How To Create a PERT Chart

The PERT chart shows the logical connections and consequence of a set of tasks. PERT charts the time period for problem solving and the implementation plan for all activities along the critical path. The PERT chart is also known as a precedence diagram or project network diagram.
"The Program (or Project) Evaluation and Review Technique, commonly abbreviated PERT, is a statistical tool, used in project management, that is designed to analyze and represent the tasks involved in completing a given project. ...
PERT is a method to analyze the involved tasks in completing a given project, especially the time needed to complete each task, and to identify the minimum time needed to complete the total project.
PERT was developed primarily to simplify the planning and scheduling of large and complex projects. ...
A network diagram can be created by hand or by using diagram software. There are two types of network diagrams, activity on arrow (AOA) and activity on node (AON). Activity on node diagrams are generally easier to create and interpret." [Program Evaluation and Review Technique. Wikipedia]
The PERT chart is one of the Seven Management and Planning Tools (7 MP tools, Seven New Quality Tools).
The PERT chart template for the ConceptDraw PRO diagramming and vector drawing software is included in the solution "Seven Management and Planning Tools" from the Management area of ConceptDraw Solution Park.

"A project network is a graph (flow chart) depicting the sequence in which a project's terminal elements are to be completed by showing terminal elements and their dependencies.
... the project network shows the "before-after" relations.
The most popular form of project network is activity on node, the other one is activity on arrow.
The condition for a valid project network is that it doesn't contain any circular references." [Project network. Wikipedia]

"Solution selling is a sales methodology. Rather than just promoting an existing product, the salesperson focuses on the customer's pain(s) and addresses the issue with his or her offerings (product and services). The resolution of the pain is what constitutes a "solution". ...
Followers of "solution-selling" generally apply a consultative sales approach to all aspects of their sales process (or during a sales cycle) including:
Prospecting;
Diagnosing customer needs;
Crafting a potential solution;
Establishing value;
Bargaining for access to decision-makers;
Positioning proof, ROI and the total solution;
Negotiating a win-win solution;
Following up to ensure customer success.
The solution selling methodology has evolved as key components of professional selling evolve. As a result, solution selling has become more broadly defined - to include dimensions of "sales process", "competitive selling", "value selling" as well as "consultative selling" or "complex selling" which set the focus on the team's aspects of the sales."

The PERT chart example "Sale problem solution" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the solution Seven Management and Planning Tools from the Management area of ConceptDraw Solution Park.

"A request for proposal (RFP) is a solicitation made, often through a bidding process, by an agency or company interested in procurement of a commodity, service or valuable asset, to potential suppliers to submit business proposals. It is submitted early in the procurement cycle, either at the preliminary study, or procurement stage. The RFP process brings structure to the procurement decision and is meant to allow the risks and benefits to be identified clearly up front.
The RFP presents preliminary requirements for the commodity or service, and may dictate to varying degrees the exact structure and format of the supplier's response. Effective RFPs typically reflect the strategy and short/ long-term business objectives, providing detailed insight upon which suppliers will be able to offer a matching perspective.
Similar requests include a request for quotation and a request for information.
In principle, an RFP:
(1) informs suppliers that an organization is looking to procure and encourages them to make their best effort.
(2) requires the company to specify what it proposes to purchase. If the requirements analysis has been prepared properly, it can be incorporated quite easily into the Request document.
(3) alerts suppliers that the selection process is competitive.
(4) allows for wide distribution and response.
(5) ensures that suppliers respond factually to the identified requirements.
(6) is generally expected to follow a structured evaluation and selection procedure, so that an organization can demonstrate impartiality - a crucial factor in public sector procurements." [Request for proposal. Wikipedia]
