Data Quality

The quality of the information is based on the quality of the basic data with which measurements and indicators are built. As data quality we means complete, with valid values (not null), correct type (eg Date, Number), and is in the proper range (zero to N , a valid date, a valid name).

You can help ensure data quality as follows:

  • By entering certain mandatory fields

  • Monitoring a "data quality index" using the defined indicator. This indicator is calculated for each data import and individual field level obtained as a ratio between the number of field values considered correct vs. the number of values considered incomplete

Process Control

You can monitor the process performance using indicators and measurements, according to their business objectives. These indicators are constructed from basic measurements with high reusability in different contexts and processes: size, effort, reuse, productivity, errors, rework. Have access to a rich set of indicators covering a wide range of processes (management, engineering and process support). Through the use of "process control graphics" can analyze data generated at each iteration of project over time. These graphs allow discrimination "noise" from "signal" using very simple statistical techniques (based on a "normal" distribution, so the data must be "homogeneous"). Given the amount of data available it is important to discriminate information from simple "noise". This can be viewed directly "statistical signal" in the data to determine points in a data series that require "explanation" of its assignable cause variation. These cases are characterized by an unexpected change in the performance of the process. Also known as "assignable causes" because they can be identified, analyzed, and taken into account to prevent recurrence. May be due to:

...

To improve the performance of your processes, the categorization of the variation in the data reported by the indicators is the first step to take. You can discern between different variation patterns, each with its implication including:

  • Points "dominant": a possible signal process (or fault data) that cause an overflow outside the natural statistical limits, given by + - 3 sigma variation from the mean

  • Points "moderate": signal a possible change process that moves the average natural boundary near the bottom or top

  • Points "weak": signal a possible process that causes a shift down, or up, the average

  • Points "near average": a possible signal that keeps the process close to the average performance

  • Points "ascendant": signal a possible change process that moves something the average downward or upward

...

Measurements analyst has all the information necessary to determine past performance, current and future estimated that each indicator provides so we can support better decision-making and continuous improvement of processes available through graphics, rules of pattern analysis variation, filters and other facilities like comparing baseline and extrapolation or comparing individual series. You can access this type of analysis directly from the tools

  • Monitoring a "data quality index" using the defined indicator. This indicator is calculated for each data import and individual field level obtained as a ratio between the number of field values considered correct vs. the number of values considered incomplete

We can create an indicator to monitor this quality index over time, along with detailed data from the associated context for easy review.

The Context

The context is the quantitative / qualitative information associated with a graph / data of an indicator for a project / group in a period of time that gives it meaning and that it must always accompany them in order to be feasible its interpretation. This context is generated automatically by the application.

...

There are several types of context. A type of context, called "Global" is a set of events (dates) on a timeline. A special event is "SourceOrigin" and can be used to filter data from that date. This context is generated and maintained by the user through "Global Notes".

In Improvekit we return to the primordial philosophy of object orientation, which is to be based on mental models. In the framework of the system, we do it using the Activity Systems. Activity theory helps explain how social artifacts and social organization mediate social action.
        
The goal of Activity Theory is understanding the mental capabilities of a single individual. However, it rejects the isolated individuals as insufficient unit of analysis, analyzing the cultural and technical aspects of human actions. Activity theory is most often used to describe actions in a socio-technical system through six related elements of a conceptual system expanded by more nuanced theories:

  • Object-orientedness : the objective of the activity system. Object refers to the objectiveness of the reality; items are considered objective according to natural sciences but also have social and cultural properties.

  • Subject or internalization : actors engaged in the activities; the traditional notion of mental processes

  • Community or externalization : social context; all actors involved in the activity system

  • Tools or tool mediation : the artifacts (or concepts) used by actors in the system. Tools influence actor-structure interactions, they change with accumulating experience. In addition to physical shape, the knowledge also evolves. Tools are influenced by culture, and their use is a way for the accumulation and transmission of social knowledge. Tools influence both the agents and the structure. In improvekit we also consider tools as "edge objects" (entities that can link communities together as they allow different groups to collaborate in a common task)     

  • Division of labor : social strata, hierarchical structure of activity, the division of activities among actors in the system

...

  • system     

  • Rules : conventions, guidelines and rules regulating activities in the system

The data sources, and certain indicators, contain metadata to represent the components of the related activity system, in particular, the instruments, operations and intervening actors.

Activity patterns

Self-constructed graphical formalism which is a socio-technical systemic view that relates the following components in a solution pattern from the signals and other clues in the data:

  • context: the general context present in the story, derived from each indicator.

        Summary For Example:     Summary of the general context:
            Tasks  Tasks with duration exceeded: measure the volume of tasks that exceed the established time limit to determine bottlenecks and corrective actions.
            Task ; Task Type Activity Volume (Monthly) - Measure task size regardless of effort (quarterly).
            Activity ;  Activity Volume: Measure project performance based on estimated task size.

  • the problem (as contradictions / tensions): problems can be expressed as contradictions / tensions in the activity system. The contradictions are entered by the user (a series of possible defaults contradictions derived from the data are suggested, including internal stresses to a component of the system, stresses between two components, due to changes, with other activity systems, or predefined from parameters (such as baseline thresholds, number of actors, roles, workflow, etc.).

        AS For example:    ActivitySystem Tasks with exceeded duration @ Improvement of Processes and Tools
        AS ;  ActivitySystem Task type Activity Volume (monthly) @Improvement of Processes and Tools
        AS ;  ActivitySystem @ Activity Volume Process and Tool Improvement

  • the causes: they are defined based on the patterns detected in the data, such as statistical signals, diffuse signals, etc.

        Tasks For example: Tasks with duration exceeded: measure the volume of tasks that exceed the established time limit to determine bottlenecks and corrective actions.
    Process stability
        Stable :  Stable process Values ​​fluctuate fluctuate around an average of 34.0000 with September 13, 2019 10.0000 and maximum minimum values ​​January January 17, 2020 68.0000. it is not normal distribution. The kurtosis is of the peak type and straight symmetry.
        Patterns
            The :  The values ​​have have a "slightly low" degree of dispersion and "0..2" diversity.

  • questions, arguments: defined by the user, for example from situational questions (what, how, when, where)

  • possible solutions: defined by the user, for example from past experiences of innovation

It is used in Story to explain / argue the set and is based on the theory of Activity Systems and Patterns
