  4. GridPP Survey • 56 responded. Results based on 44 complete responses. • Four themes: • GridPP • Improvisation • Distributed Management • Usability

  5. GridPP in General GridPP has been a successful project The funding regime for particle physics in the UK has a significant impact on the process and outcome of the UK particle physics Grid The development of the LCG has been strongly influenced by politics The UK particle physics Grid will work when LHC starts. Grids will contribute to the democratization of science. The IT industry would have done a better job if they were to undertake the development of the LCG

  6. The Most Positive Aspects Of GridPP

  7. Is the PMB sufficiently engaged with problems on the ground? • Attendance by PMB members at working meetings • Having an occasional joint dteam-PMB meeting is a good idea. • Improved information flow from experiment users to PMB; I sometimes wonder how much real user representation is at PMB level • More regular feedback from PMB on specific high-level issues (as they emerge) might be useful. Having the PMB minutes published is very useful. PMB does not need to be fully engaged with all problems on the ground.

  8. Do you consider the UK particle physics Grid as mainly … “I have never seen so much money wasted on providing solutions to problems that industry solved 20 years ago.” “Innovator, leading in many technical areas”

  9. Improvisation & Bricolage Careful planning is necessary to develop effective solutions I enjoy a high level of autonomy at work I wish I had more authority and control over people and resources I have a pretty good idea of what's going on in GridPP at a general level The limited control over issues like available resources, hardware, and technical solutions is a big challenge for GridPP Practical solutions are more important than rigorous methodologies

  10. How do you know what needs to be done in your job? Frequency: 1 - Never 2 - Rarely 3 - Occasionally 4 - Regularly 5 - Very often Comment: using meetings to update others

  11. If you have to suddenly leave your job and someone has to replace you, what essential skills should this person have? “Patience. The ability to remove your eye with a fork as it is less painful than being in some meetings.” “Large frustration threshold.”

  12. Distributed Management Value your experts. Motivate and keep them. It is hard to work in GridPP because it is so distributed? The collaboration works because there is a high level of trust in the community In GridPP, valuable knowledge is sometimes lost due to personnel turnover I don't pay much attention to who does what in GridPP apart from those I directly work with Developing duplicate solutions are a waste of resources Competition among parellel technical solutions is necessary in order to find the best one

  13. Frequency and effectiveness of communication methods Frequency: 1 - Never 2 - Rarely 3 – Occasionally 4 - Regularly 5 - Very often Effectiveness: 1 - Very ineffective 2 - Ineffective 3 - Average 4 – Effective 5 - Very effective

  14. How do you share your knowledge with other people at work? Mobilize “clusters of competence” Frequency: 1 - Never 2 - Rarely 3 - Occasionally 4 - Regularly 5 - Very often Effectiveness: 1 - Very ineffective 2 - Ineffective 3 - Average 4 - Effective 5 - Very effective

  15. Usability The UK particle physics Grid is easy to use The UK ticketing system is working well GridPP has worked closely with the users GridPP deployment and operations in the UK has done an excellent job in ensuring the usability of the Grid The EGEE middleware is easy to deploy and use The GGUS system has improved and is now working well The security of the UK particle physics Grid is sufficient The UK particle physics Grid is robust

  16. Communication methods with users Provide up-to-date contact details of technical experts. Frequency: 1 - Never 2 - Rarely 3 - Occasionally 4 - Regularly 5 - Very often Effectiveness: 1 - Very ineffective 2 - Ineffective 3 - Average 4 - Effective 5 - Very effective

  17. Theoretical perspective : organizational improvisation • Metaphors • Jazz (Weick 1992, 1999; Barrett 1998, Hatch 1999) • “discussions of improvisation in groups are built on images of call and response, give and take, transitions, exchange, complementing, negotiating a shared sense of the beat, offering harmonic possibilities to someone else, preserving continuity of mood, and cross-fertilization”. • Improvisational Theatre (Crossan, 1998) • Facilitative leadership, trust, influence and persuasion, fluid communication • Definition of Improvisation: “the conception of action as it unfolds, by an organisation and/or its members drawing on available material, cognitive, affective and social resources”. (Cunha 1999) • Convergence in time of conception and execution • Bricolage – finding solutions from available rather than optimal resources

  18. Analytical Framework : improvisation paradoxes

  19. Research Findings

  20. Contributions • Agile systems development can be scaled? • Embeddedness of agility • Large group performance is possible when the ambience is right. • Science vs art • Improvisation paradoxes • Scaled Agility should embody a deliberate or natural mixture of structure and improvisation, order and changes, intentionality and flexibility, spontaneity and reflexivity, collectivity and individuality • Practical implications: develop “organizational capability” to • Embrace uncertainties and risks • Enforce collaboration with strong motivation • Encourage innovation with supportive atmosphere (trust, autonomy, communication)
