Platform-based #digital transformation (example egov)

This blogpost is an example of digital transformation in e-government with the use of platforms (extracted from "e-government reference model #GeGF2014 #egov #entarch #bpm #soa" http://improving-bpm-systems.blogspot.ch/2014/10/e-government-reference-model-gegf2014.html  ).


In general, the e-government implementation architecture is as in Figure 1. It is a combination of an initial coordination platform (the social collaborative extranet) and an e-gov business execution platform (the coordination and integration backbone and functional services to be “cabled” to it).


Figure 1 Implementation architecture overview

Let us put this architecture in the evolution context. For the long time, e-government implementation architecture was portal-centric and its applications (blue "emabas") were extensions for some internal applications as show in Figure 2.

 

Figure 2 Implementation architecture – portal-centric stage

The proposed e-government implementation architecture is actually, the introductory architecture which introduces necessary flexibility. E-government applications may span several existing applications as shown in Figure 3.

        


Figure 3 Implementation architecture – introductory stage

As existing applications are evolving, they will be replaced by processes and services as well thus creating transitional application architecture as shown in Figure 4.


Figure 4 Implementation architecture – transitional stage

With converting all previously monolith applications into processes and services, the target application architecture will be reach as show in Figure 5. E-government applications will be just connections to a cloud of governmental services.

  


Figure 5 Implementation architecture – target stage

And, moving e-government to the really e-social system, the application architecture will morph into a social cloud interacting with the government service cloud as shown in Figure 6. The latter serves as a platform for social, professional, private, voluntary and other services to be integrated into e-social system.

  

Figure 6 Implementation architecture – e-social system stage

For existing e-government systems the evolution from the introductory architecture upwards does require primarily the systematic use of BPM and SOA. Green-field e-government initiatives may start from the target architecture.

All stages form a sort of ladder for step-by-step evolution as shown in Figure 7.

Typology of platforms

Platform concept

platform, noun
pre-existing piece of software to provide comprehensive functionality to other software pieces (i.e. applications) during some phases of their lifecycle


Note: Good platforms make simple things simple and complex things possible.
Note: "Piece" is a unit of deployment.
Note: All platforms are digital.
Note: Types of platforms mentioned below may be mixed in a particular software product.

Well-designed platforms follow the enterprise pattern Platform-Enabled Agile Solutions (PEAS) - see http://improving-bpm-systems.blogspot.ch/2011/04/enterprise-patterns-peas.html

See also "Achieving synergy between diversity and uniformity via platforms" http://improving-bpm-systems.blogspot.ch/2016/01/achieving-synergy-between-diversity-and.html and "Platform-based #digital transformation (example egov)" http://improving-bpm-systems.blogspot.ch/2016/01/platform-based-digital-transformation.html

Development platforms 

Origin: IDE
Typical characteristics: developed applications operate outside the platform
Typical provisioning: on-premises
Typical creator: FOSS or COTS

Technological platforms

Origin: runtime libraries
Typical characteristics: technology encapsulation for applications
Typical provisioning: on-premises
Typical creator: FOSS or COTS
Examples: ESB products, mobility, API gateways, etc.

Operational platforms

Origin: OS
Typical characteristics: platforms improve non-functional characteristics of applications
Typical provisioning: on-premises
Typical creator: FOSS or COTS or home-made
Examples: automation toolset for devops, monitoring, performance measurements, containers, virtualisation, application servers


Application platforms (programmable monoliths)

Origin: IDE
Typical characteristics: applications operates within such platforms only (beware of the vendor lock-in)
Typical provisioning: SaaS or PaaS, APaaS or on-premises
Typical creator: FOSS or COTS
Examples: BPM-suites, etc.

Functional platforms (configurable monoliths)

Origin: corporate functions automation
Typical characteristics: generic solutions have to be configured for needs of a particular business
Typical provisioning: SaaS or PaaS or on-premises or hybrid
Typical creator: FOSS or COTS
Examples: ERP, CRM, ECM
Note: Also called "Vendor platforms"


Intermediation platforms

Origin: portals
Typical characteristics: middleman between service consumers and service providers
Typical provisioning: IaaS or on-premises
Typical creator: home-made
Examples: Uber, Airbnb, Facebook, Alibaba, Paypal
Note: The owner of an intermediation platform helps to match demand and supply without any ownership over supplied resources (Uber does not owe cars, Airbnb does not owe hotels, Facebook does not generate any content, Alibaba does not produce consumer goods).
Note: Also called "Digital platform" or marketplace.

Business execution platforms

Origin: corporate functions automation
Typical characteristics: a coherent set of functionality sufficient to run business in a particular business domain as a set of solutions which are assembled from microservices.
Typical provisioning: hybrid or on-premises
Typical creator: FOSS or COTS
Examples: Salesforce
Note: Business execution platforms may be collected from previously mentioned platforms.

Corporate Unified Business Execution (CUBE) platforms

Origin: digital transformation, application portfolio rationalisation, application portfolio modernisation,  legacy ERP transformation, etc.
Typical characteristics: whole-enterprise-specific business execution platform
Typical provisioning: hybrid
Typical creator: home-made
Example: http://improving-bpm-systems.blogspot.ch/2015/10/enterprise-patterns-peas-example-cube.html
Note: Corporate unified business execution platforms are collected from previously mentioned platforms.
Note: Also called "Digital business platforms".


Potential industry-sector synergy


Any corporate within the same industry-sector do, in principal, the same things but in slightly different way. If a corporate unified business execution platform enables synergy between diversity and uniformity then the same platform may serve the whole industry-sector (public services, healthcare, smart-city, etc.).

#egov to help #UNDP about better governance and anti-corruption

This post is inspired by the article "The time is right to place governance and anti-corruption at center stage" (http://www.undp.org/content/undp/en/home/ourperspective/ourperspectivearticles/2013/09/30/the-time-is-right-to-place-governance-and-anti-corruption-at-center-stage-rebeca-grynspan.html#!). The article ends with "Talk to us: How can we help governments establish credible mechanisms to fight corruption?". My answer to this question is below.

As an architect of complex information systems (at the scale of canton, confederation, country, and continent), I think that a systemic approach to reduce the corruption is based on a proper architecture for e-governments and e-governance. Such an architecture will make everything transparent and traceable (thus accountable and trustful) by:
  • open design of e-government and e-governance as a system (to guarantee that various components are working together)
  • execution of e-government and e-governance services as explicit processes (to know who did what)
  • third-party reviews of anonymized data, documents and processes (to catch problems proactively) 
  • external archiving of governmental audit trails (to implement perfect records management) 
  • making public some governmental data (to generate open data)
  • systematic evolution of e-government and e-governance (to continuously improve the services)
My experience shows that many e-government and e-governance applications are almost the same in various ministries and countries. The level of variations between countries is estimated at about 20 %. Thus it is possible (thanks to modern information technologies) to develop a common platform for e-governments and e-governance which is implemented once and then employed many times in, for example, developing countries.

In more details this concept is presented in my several public blog posts:

#e-government and #e-governance reference model #entarch #bizarch #apparch

This blogpost about e-gov reference model is a continuation of the blogpost "How many #entarch projects do you need in your #e-government & #e-governance initiative?" (see http://improving-bpm-systems.blogspot.ch/2013/09/how-many-entarch-projects-do-you-need.html).

Four possible types of interactions between the government and citizens, local businesses and other organisations (briefly, partners) as shown in figure below.

These types of interactions are:
  1. The government sends an announcement, e.g. that a law has been changed.
  2. A partner sends a declaration (also some kind of announcement) to the government, e.g. that this citizen has changed his/her address.
  3. The government demands a partner to do something, e.g. to pay taxes.
  4. A partner demands the government to do something, e.g. to provide a fishing certificate.
The last two types of interactions can be long-running interactions - there may be some noticeable time (weeks) between sending a demand (start) and receiving the result (finish). Even, the partner and the government may interact between the start and finish as shown in figure below.


In addition, the partner may have to deal with various ministries within the government. Usually, each ministry works in own way thus complicating life of the partner as show in figure below.

To protect the partner from the internals of the government and to unify his/her interactions with the government, the e-government acts as a shell which coordinates the flow of data (and documents) between the partner and the government. The e-government treats all government work as a processes. These processes fulfil their goals by coordinating various services.  For example, a partner's demand can be a result of joint work of three ministries in four steps as shown in figure below. The blue circled numbers show the process (flow of control) steps.

The related flow of data (and documents) is shown by the red circled labels in figure below.

Each step on two previous figures is actually a process fragment which may be rather complex. For example, the details step #2 show (see figure below) that one of its activities is a task for the partner (activitiy 2b).

A possible sequence of the execution of this fragment is shown in figure below by the red circled numbers.

The usage of processes simplifies:

  • notifying the partner about the progress in processes related to him or her
  • monitoring of SLA
  • continual improvement


To streamline the work of partners with the government, e-government provides a social collaborative extranet for all partners. This extranet :
  • helps partner to manage all electronic documents (which are exchanged between the partner and the government) in a secure manner,
  • helps partner to execute his/her tasks,
  • allows a partner to interact with other partners.
This extranet is an interface layer between the partners and e-government (thus with the whole government as well) as shown in figure below.

The partner's view

For the partner, this extranet may have the following visual design.

This extranet considers that:
  • Each partner has several roles, e.g. YOURSELF (person and his/her legal representatives), CITIZEN (person officially leaving in this country), ENTERPRISE (manager of a business), SENIOR (persons with age over 60), etc.
  • Person may select which roles he/she is carrying out at a particular moment in time.
  • Each communication between a partner and the government is a case with associated documents, data, audit trails, records and KPIs.
  • A case may be completed or on-going.

The inter-ministerial integration view

E-government, which is acting also an inter-ministerial coordination tool, ultimately resolved the integration problem. Instead of that ministries are connected to each other in ad-hoc way, the e-government offers an integration process which delivers data and documents between all ministries in a systematic way as shown in figure below. It is actually a centralised service for the inter-ministries secure electronic exchange (like sending / receiving registered letters).
Generally, the backbone is decoupled from intra-ministry applications through two adapters: dispatcher (handle messages coming from the backbone) and expediter (handle messages going to the backbone). To be transmitted through the backbone, each message (business data and documents) is protected by three "envelopes" (marked by blue circled number in figure below):
  1. Business (processing) envelope
  2. Delivery (addressing) envelope
  3. Transportation (routing) envelope


Of course, the access to open reference data (e.g. list of addresses in the country, some geodata, etc.) is different.

Application architecture (platform-based)

In general, the e-gov application architecture is as in figure below. There are three main technologies:
  1. Enterprise Content Management (ECM) for the social collaborative extranet
  2. Business Process Management (BPM) for coordination and integration backbone
  3. Service Oriented Architecture (SOA) for coordination and integration backbone

Let us put this application architecture in the context. For the long time, e-gov application architecture was portal-centric and its applications (blue "emabas") were extensions for some internal applications as show in figure below.

The proposed architecture is actually, the introductory architecture which introduces necessary flexibility.  E-gov applications may span several existing applications as shown in figure below.
 

As existing applications are evolving, they will be replaced by processes and services as well thus creating transitional application architecture as shown in figure below.

With converting all previously monolith applications into processes and services, the target application architecture will be reach as show in figures below. E-gov applications will be just connections to a cloud of services.
 

And, moving e-gov to the really e-social system, the application architecture will morph into a social cloud interacting with the service cloud as shown in figure below. The latter serves as a platform for social, professional, private, voluntary and other services to be integrated into e-social system.

 

Important that for existing e-gov systems the evolution from the introductory architecture upwards does require only the systematic use of BPM and SOA. Green-field e-gov initiatives may start from the target architecture.

How many #entarch projects do you need in your #e-government & #e-governance initiative?

Imagine, that a country wants to implement its e-government and e-governance correctly. One of the critical measures of implementation "correctness" is minimal (ideally, total avoided) duplications in its e-government and e-governance implementations while following the goals and priorities of the country. The ideal situation should be achievable when e-government+e-governance is created practically from the scratch as, for example, in many developing countries.

Typical country has the following levels of government:
  1. National (or federal) 
  2. Federal ministries and agencies
  3. Regional (or cantonal or provincial) authorities with their ministries and agencies
  4. Districts (and sometimes sub-districts) authorities
  5. Communal authorities
Depending on the country political system, the separation of power between national, regional and communal levels are different. In "parliamentary republic", more power is at regional level. In "constitutional monarchy", the power is at national level. But, from the government-as-a-system point of view, there are several communicating governmental entities which are working together as one whole to provide services to citizens, business and other non-governmental/social organisations.

We know that e-government+e-governance is a complex system:
  • Unlimited life-cycle (unpredictable and incremental evolution) 
  • Socio-technical system (how you do something is sometimes more important than what you do)
  • Collaborative system 
  • Industrialised system 
  • Ability for rapid innovation is important 
  • Variety of services (several hundred governmental services are listed in the Swiss e-government catalogue http://www.ech.ch/vechweb/page?p=dossier&documentNumber=eCH-0070&documentVersion=4.00)
  • High level of security for personal data
A system of such complexity must be properly architectured with all power of  #entarch and other technologies.


So how many #entarch projects should be carried out?

One estimation (found in an procurement notice from a UN agency) is "Each entity within the Country will be required to define their enterprise architecture for provisioning of e-Governance Services and improving the efficiency and effectiveness of the public sector." In this Country there are 40 ministers, 18 provinces, about 100 districts (with a few sub-districts each) and unknown number of communes.

Hope that the Country is not going to have 200+ #entarch projects although this will be a diamond mine for consultants. For example, I saw a one-year long with the budget of 500 000+ EUR project just for building an initial enterprise architecture. After 4 years only a fraction of its recommendations were implemented and changes in the business required continuous modification of the architecture as it was not flexible enough.

Keeping in mind the guidance of the minimization of duplications, let us analyse each level.

Communal (and district) level

By definition, all communes and districts provide the same services. Thus the technical, data, application and business architectures should be the same. Although those governmental entities may have different capabilities, the enterprise pattern ADO (see http://improving-bpm-systems.blogspot.ch/2013/09/enterprise-patterns-anisotropically.html) provides guidance how to handle this situation.

Provincial level

All provinces provide the same services, but with some internal variations as their structures, priorities, even laws may be different. Nevertheless, the technical, data, and application architectures should be the same. At the business level, different provinces carry out the same e-government and e-governance services via slightly different processes which use the same services. The blogpost  (see http://improving-bpm-systems.blogspot.ch/2013/02/enterprise-patterns-peas-example-and.html)  shows how to achieve a common set of services and assemble them into your slightly different processes.

Important, that the modelling of business processes must be standardised so different analysts find similar services in similar capabilities. A modelling procedure which can considered is available at  http://improving-bpm-systems.blogspot.ch/2013/07/bpm-for-business-analysist-modelling.html .

Ministerial level

As different ministries have different core businesses, their architectures will be different in some extent.
  • Technical architecture can be almost the same (except if some unique functionality is required).
  • Data architecture of each core business actually must be shared among the whole e-government and e-governance thus to be aligned at the national (i.e. centralired) level.
  • Application architecture of each ministry consists of 20-40 % of unique applications and the rest are common (within the whole e-government) applications. If possible, all applications (the both unique and common) are architectured in a similar way, e.g. http://improving-bpm-systems.blogspot.ch/2011/07/enterprise-patterns-caps.html
  • Business architecture may look very different unless processes patterns are systematically used. Various process patters are available at http://improving-bpm-systems.blogspot.ch/search/label/practical%20process%20patterns . Being armed with those patterns in, organisations will be concentrating on the unique business challenges and not wasting time for re-inventing the wheels. 

National level

This level is, practically, a decision-making mechanism which works together with the ministerial level. The vaste majority of work is to prepare, validate and approve documents in accordance with several decision-taking patterns (AS to write a blogpost "decision-as-a-process").

What is common?

Technical and data architectures are practically common. Application architecture is shared at about 80-90 %. Business architecture is shared at about 70 %.


Technical architecture
Data architecture

Business acrhitecture
Number of unique #entarch projects

It seem that instead of #entarch project for each governmental entity, it is necessary to consider the the e-government and e-governance as a system and to concentrate on the common components. So, one #entarch project and several solution-architecture projects (to develop common components) should be enough.

Some of common components are mentioned below.

Reference model for e-government and e-governance (more details are in http://improving-bpm-systems.blogspot.ch/2013/10/entarch-e-government-and-e-governance.html)


In accordance with this architecture, the partners of a government (citizens, businesses, organisation, and other governments) will communicate with the government through a social collaborative network. The latter is based on modern Enterprise Content Management (ECM) tools and provides various functions for various partners. For example, each citizen can announce to the government changes in his/her situation (e.g. change of address) or can request from the government some documents (e.g. certificates). The social collaborative network allow implementation not only of citizen-to-government services, but also of communities-to-government services thus enabling e-governance.

Any work within the government is a process. The processes fulfil their goals by coordinating various services. The latter are provided by the government, and private and other partners. The use of processes allows higher transparency (who is doing what, how, why and with what results), better visibility (following up of citizen’s requests), more flexibility (assembly of processes from services), faster implementation (assembly from existing and new services) and easier integration between various governmental agencies (via secure processes).

Common data dictionary and virtual MDM

All data element must be centrally managed (firstly, standardized).  In Switzerland, it is done at the federal level - http://www.ech.ch.

Common agile application architecture

This architecture should be based on BPM and SOA. From the business point of view on BPM and SOA, an executable process coordinates some services as shown in figure below.

But from the IT point of view, there may be many different services around each process, because a process requires various artefacts: events, roles, rules, documents, data, audit trails, and performance indicators. To help structure different services and other artefacts around processes, a multi-layer implementation model (see figure below) is proposed for BPM/SOA solutions. In this model, each layer is a level of abstraction of the business and addresses some particular concerns.

Common implementation platform

As it is mandatory to avoid the duplication of work among different organisations and among various projects within each organisation, the use of the platform pattern is of critical importance (see enterprise pattern PEAS at http://improving-bpm-systems.blogspot.com/search/label/PEAS ).

Ideally, all common capabilities should constitute a national implementation platform, which is available for all organisations. Instead of re-implementing the same common capabilities, different organisations will implement only their specific services on top of this platform (see figure below). E-province can be the first step in the realisation of the national implementation platform. This enterprise pattern combines the advantages of the platform with opportunities for quick delivery:
  • to standardise and simplify core functionality as a coherent foundation and 
  • to speed up the implementation of new innovative solutions on top of the foundation.



The platform is a coherent set of governance rules, architectural principals, best practices, integration patterns, shared ICT tools and solutions. Key characteristics of the platform are:
  • incremental creation and gradual deployment; 
  • high maturity level of corporate basics, e.g. with records management, risk management, electronic management of documents, and management by processes; 
  • high maturity of IT operations, management and governance; 
  • everything is transparent and traceable (thus trustworthy): 
    • design of e-government as a system, 
    • execution of e-government and e-governance services, 
    • management of data and document repositories,
    • some data are open,
    • evolution of e-government and e-governance
  • risk-awareness (including proactive risk evaluation) is built-in by design; 
  • paperless exchanges between government, citizens, business, and other partners from the civil society; 
  • opportunities for public-private partnership. 
Typical generic capabilities of the platform are:
  • Identification
  • Authorisation
  • ESB
  • BPM
  • Document management
  • Record management
  • Decision management
  • Complex Events Processing
  • Data warehouse, reports, analytics
  • Traceability
  • Security by process
  • Digital and mobile work
As the platform becomes mature and gradually enriched, the agile implementation of e-government and e-governance services will be enabled. The benefits gained from the platform will depend on the readiness of each organisation: each is permitted to progress at a suitable pace. A “ladder” or “maturity model” (see figure below) is a metaphor for suggesting how a set of organisations with different abilities might achieve common goals and plan their progress. The “ladder” has a few levels of capability from “not able” to “fully capable”.

Common inter-governmental-entities communication (data and document exchange) backbone

From everyone to everyone connectivity, the governmental agencies should use a single and secure "postal" backbone service. (see an example from Switzerland - http://www.bfs.admin.ch/bfs/portal/fr/index/news/00/00/02.html)

Example of common components working together

Slides with * contain animations - better to download this presentation.


Idealistic plan for implementation of e-government and e-governance

  1. Establish a strong #entarch function 
  2. Agree on the governance for common components 
  3. Start to implement them and unique components in accordance with the national strategy (see http://improving-bpm-systems.blogspot.ch/2013/04/enterprise-patterns-strategy-to.html)

Conclusion

Conceptual integrity is mandatory to reach some coherence in decisions about:
  • Optimisations for users (external and internal)
  • Compliance with laws
  • Avoiding duplication of work among ministers, provinces, municipalities
  • Simplification of evolution of applications
  • Realisation of the strategy
  • Natural evolution of e-gov
  • Standardization of business processes fragments and unification of software
  • Introduction of new tools and technologies
For a green-field e-gov one 1 #entarch project is necessary (in which we have to establish the conceptual integrity).

An example of conceptual integrity is http://improving-bpm-systems.blogspot.ch/2013/04/enterprise-patterns-strategy.html

Enterprise patterns: Anisotropically Decentralized Organisation (ADO)

Business situation: Branch Offices (BOs) with different level of skills and staffing have to carry out similar processes; the Central Office has to support them. (A possible BOs - CO scenario is local governments - federal government.)

Consider that any activity can be decomposed in four logical steps (similar to PDCA cycle):
  1. Plan: preparation for the work to be done;
  2. Do: execution of the work; 
  3. Validate: checking of how good and correct the work has been done; 
  4. Reflect (also can be called re-factor): analysis of the newly obtained experience and results to propose/implement some improvements to similar work which will be done in future.


Under decentralisation, each step can be carried out in a few different combinations of the participation local (L, i.e. at a particular branch office) and central (C, i.e. at the headquarters) resources. For example, if a particular branch office has no experience with the procurement of a particular type of service then such procurement should be carried out at the HQ. It is considered that central resources are capable doing any activity (which implies also any step within any activity).

Possible combinations are:
  • [C] fully centrally (i.e. no delegation) 
  • [L] fully locally (i.e. complete delegation) 
  • [LC] with central post-control 
  • [CL] with central pre-advice 
  • [CLC] with central pre- advice and post-control 
Only some of those combinations are really applicable in each of those four steps.
  • Plan – C, L, LC, CL, CLC (some consultations between local and central resources are possible and sometimes are mandatory) 
  • Do – C, L (actual work can be done only by one resource) 
  • Check – C, L, LC 
  • Reflect – C, L, LC 
Those combinations are not independent and they are combined in a few variants which are actually some kind of degrees of decentralisation of a particular activity.

Those variants also may be considered as branch office capability maturity levels:
  • 0 none 
  • 1 technical 
  • 2 managerial 
  • 3 defined 
  • 4 managed 
  • 5 optimising 

The trick is how to choose the best variant which should be used for a particular activity in a particular process instance within a particular branch office to be done with particular people (implied branch office staff). It can be done some kind of an “decision” system which
  • “knows” processes, activities and local specifics;
  • traces the actual capabilities and expected performance of people and processes; 
  • estimates different risk factors (political, financial, etc.) and degree of compliances; 
  • helps to choose the best (in particular circumstances) variant and - justifies any other actions. 

Such a decision system should be systematically consulted “between” normal activities. In some sense, it is responsible for overall controlling, measuring of outcomes, overall planning and overall guidance during the cause of execution of project’s normal activities. It should be carried out by central resources because it should have access to the enterprise-wide knowledge. Such a decision mechanism may work together with DAM pattern - http://improving-bpm-systems.blogspot.ch/2012/07/practical-process-pattern-dam.html
