I Concurrent Instructional Engineering

• As engineer of telecommunication, computer,
  information and instructional systems, I have
  observed the strong correlation between the
  management of processes producing knowledge and
  objects.
• the concurrent engineering of any system
  involves a level of knowledge and learning
  management
• the development of instructional systems
  involves concurrent engineering methods
• The profound cause is the circular tie between
  acting and knowing to do you must know, to know-
  you must learn, to learn you must do etc.
•  I have explored the relationship between
  semantic and instrumental engineering, in a
  series of projects (note 1) searching answers for
  questions like
• "With what strategies and tools X should we equip
  technologists A and methodologists B, which wish
  to supply with composition and management methods
  and instruments Y a public of authors C and
  managers D, which organize instructional systems
  Z, in which a group of assistants E can instruct
  a group of learners F so that they obtain an
  amelioration G of their competences in the
  knowledge domain H, necessary to accomplish the
  performances I in the contexts J- the global
  solution being optimal, according to criteria K,
  verifiable by the methods L".

a Combining persons and objects in managing
knowledge

• Socio-technical systems involve objects
  (instruments, documents) and human participants
  processes involving cooperating persons whose
  competences (made or not explicit) evolve in
  contact with support resources- ask for a
  concurrent semantic engineering
• Besides input-output functions, the systems
  behavior depends on their state humans embody
  evolving knowledge- their internal transformation
  beinglearning
• The modification of knowledge is produced by
  experience or by explicative collaboration
  (communication, co-action) the explanation is
  based on the cognitive consonance in assistant-
  assisted pairs documents explain asynchronously,
  representing their author
• Besides the identification of a concept by its
  name (using implicitly the natural reference
  system of the language), we may employ semantic
  coordinates respective to knowledge domains, used
  as reference systems
• The characterization of the rapport vis a vis
  of an identified concept K (mastery level,
  qualitative abilities, explicative capacities)
  defines competencesC their evolution
  (learning) may be the goal or the means of an
  activity
• The explicitation of competence evolution may
  orientate the choice of support persons and
  documents the optimization of resource
  allocation is facilitated by the indexation of
  participants, documents and activities- on a
  unique knowledge reference system

5
b Combining sequencing and parallelism in
orchestrating concurrence

• The management of concurrent activities requires
  tools for modeling and orchestrating sequencing
  and cooperation- in ensembles composed by people
  and instruments
• When cooperation has an explicative goal
  (support, instruction), tools like CSCW, DSS, WFM
  must be enriched for CSCE (computer supported
  cooperative explanation)
• with a layer for the management of the involved
  knowledge and of the facilities (services) based
  on it (advising, resource matching, etc)
• with facilities for sharing operations to explain
  (double command controls, replicated
  architectures)
• The modeling and management of long evolutions-
  like the lifecycle of a system- or that of
  interlaced processes that compose a complex
  physiology- resort to meta-procedural
  aggregation, cascading procedural chains.
• The process chaining (concurrence) relies on
  sharing components (and sense), an object
  produced in a process (or an instructed
  participant) being usable as instrument/raw
  material (respectively guide) in another apart
  the procedure linking as phases of a procedural
  chain (like in the recursive aggregation of
  composed resources) we also encounter links
  between a procedure and the guiding (support)
  meta-procedure
• The passage from the modeling of a workflow
  (flowchart) for a group of concurrent procedures
  to their orchestration on the base of the model
  (model enactment) is a meta-process that requires
  meta-management tools.

c Combining structures and processes in a 4d
systemic vision

• The CE should approach the concurrence phenomena
  with a 4d ontological vision (Note) observing
  systems in process lifecycles and fluxes
• Instead of interlacing the design-development
  cycles of successive versions- typical for
  reengineering- a longitudinal engineering vision
  (global in time) pursues the continuous
  transformation of the system (its life-evolution)
• Procedural models form an evolving whole with the
  reality that they represent or influence The
  model-reality loop can be treated with
  meta-models, that allow the management of models
  life mode
• The diffusion (propagation, phylogenesis) of
  knowledge in a community- can be seen as a
  cascade of explicative processes, but also as a
  reproductive act of the collective brains
  physiology
• The reproduction of objects is realized through
  production cascades (fluxes) a grand-mother
  system is used for the construction of mother
  systems that allow the conception of child
  systems. The (phylo)genetic vision asks the
  pursue of the circulation (and transformation) of
  material and cognitive entities along the
  productive chains.
• We can manage the procedure reproduction with
  metafunctions

d Combining planning and emergence in adaptable
scenarios

• concurrent engineering oscillates between careful
  planning and emergent decisions.
• the careful conceptual planning (with the early
  involvement of the aimed users) seek in CE was
  also considered in the TELOS vision document the
  conceptual architecture is seen not only as a
  pre-condition of the product but as a part of it,
  the intellectual capital, less sensitive to
  technological modification it have to be,
  however, continuously modified, reflecting the
  evolution of the target products physiology
• evolving along with the system it reflects and
  pilot, the LORNET use cases become instruments
  for management, assistance, demonstration and
  test
• the tension between the process emergence (for
  maximal adaptability) and planning (for maximal
  coherence) leads to mixed strategies such as
  influencing by preparing support aggregates,
  observing and modeling emergent phenomena and
  reproducing them, using the models
• the management based on functions stresses on
  the adaptation of scenarios, through progressive
  concretization of abstract resources the choice
  of concrete resources uses semantic matching
  services, based on the competence equilibrium
  around operations with various topologies
  (executor, assistant, instrument etc)

e Combining analytic and pragmatic approaches in
treating complexity

• The CE analytical orientation to global planning
  confronts complexity. It can determine
  calculability bottlenecks (increase the costs of
  optimization efforts to a prohibitive level).
• Example. The competence management may encounter
  problems like privacy rules, authority and
  responsibility for evaluations. The cumbersome
  declaring and updating efforts can bring to the
  abandon of competence tracking or to the choice
  of a thick descriptive granulation
• In such cases we resort to simplifications,
  according to a "pragmatic" orientation get the
  most useful services through the most accessible
  means seeking the optimization of the
  effort/result ratio.
• Example. A practical solution is the facilitation
  of the orchestration between the actors
  determining the evolution of the target system.
  The functions offer services for information
  (inspiration,guiding) declaration (traces,
  annotations, memorization, piloting advise)
  resource manipulation partner coordination
  matching

f Combining technical, semantic and
administrative criteriafor facilitating
interoperability

• In the emergent mode , users search resources
  semantically pertinent, technically usable, and
  administratively accessible
• In the orchestrated mode, designers do the same
  operations , finding resources to connect
  aggregate in prepared applications
• When the services and resources sources are
  distributed in different systems, concurrence
  poses interoperability problems
• In a space open to semantic and technical
  inter-operation, drawing frontiers for systems
  and segmenting processes can have administrative
  justifications (rights, responsibilities).
• LORNET production cascades (recursive aggregation
  chains) are segmented on administrative criteria

Manage concurrent research

• Coordinating the 6 LORNET teams poses concurrent
  research problems
• What could have happened the recourse to the
  method (projects aiming at the construction of
  tools for the management of projects manageable
  with the conceived tools) epistemological
  complications and opportunities for a spiral
  refinement- created by this circular situation
• What is happening some contexts do not favor
  convergence
• Projects that involve a team of experts from
  various disciplines require a communication
  language and an orchestration methodology
  metaontologies for research contexts as semantic
  and pragmatic web applications
• An integrative approach would be necessary, one
  that would remake the unity of the observation's
  target, coagulating a model image. In my PhD
  thesis, I have tried to conceive a model for the
  (instrumented) explanation phenomena, one that
  would integrate the multitude of involved
  aspects, coagulating the observations extracted
  from a multitude of domains (psychology and
  cognitive sciences, communication and information
  sciences, semiotics and multimedia, logics and
  epistemology, sciences of education, computer
  telecommunications, theory of negotiation and
  decision, etc)- each having its own primitives,
  epistemology, language, paradigms, experience,
  rituals, models and priorities.
• my presence to the conference is a challenge
  towards this convergence
