10 « ex bonnes pratiques » à abandonner et... 10 bonnes résolutions pour 2014 - Première partie

 

2014En ce début d’année 2014, je vous souhaite à tous les lecteurs de ce blog une excellente année, pleine d’innovations dans la construction de votre Système d’Information  en s’appuyant sur la R2I, Révolution Industrielle Informatique.

Best-PracticesDans ce premier texte publié en 2014, je vous propose d’identifier 10 « ex bonnes pratiques » qui sont devenues, aujourd’hui des « mauvaises pratiques ».

Votre première, et difficile résolution, sera de prendre la décision d’abandonner définitivement ces mauvaises pratiques.

Il faudra ensuite identifier les « nouvelles bonnes pratiques » à mettre en œuvre à partir de 2014. Ce sera fait dans la suite de cette série.

Important : il ne s’agit pas de porter un jugement de valeur sur ces « ex bonnes pratiques ». Elles avaient leur raison d’être, hier ; aujourd’hui, dans un monde informatique qui a profondément changé, elles deviennent des freins très dangereux qui bloquent l’innovation et la performance des Systèmes d’Information.

J’ai classé ces « ex bonnes pratiques » en quatre familles :

  • Postes de travail : 1, 2 et 3
  • Serveurs : 4
  • Applications, usages : 5, 6, 7 et 8
  • Management : 9 et 10

  

1 - Postes de travail obèses, PC 100 % wintel

Huge PCDepuis le début des années 1990, les postes de travail PC Wintel (Windows Intel) ont dominé l’informatique des entreprises. Pour un trop grand nombre de responsables informatiques, la réponse à toute demande est : une application qui fonctionne sur un PC Wintel, avec un écran de 15 pouces ou plus.

Nous sommes maintenant rentrés dans l’ère Post PC. Ceci ne signifie pas que les PC Wintel vont disparaître ; ils vont simplement devenir une plateforme parmi beaucoup d’autres, smartphones, tablettes, chromebook...

 

2 - Master PC

Masteriser PCLa gestion de ces PC Wintel est vite devenue un enfer pour les responsables informatiques. Leur réponse a été de créer un « Master », une version unique du PC pour tous les collaborateurs de l’entreprise, quels que soient leurs métiers ou leurs besoins.

Les entreprises ont compris que l’efficacité de ce Master PC n’était qu’une illusion, une coûteuse illusion. 

  

3 - Suites bureautiques obèses

Suites bureautiquesEntre les années 1990 et 2000, Microsoft a gagné deux batailles majeures, qui ont été à l’origine de sa spectaculaire réussite  :

  • Celle du poste de travail Wintel, évoquée ci-dessus.
  • Celle des suites bureautiques avec Office et ses formats propriétaires, ne laissant que des miettes aux concurrents. 

Malgré leur gratuité, les solutions Open Source n’ont jamais pu s’imposer et ne le feront jamais. Après 20 ans de bons et loyaux services, il est temps de mettre ces suites bureautiques dans des maisons de retraite, pour leur permettre de finir leur vie dignement.

En résumé : suite bureautique = machine à écrire du XXIe siècle.

  

4 - Clouds privés

Private cloud Microsoft HPCloud Privé ? Il s’agit là d’un cas particulier : une « ex bonne pratique » qui commence à peine à se mettre en place et qu’il est urgent de tuer avant qu’elle ne fasse des dégâts monstrueux.

Je suis assez confiant sur ce sujet et je pense que l’expression « Cloud privé » aura disparu de notre vocabulaire dans les 2 à 3 ans qui viennent.

  

5 - Solutions intégrées

Integrated solutionsIntégré, Intégration, intégrateur... tous ces mots sont omniprésents dans le vocabulaire des informaticiens. 

Encore une illusion qui disparait : celle qu’un fournisseur, une solution puissent répondre à tous les besoins d’une entreprise. C’est une réalité pour les TPE, les métiers très standardisés tels que les notaires ou les dentistes, mais cela n’a aucun sens pour les entreprises. Plus elles sont grandes, plus cette illusion est dangereuse et c’est pourtant les très grandes organisations qui ont cherché pendant très longtemps ce Saint Graal de l’intégré.

Intégré : un autre mot à rayer de votre vocabulaire en 2014.

  

6 - Unicité des solutions

Taille unique
Cette quête de l’unicité a été universelle dans l’informatique pendant ces 20 dernières années. On l’a déjà évoqué pour les postes de travail Master, les suites bureautiques... 

Cette lubie de l’unicité touche aussi les logiciels : le même programme de paie pour tous les pays, le même logiciel de décisionnel pour tous les utilisateurs, une seule solution de gestion de projets, qu’ils concernent 5 personnes ou 500...

Nous vivons dans un monde extraordinairement varié, et c’est ce qui en fait la richesse et la valeur. L’informatique restera-t-elle le dernier bastion de ce mythe de l’unicité ?

Je compte sur vous pour que cela ne soit plus le cas...

  

7 - Le tout ERP

ERPPopularisés dans les années 90, les ERP, et en particulier les deux leaders SAP et Oracle Applications, sont omniprésents dans la majorité des grandes organisations.

Et une illusion de plus qui fait « Pschitt » ! Comment l’idée saugrenue qu’un logiciel puisse répondre aux besoins de milliers d’entreprises, quel que soit leur secteur d’activité, pour toutes les fonctions, financières, RH, commerciales... a pu être « gobée » par des décideurs raisonnables, restera toujours pour moi un grand mystère.

En 2014, il faudra manier le bistouri informatique avec dextérité pour, composant par composant, élaguer les ERP installés d’un maximum de fonctionnalités qui peuvent être confiées à des solutions SaaS industrielles.

 

8 - Applications Client / Serveur

Server_clientAvec l’arrivée du PC Wintel roi, les entreprises ont déployé des logiciels dont une partie des fonctionnalités étaient déportées sur ces PC, l’autre partie restant sur des serveurs. 

L’impossibilité de gérer proprement des centaines d’applications C/S sur des milliers de PC est devenue tellement évidente qu’une majorité d’entreprises ont été obligées de réinventer le « client léger » en remplaçant ces applications Client / Serveur par des applications Serveur / Serveur, pour le plus grand bénéfice d’éditeurs comme Citrix.

La solution ? Comme mesure conservatoire, ne plus déployer en 2014 une seule nouvelle application Client / Serveur.

 

9 - Maîtrise d’Ouvrage, Maîtrise d’Œuvre (MOA / MOE)

MOA MOE BrouetteMaîtrise d'Ouvrage, Maîtrise d'Œuvre : cette invention française n’a heureusement pas franchi les frontières de l’Hexagone, mais ses dégâts en France ont dépassé ceux des plus grandes tempêtes de ces dix dernières années.

La décision à prendre pour 2014 est simple : plus aucun nouveau projet informatique ne sera piloté par la démarche MOA / MOE. 

  

10 - Schémas directeurs 

Schéma directeur informatiqueC’est une autre spécialité française, avec un « pôle d’excellence » dans le secteur public : élaborer le « schéma directeur » de son Système d’Information, avec un horizon de planification qui approche souvent les 5 années.

Dans un monde imprévisible, où les entreprises, les technologies, les attentes des utilisateurs internes et externes changent de plus en plus vite, cette vision « cartésienne idéale » de ce que devrait être un Système d’Information dans plusieurs années est une utopie dangereuse.

En 2014, tous les budgets qui avaient été alloués à des schémas directeurs sont annulés ; on trouvera beaucoup de projets innovants qui pourront profiter de ces ressources libérées.

 

Situation actuelle dans les entreprises

La majorité des entreprises ont, bien entendu, et depuis longtemps, abandonné ces « ex-bonnes pratiques » !

 10Pour celles qui ne l’auraient pas encore fait, il est possible de réaliser un diagnostic rapide sur le niveau d’obsolescence de votre Système d’Information, en comptant un point pour toute « ex bonne pratique » qui est encore en vigueur dans votre entreprise.

  • 3 points ou moins : bravo ! Vous êtes sur la bonne voie, continuez.
  • Entre 4 et 6 points : vous avez fait une partie du chemin. Vous pourrez rejoindre, en 2014, le peloton de tête des entreprises performantes en continuant vos efforts.
  • 7 points et plus : alerte ! Vous avez devoir mettre les bouchées doubles en 2014 pour essayer de remettre à niveau votre Système d’Information.

Last week, while in San Francisco, I used the Uber app and service four times. All four experiences were great, although one of the drivers stopped for 30 seconds and then left as I was walking up to the car. He must have realized I was a blogger. None the less, the next car was just a minute away and I suffered no pain. In this article, my colleague, Ved Sen, Global Head, Advisory Services Social, Mobile and Sensors at Cognizant shares his experiences and insights.
We are reaching the end of the beginning with WebRTC and real systems using this technology have begun to appear. One challenge that faces every WebRTC deployment (in some form or another) is identity management. For example, if you have an existing service – possibly built on a variety of different PaaS/SaaS offerings – and you want to add real-time communications you are faced with a challenge relating to user management, authentication, authorization, and validation. Service providers will want to use their existing identities, but these will have credentials already that are (hopefully) irreversibly encoded. In his session at Internet of @ThingsExpo, Peter Dunkley, Technical Director at Acision, will look at how this identity problem can be solved and discuss ways to use existing web identities for real-time communication.
Can call centers hang up the phones for good? Intuitive Solutions did. WebRTC enabled this contact center provider to eliminate antiquated telephony and desktop phone infrastructure with a pure web-based solution, allowing them to expand beyond brick-and-mortar confines to a home-based agent model. It also ensured scalability and better service for customers, including MUY! Companies, one of the country's largest franchise restaurant companies with 232 Pizza Hut locations. This is one example of WebRTC adoption today, but the potential is limitless when powered by IoT. Attendees will learn real-world benefits of WebRTC and explore future possibilities, as WebRTC and IoT intersect to improve customer service.
From telemedicine to smart cars, digital homes and industrial monitoring, the explosive growth of IoT has created exciting new business opportunities for real time calls and messaging. In his session at Internet of @ThingsExpo, Ivelin Ivanov, CEO and Co-Founder of Telestax, will share some of the new revenue sources that IoT created for Restcomm – the open source telephony platform from Telestax. Ivelin Ivanov is a technology entrepreneur who founded Mobicents, an Open Source VoIP Platform, to help create, deploy, and manage applications integrating voice, video and data. He is the co-founder of TeleStax, an Open Source Cloud Communications company that helps the shift from legacy IN/SS7 telco networks to IP-based cloud comms. An early investor in multiple start-ups, he still finds time to code for his companies and contribute to open source projects.
The Internet of Things (IoT) promises to create new business models as significant as those that were inspired by the Internet and the smartphone 20 and 10 years ago. What business, social and practical implications will this phenomenon bring? That's the subject of "Monetizing the Internet of Things: Perspectives from the Front Lines," an e-book released today and available free of charge from Aria Systems, the leading innovator in recurring revenue management.
The Internet of Things will put IT to its ultimate test by creating infinite new opportunities to digitize products and services, generate and analyze new data to improve customer satisfaction, and discover new ways to gain a competitive advantage across nearly every industry. In order to help corporate business units to capitalize on the rapidly evolving IoT opportunities, IT must stand up to a new set of challenges.
There’s Big Data, then there’s really Big Data from the Internet of Things. IoT is evolving to include many data possibilities like new types of event, log and network data. The volumes are enormous, generating tens of billions of logs per day, which raise data challenges. Early IoT deployments are relying heavily on both the cloud and managed service providers to navigate these challenges. In her session at 6th Big Data Expo®, Hannah Smalltree, Director at Treasure Data, to discuss how IoT, Big Data and deployments are processing massive data volumes from wearables, utilities and other machines.
P2P RTC will impact the landscape of communications, shifting from traditional telephony style communications models to OTT (Over-The-Top) cloud assisted & PaaS (Platform as a Service) communication services. The P2P shift will impact many areas of our lives, from mobile communication, human interactive web services, RTC and telephony infrastructure, user federation, security and privacy implications, business costs, and scalability. In his session at Internet of @ThingsExpo, Erik Lagerway, Co-founder of Hookflash, will walk through the shifting landscape of traditional telephone and voice services to the modern P2P RTC era of OTT cloud assisted services.
While great strides have been made relative to the video aspects of remote collaboration, audio technology has basically stagnated. Typically all audio is mixed to a single monaural stream and emanates from a single point, such as a speakerphone or a speaker associated with a video monitor. This leads to confusion and lack of understanding among participants especially regarding who is actually speaking. Spatial teleconferencing introduces the concept of acoustic spatial separation between conference participants in three dimensional space. This has been shown to significantly improve comprehension and conference efficiency.
The Internet of Things is tied together with a thin strand that is known as time. Coincidentally, at the core of nearly all data analytics is a timestamp. When working with time series data there are a few core principles that everyone should consider, especially across datasets where time is the common boundary. In his session at Internet of @ThingsExpo, Jim Scott, Director of Enterprise Strategy & Architecture at MapR Technologies, will discuss single-value, geo-spatial, and log time series data. By focusing on enterprise applications and the data center, he will use OpenTSDB as an example to explain some of these concepts including when to use different storage models.
