1 产品包需求分解设计需求 Decompose offering requirements into Design requirements
11 确定操作方式
产品包需求根面容操作方式进行概括写入表1中:
操作环境顾客户眼中操作
顾客户期操作
成尺寸重量电源冷环境制造服务等方面操作限制
限制范围实际操作
方面带影响:成质量市时间顾客满意度兼容性等等
客户户操作表示出吃惊(包括正面负面)
For each offering requirement summarize the Operational Scenario by noting in the Table below
the operational environment and the operation from the customeruser view
the customeruser expectations for the operation
the constraints on the operation in terms of cost size weight power cooling environment manufacturing servicing etc
the actual operation within the constraints
the consequences in terms of cost quality time to market customer satisfaction compatibility etc
any surprises for the customeruser (both positive and negative) for the operation
操作方式进行概括例子:
Another example Operation
产品包需求:中国偏远区进行紧急呼户希旁边呼时中国偏远区进行紧急呼掉线
Place urgent calls from remote areas of PRC Caller (user) wants to place urgent call from remote areas of PRC in the presence of other callers without call dropping etc
111 操作方式进行概括程 Operational Profile
1) 操作环境文顾客户角度考虑操作 Context or operational environment and the operation from the customeruser view
呼偏远山区快速移动客车车电话电池足等等 Caller may be moving at high speed in remote hilly areas may be in a bus with numerous other callers battery may be weak etc
2) 顾客户操作期 Customeruser expectations for the operation Classify the expectations as mandatory competitive or nice to have Example Mandatory Caller places call and is connected within five rings Competitive Caller connected within three rings
Nice to have Caller connected within one ring
期划分强制性具竞争力者:
强制性:呼呼振铃五次接通
具竞争力: 振铃三次接通
: 次振铃便接通
3) 操作方面受限制:成体积重量功率冷环境制造服务等 Constraints on the operation in terms of cost size weight power cooling environment manufacturing servicing etc
呼愿提供紧急呼便利外付费愿支持紧急呼功手机额外付费希电池时间越长越许必须基站具支持紧急呼额外功部限制原基站已占功率基站补充新功求进行重新设计
Caller is not willing to pay a premium for the convenience of placing urgent calls Caller is not willing to pay more for the handset and want the power to last as long as possible Therefore additional functionality to support urgent calling may have to be implemented in the base station Internal constraints are that the base stations are already using all the power available so implementing additional functionality in the base stations requires redesign
4) 实际系统操作时量考虑限制素注意考虑成质量市时间客户满意度兼容性等方面影响 Actual system operation that is possible taking the constraints into account Make note of the consequences in terms of cost quality time to market customer satisfaction compatibility etc
例:必须基站重新进行设计支持增加功样便会增加成求运营商(顾客)现基站进行升级会增加成负担必须负担转移呼里 Example The base stations have to be redesigned to support additional functionality increasing costs and requiring providers (customers) to upgrade existing base stations imposing a cost burden which they have to pass on to callers
5) 顾客户操作吃惊反应(正面负面)重视 Make note of any surprises for the customeruser (both positive and negative) for the operation
例:果需项服务额外付费(运营商产生追加成)话呼会愉快果呼边远区够稳定进行紧急呼话便会高兴运营商必须升级基站会愉快 Example Callers will be unhappy if they have to pay more for the service (because of the additional costs to providers) Callers will be happy if they can place urgent calls reliably from remote areas reliably Providers will be unhappy about having to upgrade the base stations

Decompose the offering requirements into design requirements based on the operational scenarios and specify the acceptable parameter ranges for each design requirement using the following Table as an aid Offering requirements should be decomposed into Design requirements of different types including
Ÿ Functional
Ÿ Environmental
Ÿ Performance
Ÿ Robustness
Ÿ Reliability
Ÿ Maintainability
Ÿ Usability
Ÿ Security
Ÿ Weight
Ÿ Power
Ÿ Size
Ÿ TransportabilityMobility

实现追溯性已分解描述设计需求应特定产品包需求建立明确联系 Design requirements that are already stated at the decomposed level should be clearly associated with specific offering requirements for traceability purposes

1 设计需求合理化 Rationalize the design requirements
面表格中设计需求进行合理化工作:
1) 表设计需求进行分类
2)相互支持需求合项需求
3)处理互相突需求 分析优劣势重新进行优先排序者采取折衷方案
4)含混清需求进行澄清 外部部员进行
5)整合冗余需求
6) 需需求转入点子库
7) 修正产品包需求设计需求表
Rationalize the design requirements from the above table as follows
1) Categorize the design requirements into the categories in the Table below
2) Combine mutually supportive requirements into a single requirement
3) Resolve conflicting requirements look at pros and cons reprioritize or compromise
4) Clarify the confusing requirements ask external and internal parties for clarification
5) Consolidate redundant requirements
6) Transfer the unecessary requirements to the idea bank
7) Revise the Offering Requirements and Design Requirements Table
