Work Breakdown Structure (WBS)

Work Breakdown Structure (WBS) is used to simplify and organize the important activities of the RFID project in a systematic way. WBS is the essential first step here, as we will use this structure to prepare the project schedule, calculate the budget, and perform the risk assessment of the individual tasks. It also helps us allocating the resources and assigning responsibility to the project stakeholders more effectively. We understood the importance of this exercise and so had subsequently held three separate meetings in November/December 2010 to brainstorm the details of WBS. A mind map is created using the online software Mind Meister. Although this software is powerful and easy to use, it only allows three free mind maps and we need to buy the license after 30-day trail period.

Overall, we decided to divide the project into six main elements: Plan, Process, Hardware, Software, Test, and Deployment. A maximum 2 sub levels will be included so that we could have better control of the overall progress. A mini-project could always be formed for the individual tasks if necessary.

• In the planning stage, we need to do project scoping, budgeting, scheduling, risk analysis, and forming of a steering committee to drive the project and the change management.

• For the process, we need to do a detailed mapping and simulation of the current manual process and the proposed RFID process. Sensitivity analysis will need to be conducted to understand how far we can tolerant the deviation of the simulated results.

• For the hardware, we need to determine the specifications, decide on the vendors, modify the existing warehouse layout, install the RFID equipment, prepare documentation, and train the stakeholders to run the hardware correctly.

• For the software, we need to integrate the RFID with the existing JD Edwards system. Hence, we need to select the right consultant, pick the right middleware, redesign the JD Edwards system code, migrate the RFID data to new server, prepare the documentation, and train the stakeholders to use the software efficiently.

• In the pilot testing, we must design the acceptance test in such a way that it will reflect all possible scenarios during full-scale implementation. If any errors are found during the acceptance test, we need to troubleshoot and provide remedies to fix the problem.

• In the final full-scale deployment, we have to make sure the right KPIs are established to sustain the benefits of the RFID. In addition, we need to ensure that the new system will be maintained and monitored periodically. A team should be set up to continuously drive the improvement plan of the system so that RFID benefits can be maximized at all time.

Project Scope

With no hesitation, we would like to express our intention in this project and discuss the scopes involved in this post. It is an honour to give our very best to share with you, every business aspects involved with the implementation of RFID in F&N Warehouse Management System.

Our objectives are:
  • To integrate RFID Technology in Storage and Distribution Network to achieve systematic product handling and storage.

  • To maximize data accuracy of product movement and minimize the human-related risk of management.

  • To achieve Real-Time Monitoring of Distribution and Excellent control of Product Quality within Distribution Network.
However, our project is started with an unexpected challenge...

One of our group members -- Tzuu Bin is having two-weeks business trip in Thailand. We have to carry out the discussion via MSN and e-mail, using "inefficient" internet service providers at both sides.


First, we have to discuss the scope for this project, which we think is rather broad and challenging. We cannot deny the fact that cost is the ultimate "STOP" caller in every ambitious and wonderful dream.

We came to a conclusion that RFID tag should be attached to the pallet or case, not on every single item (product). The latter will increase the cost tremendously, without bringing any clear economic impact. Domestic consumers will not benefit as the tag does not benefit them at all. Most importantly, the embeded RFID tag in the product packaging can hardly be recollected for recycling. The return on investment (ROI) could be very low.

If we consider tag on either pallet or carton crate, the tag can be easily recycled for each product cycle, the quantity of tag purchase can be shrank to 60000 at
the initial investment, with annual replacement of 5000 for damaged tags (assumption). This saves a lot compared to tens of thousands per day.

Then, we need to outline the stages (phases) of RFID-technology implementation. With constructive discussion held and adequate research done, we concluded the following three phases of roll-out .

Phase 1
  • RFID Business Analysis
Phase 2
  • Technical Assessment
  • Pilot
  • Integration assessment
Phase 3
  • Delivery
  • Promotion

Besides, the support from top management is strictly required. We intend to convince the stakeholders with the following benefits gained over the proposed investment:

Cost – Working Capital Reduction
Adoption on RFID technology enables less man-hour on quality inspection and prevents manual recording of information for each crate and pallets, thus reducing human capital cost in warehouse.

Revenue – Profit Increase
- Reduce labor costs in stores and warehouses (long-term).
- Decrease inventory with better information management.
- Reduce shipping loss and inventory loss due to mis-manifest, mis-routed,
pilferage, damage, shortage and duplicate order.

Improve Efficiency
Improve asset visibility, leading to improved asset utilization and working capital efficiency.

Improved Product and Service Quality
Improve product return management - manufacturers could quickly locate and recall faulty products, even before they reach consumers.

Legal and Regulatory Requirements
Temperature control ensure safety and quality, ensure longevity (shelf-life) of food products.

Improve Customer Satisfaction
Better information management of stock level will assist sales department in making necessary business decision, assisting customers on orders and enquiry.

Increase Visibility
Real time information can be obtained for quick management decision, e.g. routing, sorting and recalls.

Improve Collaboration
Increase inventory accuracy, assist accurate demand planning and reduce inventory cost.

Next, we have to decide the timeline. We estimate 15 months of transition and implementation.

In order to formulate the budget required for this project, we have to list out all the resources we need, and do research on the costs from available sources online.

In the meantime, we also discuss on the hidden cost that might appear during the implementation of RFID in warehouse.

The basic but critical elements of a RFID system include tags, printer/encoders, reader/encoders (interrogators), sensors, middleware (for data-filtering and data-flow management), and, if needed, some software adaptations to enable legacy applications and systems to receive RFID-generated data.

The integration of the RFID into the existing program (hardware and software system) and the support from third-party technical consulting team constitute major percentage of our costs. The team is required to provide single technical consulting engagement or execute a complete turnkey international solution through its comprehensive reseller and systems integration network.

Subsequently, we have to define who are the participants (or stakeholders) required in this project and their roles and responsibility respectively.

Job Title
Duties
Project Manager/s
Manage the progress of the project and make sure the tasks are executed within budget.
IT Department
Concerned with technical information regarding the physical integration of the RFID system into the current IT infrastructure. This includes information such as the hardware/software structure, security issues and standards.
Process Management group
Interested in a potential change of processes when implementing an RFID system, the integration of new processes into the existing business processes, and evaluating how processes can operate more efficiently.
Legal Department
Handles the legal issues associated with RFID and requires information such as related legislation, to ensure that the firm is complying with all relevant national legislation.
Human Resources (HR) Department
Need to be provided with information regarding topics such as health implications from the use of RFID or also employee rights
Communication Department
Requires information on RFID so that it can communicate information to various parties.

Then, we have also converse the expectation of stakeholder and the critical success factor.

Stakeholder
  • Management
  • Finance (sponsoring department)
  • Team member
  • RFID Technology supplier
  • RFID service provider (consultant)
  • End user
Expectation & Success Factor

Strategic level
  • Creating strong internal and external motivation for improvement
  • Developing a clear RFID strategy
  • Partnership with competent RFID providers
  • Strengthening mutual understanding in organization
  • Top management support and commitment from leadership

Tactical/management level
  • Determining which practice should be incorporated into RFID system
  • Facilitating equipment vendor’s investment
  • Integrating RFID into a existing IT architecture
  • Proper staff training
  • Starting with small RFID project (trial)
  • Utilizing a cross-functional team

Operational Level
  • Avoiding major process change/ limit process changes
  • Coordinating improving procedures
  • Integrating the data collected
  • Lack of comprehensive facts and data
  • Using cost-effectiveness reusable tags

The following assumptions were made in preparing the Project Plan:
  • Management will ensure that project team members are available as needed to complete project tasks and objectives.
  • The Steering Committee will participate in the timely execution of the Project Plan (i.e. meeting when required)
  • The Project Plan may change as new information and issues are revealed. Mid and upper management will foster support and “buy-in” of project goals and objectives.

The following represent known project constraints:

A relatively high cost
Implementing a fully functional RFID system incurs multiple costs, including tags, readers, printers, infrastructure, consulting, training, change management, and service provider fees. There is also the cost for additional labor that will invariably be needed with early stage of RFID deployments.

Business process changes
Automation process through RFID technology requires a new working methods ad performance measurement for the supply chain in F&N. There will be significant impact on the whole organization, especially on warehouse operating protocols.
Thus, the designation of RFID system must consider new processes and procedures to automate tasks and decision making, as well as considering the impact on the whole organization.

Risk to the nature of business
Although RFID is a mature technology; it is not popular among dairy product manufacturers. The lack of ROI information upon RFID deployment increases the risk of the business nature.
Additionally, RFID technology is widely deployed in U.S and Europe country but not in Singapore. The lack of established local vendor and experienced consultants in the region are few issues we have to consider.


At last, your comments and constructive suggestion are strongly welcome.

WHY F&N?

We have sufficient knowledge on the existing problems encountered by F&N Management, after a month of case study we did in last semester. This company is chosen again, in which we would like to propose RFID implementation to the issues we discovered in previous studies.

Let me share with you some of the issues encountered in F&N’s warehouse operating process.


All F&N finished products are stored in the designated cold rooms of the warehouse instantly after being released from the production. Table below shows the storage location for all finished goods.

Storing Location
Products
CR 1
Yoghurt, margarine, sour cream
CR 2
Tea
CR 3
For order-picked goods and extra goods that their specified cold rooms are unable to accommodate
CR 4
Juices
CR 5
Milk (All brands, Magnolia, Farmhouse, Daisy, Masters, etc.) & Soya

Warehouse personnel will usually receive the products placed in the crate or carton and store them in a temporary waiting room. The crate or carton will then be stacked on the pallets and moved to the metal rack. A tally sheet is used to record the quantity received, product type, expiry date, pallet number and rack number. Upon recording, these documents will be handed over to the warehouse clerk for data entry into the ERP system (JDE).

Photo below shows the crate which consisting of 250ml Aloe Vera Juice, with expiry date on 3rd Aug, and the pallet number is 24.




We can conclude that F&N does not have a systematic approach to guarantee the first-in-first-out rule, real-time product movement, and just-in-time product retrieval system. Every process is done manually.

Such inefficient practice gives rise to issues of data accuracy and reliability. Human error might occur during the data-entry. Time and manpower (and also man-hour cost) wasted may cause delay in the storing process, which increases the risk of product damage.

In the case of quality issue, F&N may have difficulty to trace and recall the defective products or the affected lots. It could be more disastrous if there is a human error during key-in procedure. The dangerous lots may go undetected eventually, costing its customers’ health.

   How to solve???

To improve quality product handling and storage, F&N should integrate certain degree of automation to the current storage system. This will help to increase the accuracy of the inventory control, order processing and achieve error-free handling in the distribution cycle. 


The proposed solution would be the implementation of RFID (Radio Frequency Identification) technology in product-handling and storage cycle, offering hassle-free, quick and accurate identification of product category, tracking, and tracing of the product movement without involving human to read and record data. Strong capability in data storage provided by RFID will also assist the automated collection of important real-time information for immediate business decision. Localized temperature indicator can also be innovated to be part of our RFID system, to monitor the temperature fluctuation along the product movement, and hence reducing the risk of products damaged.

Our project title: Implementation of RFID technology in F&N warehouse.

Belows are some introduction for RFID technology:

RFID is getting more popular nowadays and has been widely used in several industries including Government units. For instance, Land Transport Authority has used RFID in Electronic Road Pricing (ERP) system in city areas and expressways since 1998. Basically, RFID Tags are made of three parts:


1. The chip holds information about the physical object to which the tag is attached.


2. The antenna transmits information to a reader (e.g. handheld, warehouse portal, store shelf) using radio waves.


3. The packaging encases the chip and antenna



Tags come in two varieties:
* Active
* Passive

Passive tags derive their energy from radio frequencies transmitted by readers. The cost is less compare to Active tags because they do not require batteries. Active Tags contain their own battery and are always on.
