Process Engineering Quarter (hereinafter, the Quarter) is the first of four lectures of Effort Quadrivium (hereinafter, the Quadrivium):

The Quadrivium is the first of seven modules of Septem Artes Administrativi, which is a course designed to introduce its learners to general concepts in business administration, management, and organizational behavior.


Outline

The predecessor lecture is Controlling Quarter.

Concepts

  1. Process engineering.
    • Engineering. The application of scientific principles to practical ends.
  2. Process. An action that individuals, groups, and organizations engage in as a result of inputs and that leads to certain outputs.
    • Process. A set of activities used to convert inputs into desired outputs.
    • Process. simply the way someone works. Everyone has a process. It can be pre-defined, empiric or merely chaotic.
    • Business process. A set of defined ad-hoc or sequenced collaborative activities performed in a repeatable fashion by an organization. Processes are triggered by events and may have multiple possible outcomes. A successful outcome of a process will deliver value to one or more stakeholders.
    • Input. A variable that leads to processes.
      1. Input. A material, service or support item that is processed by the system.
    • Output. An immediate and direct result of a process.
    • Outcome. A key factor that is affected by some other variables.
    • Organizational process asset. All materials used by groups within an organization to define, tailor, implement, and maintain their processes.
    • Technique. Techniques alter the way a business analysis task is performed or describe a specific form the output of a task may take.
    • Cycle. refers to the total amount of time it takes for a single task or work item to travel through the workflow from the beginning of work until it ships.
  3. Production.
    • Process production. The production of items in continuous process.
    • Unit production. The production of items in units or small batches.
    • Production environment. A term describing the setting where a product is put into use by customers on a regular basis.
    • Operational support. A stakeholder who helps to keep the solution functioning, either by providing support to end users (trainers, help desk) or by keeping the solution operational on a day-to-day basis (network and other tech support).
  4. Activity. Any enterprise effort performed as part of a project or operations. An activity shall have its own name and description; most often, they have one or more predecessor activities and successor activities. Planned activities may have their expected input resources, process assets, time frames, and costs; completed activities may have their actual data. Activities may be subdivided into tasks.
    • Activity diagram. A model that illustrates the flow of processes and/or complex use cases by showing each activity along with information flows and concurrent activities. Steps can be superimposed onto horizontal swimlanes for the roles that perform the steps.
    • Workflow diagram. A graphical representation of activities and actions conducted by users of a system. (Sometimes called an activity diagram.)
  5. Process model. A visual model or representation of the sequential flow and control logic of a set of related activities or actions.
    • Swimlane. The horizontal or vertical section of a process model that show which activities are performed by a particular actor or role.
    • Slack time. The amount of time an individual activity can be delayed without delaying the whole project.
    • Process map. A business model that shows a business process in terms of the steps and input and output flows across multiple functions, organizations, or job roles.
    • Relationship map. A business model that shows the organizational context in terms of the relationships that exist among the organization, external customers, and providers.
    • Relationship. A defined association between concepts, classes or entities. Relationships are usually named and include the cardinality of the association.
    • Entity-relationship diagram. An entity-relationship diagram is a graphical representation of the entities relevant to a chosen problem domain, the relationships between them, and their attributes.
    • Dependence. B's relationship to A when A possesses something that B requires.
    • Red route. The frequent and critical activities that users will perform on your site. They are complete activities, not single tasks, and will probably require several pages to execute. Defining the red routes for your site means that you’ll be able to identify and eliminate any usability obstacles on the key user journeys. (Important roads in London are known as ‘red routes’ and Transport for London do everything in their power to make sure passenger journeys on these routes are completed as smoothly and quickly as possible.)
  6. System. A set of interrelated and interdependent parts arranged in a manner that produces a unified whole.
    • System. A collection of interrelated elements that interact to achieve an objective. System elements can include hardware, software, and people. One system can be a sub-element (or subsystem) of another system.
    • System. A set of interrelated components working together to produce a desired result.
    • Mission. An undertaking that is supported by the system to be designed to be successful (e.g. space mission).
    • Open system. A system that interacts with its environment.
    • Closed system. A system that is not influenced by and does not interact with its environment.
    • External interface. An interface with other systems (hardware, software, and human) that a proposed system will interact with.
    • Boundary. A separation between the interior of a system and what lies outside.
    • Context diagram. An analysis model that illustrates product scope by showing the system in its environment with the external entities (people and systems) that give to and receive from the system.
      1. Context. The users, other systems and other features of the environment of the system that the system will interact with.
  7. Business event. A system trigger that is initiated by humans.
    • Event. An event is something that occurs to which an organizational unit, system, or process must respond.
    • Temporal event. A system trigger that is initiated by time.
    • Event response table. An analysis model in table format that defines the events (i.e., the input stimuli that trigger the system to carry out some function) and their responses.
  8. Feedback. Information about the output of a system that can be used to adjust it.
    • Feedback. The degree to which carrying out the work activities required by a job results in the individual obtaining direct and clear information about the effectiveness of his or her performance.
    • Feedback. The degree to which carrying out work activities required by a job results in the individual's obtaining direct and clear information about her or his performance effectiveness.
    • Output. What is produced by a system.
    • Desired outcome. The business benefits that will result from meeting the business need and the end state desired by stakeholders.
  9. Systems engineering. The orderly process of bringing a system into being using a systems approach.
    • Systems approach. The application of a systematic disciplined engineering approach that considers the system as a whole, its impact on its environment and continues throughout the lifecycle of a project.
    • System design. The identification of all the necessary components, their role, and how they have to interact for the system to fulfill its purpose.
    • System integration. The activity of integrating all the components of a system to make sure they work together as intended.
    • Human factor. Also called ergonomics. The scientific discipline of studying interactions between humans and external systems, including human-computer interaction. When applied to design, the study of human factors seeks to optimise both human well-being and system performance.
    • Interdisciplinarity. People from different disciplines working together to design systems.
    • Specifications. The technical requirements for systems design.
    • Datapoint-device architecture.
    • Object-oriented modeling. An approach to software engineering where software is comprised of components that are encapsulated groups of data and functions which can inherit behavior and attributes from other components; and whose components communicate via messages with one another. In some organizations, the same approach is used for business engineering to describe and package the logical components of the business.
  10. Quality assurance (QA). (1) Enterprise efforts undertaken in order to evaluate overall performance within processes on a regular basis to provide confidence that the deliverables will satisfy the requirement specifications, customer expectations, and relevant quality standards. In other words, quality assurance include the activities performed to ensure that a process will deliver products that meet an appropriate level of quality; (2) The organizational unit that is assigned responsibility for quality assurance.

Roles

Methods

  1. Precedence diagramming method (PDM). A network diagramming technique in which activities are represented by boxes (or nodes). Activities are linked by precedence relationships to show the sequence in which the activities are to be performed.
  2. Program Evaluation and Review Technique (PERT). An event-oriented network analysis technique used to estimate program duration when there is uncertainty in the individual activity duration estimates. PERT applies the critical path method using durations that are computed by a weighted average of optimistic, pessimistic, and most likely duration estimates. PERT computes the standard deviation of the completion date from those of the path's activity durations.
  3. Critical path method (CPM). A network analysis technique used to predict project duration by analyzing which sequence of activities (which path) has the least amount of scheduling flexibility (the least amount of float). Early dates are calculated by means of a forward pass, using a specified start date. Late dates are calculated by means of a backward pass, starting from a specified completion date (usually the forward pass' calculated project early finish date).
    • Critical path. The series of activities that determines the duration of the project. In a deterministic model, the critical path is usually defined as those activities with float less than or equal to a specified value, often zero. It is the longest path through the project. See critical path method.
    • Critical activity. Any activity on a critical path. Most commonly determined by using the critical path method. Although some activities are "critical," in the dictionary sense, without being on the critical path, this meaning is seldom used in the project context.
  4. Six Sigma. A quality program designed to reduce defects and help lower costs, save time, and improve customer satisfaction.
  5. DevOps. Practice and a set of concepts, based on that practice, that define culture of unifying software development (Dev) and software operations (Ops). Its signature toolchain represents a chain of tools that fit one of the following categories: (a) Code, (b) Build, (c) Test, (d) Package, (e) Release, (f) Configure, and (e) Monitor.
  6. Process consultation. A meeting in which a consultant assists a client in understanding process events with which he or she must deal and identifying processes that need improvement.

Instruments

  1. Flowchart software.
  2. Big visible chart. A large chart displayed near the Agile team that show how the team is progressing. You could make a big visible chart to show defects, velocity (burndown chart), customer acceptance tests, or to find out how much time the team is wasting.
    • Burndown chart (or Burndown chart). The chart that represents all outstanding work. The vertical axis represents the backlog, while the horizontal axis represents time. The work remaining can be represented by story points, ideal days, team days, or other metrics.
    • Burnup chart (or Burnup chart). The chart that tracks how much work has been completed. There are two lines on the chart—one line represents total work and the other represents work completed. The vertical axis represents the amount of work and can be measured in number of tasks, hours, or story points. The horizontal axis represents time, usually measured in days.
  3. Linear programming. A mathematical technique that solves resource allocation problems.
