
Purpose Statement
The main objective of the ChecmExec system is to maintain the all records from taking orders to
delivery and billing should be computerize. The complete ChecmExec system should be
computerized.
Benefits
There are lots of benefits of the computerized ChecmExec system as shown below-
- The important data will be managed easily.
- The billing is very critical and it will be accurate.
- The records will be saved for future use also.
System Capabilities
The system will be capable of doing all the tasks required in ChemExec like below-
- The system will be capable of taking patient orders from Health Care Facilities.
- The system will be capable to deliver all orders to Health Care Facilities on time by doing
all internal tasks like making manifests, assembling all components of orders etc.
- The system will be capable of doing billing.
- The system will be capable of managing inventory.
Exclusion

Remove the separate working of all different branches of ChemExec. Make a single system that
will work for all branches.
System’s FURPS+ Requirements
The requirement is a capability or condition which is necessarily obeyed by the system. There
are different types of requirement e.g. Functional, Non-Functional etc.
FURPS+ categorize the requirements like below-
F- Functional Requirements
U- Usability Requirements
R- Reliability Requirements
P- Performance Requirements
S- Supportability Requirements
+ indicates that there are some other requirements also likebelow-
- Design Requirements
- Physical Requirements
- Interface Requirements etc.
Functional Requirements
There are different functional requirements in ChemExec system as shown below-
Number Requirement
1 Health Care Facilities will order the cases.
2 The ChemExec system will accepts pharmacy orders for patients from Health
Care Facilities.
3 Health Care Facilities submit Patient’s prescription.
4 System will generate case manifests for each floor or wing of each client.
5 Assign case manifests to pharmacists.
6 PA collects all drugs of a patient in plastic drawer.
7 PA assembles all components of order.
8 Pharmacist makes the final check before order.
9 System will store manifest into computer.
10 Process billing online.
11 PA assembles all cases.

12 Delivery Persons delivers the orders to the health Care Facilities.
Usability Requirements
There are different non functional usability requirements in ChemExec system as shown below-
Number Requirements
1 The ChemExec system should guide users to work on the system.
2 The ChemExec system should be easy to understand.
3 The ChemExec system should not obstruct the users.
4 The ChemExec system must be easy to correct mistakes.
Reliability Requirements
There are different non functional reliability requirements in ChemExec system as shown below-
Number Requirements
1 The ChemExec system should be designed as a robust and lenient to operator
errors.
2 The ChemExec system should recover from power cuts etc.
3 The ChemExec system should be reliable with less number of interruptions.
4 The ChemExec system must give stable results.
Performance Requirements
There are different non functional performance requirements in ChemExec system as shown
below-
Number Requirements
1 There should not be any restriction of time or place on the usage of system.
2 The ChemExec system should response quickly.
3 The ChemExec system should be able to dialog with users all the time.
Supportability Requirements
There are different non functional supportability requirements in ChemExec system as shown
below-
Number Requirements

1 The ChemExec system should support different languages.
2 The ChemExec system should be maintainable.
3 The ChemExec system should be able to migrate to upgraded hardwares or
softwares..
4 The ChemExec system should be able to migrate to different networks.
Design Requirements
There are different non functional design requirements in ChemExec system as shown below-
Number Requirements
1 The ChemExec system should be designed in the way that it will work many
years.
2 There should be good interface to interact with the users.
