Backround

－ Geostat 1A,1B and 1C projects (2010-2014)– Creation of national population 1 km² grid data sets – Harmonisation of

• The grid net• Population data by 1 km² grids

– First attempts to describe the production process

－ Geostat 2 (2/2015) ->－ Premilinary ”Framework for Spatial Statistics”

• GSBPM – Generic Statistical Business Process Model (5.0)

GSBPM Generic Statistical Business Process Model

11 November 2015

－ The GSBPM describes and defines the set of business processes needed to produce official statistics.

－ It provides a standard framework and harmonised terminology to help statistical organisations to modernise their statistical production processes, as well as to share methods and components.

Processes of spatial statistics have also been described earlier …

－ Phases were identified independently – the GSBPM was not used

－ Interpretation of the process flow diagram is difficult – a certain level of abstraction would be needed

－ BPMN (Business Process Model Notification) was not used

－ The value of the work was to identify tools and instructions needed during the process

Objectives of Geostat 2 - and SF tasks

Geostat 2, Work Package 1:

Model for a point based administrative geospatial reference framework

Stat FI: － Aims to create a national model

– Define a role of spatial data in the statistical production process and using GSBPM describe a general process, alsodefine connections to other supportive systems (such as metadata, classifications, quality descriptions)

– Test the model: INSPIRE data product (demography)－ The model will be evaluated by others (AT, PT at first)

Rina Tammisto8

First questions and findings

－ What are the targeted processes?– Recognition of the key processes

• Relate to spatial statistics• Relate to map data

－ What is the ultimate outcome we aim at?– A preliminary model was illustrated

－ What should be the level of process descriptions in order to achieve a general model ?

Premilinary ”Framework for Spatial Statistics”

11 November 2015

- To introduce to the GSBPM- To identify key processes

- Inspired us to continue the work

- Good feedback !!

Modeling of processes – target processes

－ To start - perspective (traditional Geostat topic): Inspire, Demography - Population distribution

－ Identification of two processes:– Production of “Grid Net for statistics (1 km x 1 km)”– Production of “Spatial Statistics”– Production of statistical units (not yet, but most likely needed)

Modeling of processes Story Mapping method: http://www.slideshare.net/SteveRogalsky/user-story-mapping-in-practice

1. Writing down free cognitive associations (tasks) of the process

2. Classification of notes and identification of phases + completion by phases still missing

3. Identification of GSBPM phases + completion by phases still missing

4. Creation of the model + recognising actors

CREATING A PROCESS MODEL

MS Visio: BPMN Business Process Model Notification

Rina Tammisto13

Experiences－ The level of abstraction that is essential for understanding the

process must be chosen (as high as possible)– Helps identify similarities between processes

－ The process itself and the supportive sub-processes have to be distinguished

－ After finding the right GSBPM phases some missing phases could be detected

－ Some GSBPM phases must be repeated during the process Acceptable from the point of view of GSBPM instructions

e.g. In process phase 5 - 5.1-5.8• Actions in order to produce statistical data • Actions for combining statistical data with spatial boundary data

Experiences

－ Process phases are quite easy to fit to the GSBPM model!– The GSBPM model descriptions do not contain any

description or reference to spatial data - A GSBPM pro is therefore needed

－ Use of GSBPM requires raising the level of abstraction when interpreting phases – Suggestion: could the abstraction level be higher already

in phase descriptions of GSBPM?－ A big surprise: the method is very fast!

Lessons learned: GSBPM ”rules of use”

11 November 2015

1) Modelling itself is not the target – to understand the process is

2) Describe the process as it is – after selecting the level of

granularity

3) Apply the model – use it as a tool

Follow-up

Production process of spatial statistics in SF– A synthesis

A point based administrative geospatial reference Framework is the main goal－ The process model stands as a base

– Identify connections to other systems (such as metadata of data and processes, classifications etc.)

– Identify the actors (stakeholders involved)– Test the process for production with an INSPIRE compatible

data product (Demography)－ The model will be evaluated by others (AT, PT at first)
