2.2.1 Sales Activities and the Role of the Network Designer in the Pre-Sales Process

Response document:

  • Cover letter

  • Executive summary

    • Overview, Solution, Why choose our firm…

  • Proposed solution and proposed cost

  • Signature page

  • Appendices


2 2 1 sales activities and the role of the network designer in the pre sales process1

2.2.1 Sales Activities and the Role of the Network Designer in the Pre-Sales Process

  • Customer issues RFP or RFQ

  • Pre-bid meeting or pre-submittal conference

    • An opportunity to review the project scope with the customer

    • Additional information and documentation identified, but not included in the original RFP

    • Clarification of formatting and project timeline details not included in the original RFP


2 2 3 sales activities and the role of the network designer in the pre sales process

2.2.3 Sales Activities and the Role of the Network Designer in the Pre-Sales Process

Request for Proposal (RFP):

  • Business goals

  • Project scope

  • Requirements for new network

  • Preliminary schedule, milestones and deliverables

RFPs and RFQs include specifications that define the format and content of the expected responses from the potential contractors. It is critical for contractors to follow the instructions contained within the document as accurately as possible.

Not following the directions or missing sections of the request could mean that the project is awarded to another contractor.

2.2.4 Sales Activities and the Role of the Network Designer in the Pre-Sales Process

Request For Quote (RFQ): When Technical Specs are Known

  • Organizational overview

  • Required deliverables

  • Assumptions/agreements

2.2.6 Sales Activities and the Role of the Network Designer in the Pre-Sales Process

Pre-sales systems engineer:

  • Determine the need for upgrades or additions by analyzing the network

  • Determine technical requirements and feasibility

Post-sales field engineer:

  • Ensure network upgrade functions as designed

  • Provide customer training and assistance

  • Resolve technical problems


The process of creating a network design and the information needed

The Process of Creating a Network Design and the Information Needed

Interpersonal skills:

  • Listening and accurately summarizing information

  • Corresponding with clients

  • Presenting technical material


The process of creating a network design and the information needed1

The Process of Creating a Network Design and the Information Needed

  • Understand how network users interact with network resources and services

  • Identify all user groups

  • Assess the impact of adding new user groups


2 3 3 the process of creating a network design and the information needed

2.3.3 The Process of Creating a Network Design and the Information Needed

Prioritize the business goals:

  • Profitability

  • Business growth and market share

  • Customer Satisfaction

  • Contribute to the success of the business


2 4 1 identify requirements and constraints to determine the scope of the project

2.4.1 Identify Requirements and Constraints to Determine the Scope of the Project

  • Identify and define the technical requirements


2 4 2 identify requirements and constraints to determine the scope of the project

2.4.2 Identify Requirements and Constraints to Determine the Scope of the Project

  • Identify the constraints that affect the network design, including cost, schedule, and resource constraints

Budget - Limited resources may require some compromises in design due to the costs of equipment, software, or other components.

Company policies - The design must take into account the customer's existing policies regarding protocols, standards, vendors, and applications.

Scheduling - The project time frame should be aligned with the customer schedules.

Personnel - The availability of trained personnel at the implementation and operation phases might be a design consideration.


2 5 1 design considerations for manageability

2.5.1 Design Considerations for Manageability

Top-down design approach:

  • Adapt the network to the needs of the organization

  • Take the design from the perspective of the required network solutions


2 5 2 snmp

2.5.2 SNMP

Typical network management architecture:

  • Network Management System (NMS)

  • Network Management Protocol (SNMP)

  • Managed devices

  • Management agents - software

  • Management information


Design considerations for manageability

Design Considerations for Manageability

  • Network monitoring tools can be used to page or send email to on-call technicians

  • Tools respond to network fault or when a predefined threshold is met


Summary

Summary

  • The six phases of the network lifecycle include prepare, plan, design, implement, operate, and optimize.

  • A project plan includes tasks, timelines, risks, responsibilities, and resources required to complete a network design project.

  • Following the required format and schedule is critical to submitting a successful proposal.

  • All members of the networking contractor staff must demonstrate effective interpersonal skills.

  • Top-down network design strategies have the best chance to succeed.

  • A primary requirement for any network is the availability of qualified support personnel.
