Lab 9.1.2 Editing and Organizing the Existing Information

Step 1: Collate and organize the information
a. Gather and read through all the project documents that you created in previous labs.
b. Ensure that multipage documents are together and that the pages are in the correct sequence.

Step 2: Review the existing information
Ensure that the documents are complete and contain the information specified. Any incomplete documents, or missing information that was not recorded at the time of that lab, now need to be checked and included at this stage.

Step 3: Organize the information
A project proposal typically contains the following sections:
Section
Description
Executive Summary
Discusses the project goals and project scope at a high level. This section demonstrates that the network vendor understands the extent of the project and the role of the network in meeting the business goals. The goal of the summary is to convince the decision-makers of the business benefits of the design. This section is typically one to two pages long.
Network Requirements
Reviews the business goals and network requirements, including users and applications that need to be supported. This section often lists the business goals, in order of priority, with critical goals marked. This section includes the topologies; protocols, hardware, software, and training that are required to meet the business goals.
Current Network Environment
Documents the state of the existing network. This section includes physical and logical diagrams and the IP addressing scheme. The section summarizes the results of the network characterization, including strengths and weaknesses of the existing network. It also documents the user community and applications currently in use, based on the network characterization.
Proposed Physical Design
Describes the physical layout of the proposed design. This section
documents trade-offs made to accommodate business goals and technical requirements. The section describes the features and recommended uses for the technologies and devices proposed for the new network design. This section documents the new WAN service and new network equipment. The section also includes proposed network diagrams.
Proposed Logical Design
Describes the logical topology of the proposed network. This section
documents any proposed addressing and naming conventions. It describes the routing and switching protocols recommended for the planned network. This section includes recommended security mechanisms and products that support the security policy of the business. The section may include information on recommended network management procedures and applications.
Implementation Plan
Provides a detailed list of the tasks that must be performed to install and implement the new network. This section includes tasks, steps, time required, and proposed schedules.
Cost Proposal
Provides cost proposal for equipment, software, installation, and ongoing

Step 4: Edit and finalize the information
a. Review all the materials to ensure that they are complete. It is important that the FilmCompany   management and technical staff are able to easily find and understand the material contained in the proposal. A disorganized or incomplete proposal can cause the customer to choose another contractor to complete the project.
b. Ensure that all the information has a consistent format and style. If necessary, edit or rewrite sections so that the proposal has the appearance of a single document and not a set of separate documents.
c. Complete diagrams and other graphics and finalize what is to be included in the proposal.
d. Clearly note those sections of the proposal that have to be completed; these sections will be compiled in the following labs.
e. Save the word processing documents and file the hardcopy information in your portfolio.

Lab 9.2.1 Creating an Implementation Plan

Step 1: Determine the tasks to implement the network design
Implementing a network design requires the completion of a set of tasks, such as installing hardware,
configuring systems, testing the network, and launching the network into production. Each task consists of several steps.
Each task requires the following documentation:
  • A description of the task
  • References to design documents
  • Detailed implementation guidelines
  • Detailed rollback guidelines in case of failure
  • The estimated time required for implementation
  • Completion sign-off
Analyze the FilmCompany network design documentation that you have compiled in previous labs. Determine and list the three main sets of tasks required to be performed to implement the network upgrade. These sets of tasks will be referred to as phases.
Phase 1
_______ Install Distribution and Core Layer equipment
_______ Configure new IP addressing & VLAN scheme
_______ Configure routing
Phase 2
_______ Upgrade the WAN connectivity
_______ Extend the network to the remote site
_______ Configure ACLs & security
Phase 3
_______ Install wireless/mobility network

Step 2: Note identified success and failure criteria
When implementing a design, the possibility of a failure must be considered – even after a successful pilot or prototype network test. Each step of the implementation may require additional testing to ensure that the network operates as designed.
In the Reflection section in Chapter 2, Lab 2.3.3, you considered success criteria when determining the
objectives of the FilmCompany network upgrade. List two or three success or failure criteria for each phase of the project.
Phase 1
_______
_______
_______
Phase 2
_______
_______
_______
Phase 3
_______
_______
_______

Step 3: Include provision for customer approval
The Implementation Plan details the work required to accomplish the project goals. The plan includes the
customer expectations and the success criteria for customer approval and project sign-off. As soon as customer approval of the implementation plan is obtained, the installation can begin. The customer is given a detailed list of all devices required and the work to be completed. This list forms part of the Implementation Plan. A signed copy of this list is kept by the network designer and account manager.
Upon completion of each task, the customer is required to sign off that the work was completed and that the results are as expected.
a. Include in the documentation a signature page for an authorized FilmCompany representative to sign
and approve the Implementation Plan.
b. Include in the documentation a signature page at the end of each task for an authorized
FilmCompany representative to sign and accept the completion of each task.

Step 4: Document Phase 1

Step 5: Document Phase 2

Step 5: Document Phase 3

Lab 9.2.2 Creating a Phased Installation Plan

Step 1: Compare the installation methods
There are three possible installation methods:
  • New installation, commonly referred to as a green field installation
  • Phased installation into an existing, functioning network
  • Complete replacement, commonly referred to as a fork-lift upgrade
Consider and list the advantages and disadvantages of the three installation methods.
New Installation

Advantages:
Semua peralatan dan layanan dapat diinstal dan diuji pada saat yang sama.
Rencana implementasi untuk jaringan baru kurang kompleks dibandingkan dengan dua jenis instalasi.
Jadwal lebih fleksibel daripada ketika jaringan yang ada di tempat.
Ada gangguan minimal terhadap perusahaan.
Disadvantages:
Modal besar karena semua peralatan dan layanan yang diinstal pada waktu yang sama.
Phased Installation into Existing Network
Advantages:
Bagian-bagian dari upgrade jaringan diimplementasikan dalam isolasi dari bagian yang sedang berjalan.
Upgrade jaringan dibagi menjadi potongan-potongan kecil yang dapat diinstal dan diuji dengan cepat.
Instalasi upgrade secara bertahap yang lebih kecil menyebabkan sedikitnya jumlah downtime.

Disadvantages:
Sebuah penerapan secara bertahap membutuhkan perencanaan yang lebih rinci dengan pelanggan.
Complete Network Replacement

Advantages:
Jaringan yang ada bisa tetap beroperasi sepenuhnya sampai jaringan pengganti dibawa ke dalam produksi.

Disadvantages:
Kedua jaringan mungkin beroperasi secara paralel untuk beberapa waktu, yang meningkatkan biaya operasi dan dapat menyebabkan kebingungan dan dukungan bagi pemakai

Step 2: Select the installation method
Two of the FilmCompany requirements are:
  • The company network services must be available during the upgrade.
  • Existing equipment must be used in the new network design.
Select the appropriate installation approach for the FilmCompany network upgrade.
Pendekatan instalasi bertahap akan digunakan untuk proyek ini

Step 3: Complete the details for the installation phases
Using the charts created in Lab 9.2.1; fill out the information for each of the Installation Phases.
a. On the table created in Lab 9.2.1 for Phase 1, fill in the Task/Step, Description, and Implementation Details information:
  • Install Distribution and Core Layer equipment
  • Configure new IP addressing & VLAN scheme
  • Configure routing
b. On the table for Phase 2, fill in the Task/Step, Description, and Implementation Details information:
  • Upgrade the WAN connectivity
  • Extend the network to the remote site
  • Configure Access Control Lists & security
c. On the table for Phase 3, fill in the Task/Step, Description, and Implementation Details information:
Install and configure the wireless and associated mobility network equipment


Lab 9.2.3 Creating a Timeline

Step 1: List and prioritize the factors affecting the timeline
Note issues such as equipment and material availability, skilled personnel, and customer requirements that should be considered for the following factors when developing a project timeline. Consider the possibility that the project might not begin on the proposed start date.
Equipment order and delivery
Service installation, such as WAN links
Customer schedule, including available maintenance and downtime windows
Availability of appropriate technical personnel

Step 2: Complete the time details for each installation phase
The FilmCompany network upgrade is linked to the StadiumCompany network redevelopment. It would be efficient to align the FilmCompany stadium remote site work with that project. The StadiumCompany RFP states that the project must be completed during the off-season for the two teams. This requirement gives the project a timeline of four months, which can be also applied to the FilmCompany upgrade.
a. On the table created in Lab 9.2.1 for Phase 1, fill in the Date information:
  • Install Distribution and Core Layer equipment
  • Configure new IP addressing & VLAN scheme
  • Configure routing
b. On the table for Phase 2, fill in the Date information:
  • Upgrade the WAN connectivity
  • Extend the network to the remote site
  • Configure Access Control Lists & security
c. On the table for Phase 3, fill in the Date information:
  • Install and configure the wireless and associated mobility network equipment

Step 3: Consider customer-caused delays
Customers may make changes to the requirements during the installation of a project. When changes occur, the timeline is used to make adjustments to personnel and other available resources. The timeline
documentation can also be used to show the customer how delays affect the project completion date.
Based on the timeline, write a project variation statement showing the possible delay in the project completion date if the FilmCompany decided at this stage to relocate an additional three production staff and their workstations to the stadium.

Step 4: Using project management software (Optional)
Project management tools such as Microsoft Project can be used to create a project timeline. This software can be useful for:
  • Tracking the progress of the project
  • Keeping the project on schedule
  • Identifying milestones
  • Tracking labor assignments and costs
  • Alerting the designer if the project is falling behind schedule.
If this software is available, enter the resources and timeline for one phase of the Implementation Plan and examine the output.

Lab 9.2.4 Creating an Installation Schedule

Step 1: List and prioritize the tasks that require downtime on the current network
List the tasks that require network downtime.

Step 2: Document the required downtime on the project timeline
Sometimes it is not possible to complete all of the required tasks during an approved maintenance window. If an installation task requires the network, or part of the network, to be down during normal business hours, it is important to obtain permission from the customer. As soon as the time frame is determined and approved, all the people involved need to be notified accordingly.
a. List those tasks that can be completed during a scheduled maintenance window.
b. List those tasks that require the network to be down during normal business hours.

Step 3: Document customer approved downtime
a. Indicate on the Installation Plan Timeline when the network downtime will occur.
b. Include a provision for customer approval to be recorded for this downtime.
c. Include a task that requires that the users who will be affected are notified with adequate advance notice of the network downtime. Ensure that the users are also notified when the network or service returns to full operation.

Lab 9.3.4 Creating the Bill Of Material

Step 1: List the items required
a. Use the table below, or create a similar one, to list all the items and equipment that need to be purchased for the FilmCompany network upgrade project.
b. Search the Internet or use information provided by your instructor to add possible suppliers or vendors to the BOM table.
c. Add costs to the BOM. Where possible, obtain costs from local vendors and suppliers. If this information is not readily available, your instructor will provide estimated costs for you to use.

Step 2: Determine the software requirements
a. During the early stages of the network Design Phase, existing applications were identified. Add new applications required by the network upgrade to the BOM. Categorize these as either Network or Specialist applications.
b. Add the new applications, installation costs, and required training to the BOM with the identified hardware. Also indicate whether the network upgrade requires additional licenses to be purchased for existing software applications.

Step 3: Add maintenance contracts
a. Investigate the maintenance support service contracts available for both the new and existing equipment.
b. Add the details and costs to the BOM.

Step 4: Create the BOM
a. Create the BOM using word processing or spreadsheet software. Using a spreadsheet will facilitate the calculation of total costs and enable easy updating of the document if costs or quantities are amended.
b. Save this file and include it in the proposal document. Add a hardcopy of the file to your portfolio.

ab 9.4.1 Compiling the Documentation

Task 1: Compile the Project Proposal

Step 1: Finalize the documentation requirements
a. Finalize the documentation created in the previous labs and in your project portfolio.
b. Insert and compile the information under the following headings:
  • Executive Summary
  • Network Requirements
  • Current Network Environment
  • Proposed Physical Design
  • Proposed Logical Design
  • Implementation Plan
  • Cost Proposal
Step 2: Prepare the cover page
Include a cover page at the beginning of the proposal. The cover page describes the proposal, including the RFP or solicitation number and date, the customer contact information, and the vendor name and contact information.

Step 3: Prepare the Table of Contents
Develop a Table of Contents for the proposal document.

Step 4: Create the proposal
Complete the proposal document. The proposal layout should be highly readable and should aid the reader in locating information.
  • Use graphics to enhance the readability of a proposal and convey information where appropriate.
  • Text should be legible, typically a serif typeface such as Times Roman, at 10-point to 12-point type.
  • Page margins should be at least 0.5 inches (125mm).
  • Page numbers should be included at the top or bottom of each page.
Step 5: Update the Executive Summary
Use information from the completed implementation and costing sections to update the Executive Summary.

Step 6: Organize the Proposal binder
Arrange the proposal components in a binder, based on the order cited in the Table of Contents.

Step 7: Prepare Terms and Signatures page
a. Prepare the terms of agreement and an acceptance page for customer signatures to be included at
the end of the proposal. The terms and conditions describe all relevant legal terms and contracts that
will be required. These terms and conditions support the supply of goods and services related to
network improvements and installations.
Important clauses in the terms and conditions usually include:
  • Details about the proposal expiration date
  • Obligations of the customer to obtain permission or other consents within their organization
  • Obligations of the vendor to provide services and equipment with care and skill
  • Dates when completed milestone deliverables are payable
  • Interest chargeable on outstanding payments
  • The amount of notice the customer must give to cancel their equipment and service orders
  • Details about guarantees (if any) provided by the vendor
  • Details about escalating and resolving complaints or issues
If the customer accepts the proposal, an appropriate customer representative signs the Terms and
Signatures page.
Your instructor will advise of the standard terms and conditions that will apply to all proposals.
b. Save this file and include in the proposal document.


Task 2: Prepare the Presentation

Step 1: Plan the presentation
After compiling a proposal, network designers review the entire proposal with their management organization by means of a formal presentation. During this stage of the design proposal, the designer must first sell the concept to the internal management and then to the customer.
For your presentation, list the important points to include that illustrate the proposal. A proposal presentation includes slides or other visual aids to graphically represent the proposal. The presentation, along with the proposal document, is vital to ensuring a successful meeting and increasing the probability of a customer sign-off.

Step 2: Create the presentation
This step assumes that the presentation will use MS PowerPoint or equivalent presentation software. Your instructor will advise of the presentation requirements and resources available.
a. The content and presentation format are important in a business environment. Create a presentation
that considers the following points:
  • Every slide should have a heading that summarizes the information presented on the slide.
  • Computer presentations should not contain full paragraphs of text. Use a bulleted list or outline format and elaborate on the points during the delivery.
  • All type should be legible. Use large fonts, because small fonts are often hard to read.
  • Use contrasting colors – either a dark background with light text or a light background with dark text.
  • Keep the format and style consistent throughout the presentation. Do not change text font, text color, background color, or theme except for an occasional special emphasis.
  • Avoid backgrounds that make the text hard to read. Keep the background simple.
  • Do not use ALL CAPS! Their use is unprofessional and they are also more difficult to read.
  • Include a combination of words, pictures, and graphics. Variety keeps the presentation interesting.
b. Save the presentation file and any other presentation aids that you created.

Lab 9.4.2 Presenting the Project Proposal

Task 1: Prepare for the Presentation

Step 1: Review the content
a. Ensure that your presentation is complete.
b. Review the content to ensure that there are no technical errors.
c. Rehearse the presentation to become familiar with the flow of the content and develop a sense of the timing required.

Step 2: Prepare for questions
Your presentation may seem complete and clear to you, but to others there may be points that need clarifying or that contain too much information.
Read through your presentation as if seeing it for the first time, Note the points that you would ask questions about. Remind yourself that you will not be able to prepare for every possible question.

Step 3: Prepare yourself
Your instructor will advise you on the details (time. location, audience) of the presentation class. On the day of the presentation, try to observe the following guidelines:
a. If possible, and appropriate, wear professional attire.
b. Try not to be too nervous. The other students in your class are probably feeling the same as you are.
c. If other students are presenting before or after you, give them your attention and participate in the class. Do not think too much about your presentation but focus instead on what is happening in the class.


Task 2: Deliver the Presentation

Step 1: Submit your portfolio and proposal
a. Submit your portfolio and proposal to your instructor before delivering the presentation.

Step 2: Begin the presentation
a. Introduce yourself.
b. Deliver the presentation, using your portfolio and a slide presentation such as PowerPoint.
  • Speak slowly and clearly.
  • Stay with your slide sequence. A common mistake is to introduce material and then continue to talk about it in detail without advancing from the general overview slide for that topic to the detailed slides that follow.
c. Demonstrate that you know the content of the proposal and sell it as the one that the customer should adopt.
d. Be prepared to respond to questions from the instructors and students.

Step 3: Conclude the presentation
a. Invite any final questions from the audience.
b. Finish your presentation by assuring the audience that your proposal meets their requirements and thank them for the opportunity to present it.

Can the serial interface on Router2 be pinged from Router1? ____ Ya
Can the serial interface on Router1 be pinged from Router2? ____ Ya
If the answer is no for either question, troubleshoot the router configurations to find the error.
Then issue the pings again until the answer to both questions is yes.

Step 8: Configure PPP authentication on R1 with CHAP
a. Configure the CHAP username and password on the R1 router. The username must be identical to
the hostname of the other router. Both the password and usernames are case-sensitive. Define the
username and password to expect from the remote router. On Cisco routers, the secret password
must be the same for both routers.
Router1(config)#username Router2 password cisco
Router1(config)#interface serial 0/1/0
Router1(config-if)#ppp authentication chap
Router1(config-if)#end
Router1#

Step 9: Configure PPP authentication on R2 with CHAP
a. Configure the CHAP username and password on the R2 router. The passwords must be the
same on both routers. The username must be identical to the hostname on the other router. Both
the password and user names are case-sensitive. Define the username and password to expect
from the remote router.
Router2(config)#username Router1 password cisco
Router2(config)#interface serial 0/1/1
Router2(config-if)#ppp authentication chap
Router2(config-if)#end
Router2#

Step 10: Verify that the serial connection is functioning
Verify that the serial connection is functioning by pinging the serial interface of R1.
Was it successful? __________ yes
Router2#ping 192.168.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 28/28/28 ms
Why or why not?
Kedua router menggunakan PPP dengan CHAP dan username yang sesuai dan password diatur pada kedua router.

Step 12: Clean up
a. Erase the configurations and reload the routers.
b. Disconnect and store the cabling.
c. For PC hosts that are normally connected to other networks (such as the school LAN or to the
Internet), reconnect the appropriate cabling and restore the TCP/IP settings.

Lab 8.3.2 Creating a VPN Connectivity Test Plan

Step 1: Review the VPN Design Test Plan
Review the VPN Design Test Plan. Note the tests that the designer indicates are necessary to perform using the prototype network.

Test 1: Description and purpose:
EasyVPN Server Setup Verifikasi

Test 2: Description and purpose:
Konektivitas Test Klien VPN

Step 2: Review the Equipment section
Which device will be used as the VPN server in the prototype network? 1841 Router
What IOS version is necessary to configure the EasyVPN server? Advanced Layanan IP versi 12,4 atau di atas dan Cisco SDM
Is equipment available in your lab with the correct IOS to build the prototype network configuration?

Step 3: Review the Design and Topology section
At the top of this lab, the actual VPN topology is shown, as well as the topology being used in the prototype test. Compare both topologies. Remote workers usually connect to the Internet and then use client software to create the VPN tunnel to the server. In the prototype environment, the connection between the VPN client and the VPN server is a much more direct connection.
What is the risk of testing the VPN operation in a prototype environment?
Kondisi dunia nyata tidak dapat dengan mudah disimulasikan. Server VPN akan memberikan alamat logis ke remote host H1 yang berlaku di jaringan internal. Alamat ini akan ditugaskan secara dinamis, ketika terowongan VPN dibuat.

Step 4: Review the Test 1 Description, Procedures, and Expected Results sections
The designer needs to verify that the EasyVPN server can be configured and managed by the existing
personnel. It is important to document how the Cisco SDM software can be used to configure and manage the VPN server.

Step 5: Review the Test 2 Description, Procedures, and Expected Results sections
Read through the Test 2 information in the test plan. Determine an appropriate goal for Test 2 and fill in the table in the VPN Design Test Plan.
After reading the Procedures section, what do you think would be a successful outcome of completing the
Test 2 procedures?
Successful connection to the VPN server using the external VPN client
Successful tunnel establishment
VPN client has received an internal IP address from the VPN server.
VPN client can ping an internal host or connect to an internal server service
Record your answers in the Expected Results and Success Criteria section for Test 2.
Reflection / Challenge
Why do you think it is important to test the VPN operation in a pilot installation, as well as a prototype test?
Implementasi pilot dapat menguji konfigurasi dan operasi dalam lingkungan dunia nyata.
What are the benefits of managing the VPN server with internal personnel, rather than using the ISP to manage it?
Hal ini lebih fleksibel. Mengurangi biaya. Lebih mudah untuk menambahkan klien tambahan.

Lab 8.2.6 Evaluating the Prototype Test

 

Step 1: Identify if weaknesses are present in the design
Is the Frame Relay WAN design able to scale to meet the expected growth?
Ya, layanan Frame Relay biasanya sangat terukur. CIR tambahan dapat dibeli dan sirkuit tambahan dapat ditambahkan jika diperlukan.

Do the results of the prototype test indicate that the Frame Relay configuration will work as expected?
Karena sebuah router bertindak sebagai saklar Frame Relay simulasi, tidak ada cara untuk menguji bandwidth dan kinerja Frame Relay nyata switched jaringan. Karena tidak mungkin untuk menguji kemampuan melalui jaringan Frame Relay TSP sebenarnya ada risiko yang berkaitan dengan desain.
Are there any weaknesses associated with using the VPN connections as backup to the Frame Relay WAN?
Walaupun pengujian memverifikasi bahwa fungsi Ethernet berbasis simulasi backup, ini tidak cukup mensimulasikan penggunaan link VPN sebagai link Fast Ethernet jauh lebih cepat daripada VPN khas. Daerah yang paling kritis risiko adalah kinerja dari link VPN sebagai backup dalam jaringan nyata. Apabila komponen suara dan video dari jaringan ditambahkan ke WAN lalu lintas yang ada, mungkin ada masalah kualitas layanan jika koneksi VPN harus digunakan. VPN arus melalui ISP tidak memiliki tingkat jaminan pelayanan. Selain itu, tidak memiliki mekanisme untuk menyediakan QoS. Akibatnya, link cadangan hanya bisa menyediakan konektivitas terbatas dalam hal kegagalan.

Will a failure of the primary link cause the FilmCompany to lose connectivity to the Stadium LAN?
Tidak, link backup dengan rute statis mengambang akan diaktifkan untuk menyediakan konektivitas ketika F primer / link R gagal.

Does the EIGRP authentication provide for a secure transmission of the routing updates?
Ya, meskipun penggunaan Pesan Digest 5 (MD5). Kombinasi kunci pengenal dan antarmuka yang terkait dengan pesan unik mengidentifikasi algoritma otentikasi dan kunci MD5 otentikasi digunakan.

Step 2: Determine what the risks are of not correcting the weaknesses
If, in Step 1, you identify weaknesses in the proposed design, what risks do these weaknesses present to
FilmCompany?
Risikonya adalah bahwa jaringan Frame Relay bawah beban aktual pengguna yang sebenarnya tidak akan melakukan serta link disimulasikan dalam prototipe. Juga, link VPN cadangan disimulasikan mungkin tidak bekerja seperti yang diharapkan dalam hal pemulihan menggunakan link VPN nyata bukan link FastEthernet simulasi. Penerimaan akhir dari desain mungkin harus menunggu sampai hasil instalasi pilot diketahui.

Step 3: Suggest ways that the design can be improved to reduce the risk
In what ways could the proposed design be improved to reduce the areas of risk?
Jika waktu dan uang mengizinkan, uji coba dapat dijalankan di mana sirkuit F/R sementara dengan CIR tertentu bisa dipasang dengan kerjasama layanan yang disediakan dan beban uji simulasi dapat dihasilkan pada berbagai waktu untuk memastikan kinerja di bawah tinggi -volume kondisi. Tingkat perjanjian layanan (SLA) juga bisa dinegosiasikan untuk menyediakan asuransi yang rangkaian akan bekerja seperti yang diharapkan selama periode beban puncak. Sehubungan dengan link backup VPN, pilot dapat termasuk penggunaan koneksi VPN aktual melalui link DSL ke lebih akurat menunjukkan kemampuan pemulihan dari desain yang diusulkan.

Step 4: Document the weaknesses and risks on the test plan
In the Results and Conclusions section of the test plan, record any weaknesses, risks, and suggested improvements.

Step 4: Reflection
Why do you think it is important to identify weaknesses and risks in the proposed design before presenting it to the customer? What are some reasons that weaknesses cannot be corrected?
Adalah penting untuk mengidentifikasi kelemahan dan risiko dalam desain yang diusulkan sebelum menyajikannya kepada pelanggan untuk memastikan bahwa pelanggan memahami keterbatasan prototipe dan tidak mengarah pada memiliki harapan yang tidak realistis berdasarkan prototipe. Mungkin tidak mungkin untuk mengimbangi semua kelemahan yang dapat diidentifikasi karena waktu, uang atau kendala personil. Risiko harus dianalisa dan seimbang terhadap variabel-variabel lainnya.
