11、6REQUIRED APPROVALS56THE AS-IS PROCESSPurposeThe Business Requirements document captures the As-Is Process, identifies improvement opportunities and defines the To-Be Process. It also documents business scenarios that describe the workflow and business processes that the software solution should add
12、ress. It elaborates on the available inputs, required processing (including timing and frequency considerations) and the required outputs. Each scenario in turn helps in defining what solution features would be required.The document is a supporting tool to decide on the features and functionality ne
13、eded in the solution. The use case scenarios are later used to validate and accept resolved issues. The document should be used at the start of the Solution Architecture phase, and continually reviewed throughout the implementation, as more information becomes available.Overview of OperationsOvervie
14、w of business processAt HW the planners of different department are in charge of materials planning. And the planners only plan the products for their own department. All the planning processes are separately. The whole process is:a. Gathering and process all demands with MDSb. Generate MPSc. Run MR
15、P and Schedulingd. Process WO and PRe. Execute WO and PRThe Bill-of-materials for a typical Huawei sales order item is as in the following figure:Note that PTO at the top of the BOM is a packing process, and does not have any routing. The sales order line item will be at ATO level. SMT factory is in
16、 the BTS mode, producing according to forecast. There is a SMT inventory warehouse for SMT boards. ATO factory perform the final assembly and testing when Huawei receives the order. In simple words, Planning at the ATO level is ATO. The Planning at the SMT level is MTS. ATOs are unique to customers
17、whereas SMTs are not. Thus, multiple unique ATOs share common SMT. MDSIn MDS phase, planners gather all the forecasts first. Then they will check and adjust the forecasts. After confirm the forecasts, the planners gather all the demands together, that mainly coming from the following four waysa. Dem
18、ands from marketing plan departmentb. Demands from the business department (real sales orders)c. Internal demands between different departmentsd. Independent requirements from different departmentsAfter this phase, planners know all the demands that needed to be planned.MPSTo generate MPS, planners
19、first generate a MPS plan and get the relation reports. Then they adjust the MPS result before sending to te planning manager for approval. After the planning manager confirmed the MPS result, the planners need to maintain the new MPS plan. Then the MRP scheduling plan is generated. When adjusting t
20、he MPS plan, the planners consider the five factors below:a. Version changeb. The capacity constrain of the key resourcesc. The requirements change from the marketing, and changes in internal requirementsd. The planning percentage is not accurate, cause the demands are not mapping well with the hist
21、ory datae. Other things such as basic data not accurate, the planning attribute not correct and special orders etc.Purchasing Purchasing forecastThere are two types of purchasing forecast, one is weekly forecast, and the other is monthly forecast.Weekly forecast covers three months purchasing foreca
22、sts. The materials are mainly locally supplied. And the purchase lead time are relatively short. Some examples are packaging materials, PCB etc.Monthly forecast covers nine months purchasing forecasts. Special materials are only purchased when the real sales orders are received. The MAX/MIN method a
23、llows MAX and MIN inventory for the materials. When the materials inventory is lower then the MIN value, they will be purchased use the following formula:Purchase quantity = MAX Inventory PO (time based) + Required quantity of sales order (time based)Manufacturing planThe planners generate the produ
24、ction reports using the manufacturing data of the first three weeks. Planner only releases the manufacturing orders that begin in the next two days in the manufacturing execution system.Normally planners only release work orders when the materials of work order are all ready in the inventory. But in
25、 some urgent cases, they also release the work order even when not all the materials are all ready. The shortage material may be arriving within the following two days. Business Scenarios Introduction:Based on the interview questions and discussions with BU process owners and factory schedulers, var
26、ious business scenarios that represent FPs business requirements have been compiled. This document will be a live document and will get updated with more details on the existing scenarios and also new scenarios and requirements will be included as the project goes though conceptual design and soluti
27、on architecture. Business Scenario Detail: 1. Material assignment according to Demand priorityUser Scenario: Order priority for sales orders and forecast orders are assigned by Sales according to Huaweis internal rule. FP must assign material and allocate capacity based on the order priority. Planne
28、rs/Users Impacted: PlannersList of Causes/Triggers for Scenario: Sales, forecast and internal demands entered from MP and ERP need to be prioritized and planned.Related Scenarios: Frequency: Demand priority logic is used every time the planner produces a plan. Currently the plan is produced once a d
29、ay.Decision to be Made/Action to be taken: The sequence of which the orders are being fulfilled. When a high priority demand has material shortage, low priority demand can be fulfilledCustomer/Decision Maker: PlannerTime Allowed to Make Decision: Input Data Requirements: Every demand, as well as for
30、ecast, must have a priority. Logic Requirements : Demand sort priorityInformation Requirements for Decision/Criteria to Make Decision: Since FP plans all the orders in factory for all product family, product etc, priority rule be set at a detailed granularity to provide clear tie-breaking rules for
31、demands from different departments. Description of DeliverableBusiness Rules: The priority typically based on product family, customer, and order entry date. User Interface/Reporting Requirements:Key Functionality: Demand sort priorityUser Access to Data and Interfaces: Planner can see all the deman
32、d information in the Orders screen.Business Scenario Detail: 2. PTO AND POC should be delivered and planned togetherUser Scenario: POC items appear as line items in the sales order. POC should be delivered with PTO item.Planners/Users Impacted: PlannerList of Causes/Triggers for Scenario: When Sales
33、 order or Forecast coming from MP or ERP, the POC and PTO should be in the same order and different lines.Related Scenarios:Frequency: Decision to be Made/Action to be taken: When one line item of the order (PTO or POC) is late, the other will be also delayed. And they will deliver together.Customer
