Application Archetypes and Management

In general, there are six different types (archetypes) of line of business (LOB) applications prevalent in modern corporations today: Rich Client Applications – Applications of this type are usually developed as stand-alone applications with a graphical user interface that displays data using a range of controls. Rich client applications can be designed for disconnected and occasionally connected scenarios because the applications run on the client machine. Web Applications – Applications of this type typically support connected scenarios and can support different browsers running on a range of operating systems and platforms. Web applications have no client-side scripts or components. Web servers only serve HTML to the client. Rich Internet Applications (RIA) – Applications of this type can be developed to support multiple platforms and multiple browsers, displaying rich media or graphical content providing a higher fidelity of user experience than traditional web applications. Rich Internet applications run in a browser sandbox that restricts access to some devices on the client. Services Applications – The basic goal in this type of application is to achieve loose coupling between the client and the server. Services expose business functionality, and allow clients to access them from local or remote machine. Service operations are called using messages, based on XML schemas, passed over a transport channel. These applications may be part of a service-oriented architecture (SOA) or just a bunch of web services used for specific application solutions. Mobile Applications – Applications of this type can be developed as thin client or rich client applications. Rich client mobile applications can support disconnected or occasionally connected scenarios. Web or thin client applications can support connected scenarios only. The device resources may prove to be a constraint when designing mobile applications. Cloud-based Services/Applications – Applications in this space describe deployed services into either a private or public cloud infrastructure. Many organizations naturally have a combination of most or all of these (maybe not cloud services/applications yet!), some of which are packaged applications, while others are developed in-house. So, here’s the question: are the populations of the different types of applications random or are there patterns to the types of applications determined by some set of drivers? From what I’ve discovered, management concerns drive many of decisions to deploy applications of specific types, namely Web applications. Arguably, these types of applications enjoy low deployment effort and cost compared to other types of applications that require components to be installed on some client device. The services that comprise web applications can also be centrally monitored without having to track utilization, configuration, and failures on client computers for the most part. The downside of these applications is that they tend to have low fidelity of user experience compared to any other type of application. Now, if you’re an optimist, Rich Internet Applications (RIA) have the best of both worlds between providing a rich user experience and having a relatively thin client footprint, in some case relying on a user experience engine such as Microsoft Silverlight . On the other hand, the pessimists out there would claim that RIAs introduce client deployment and management overhead that present significant associated costs. The other types of applications have their own management overhead regarding deployment, configuration, and monitoring. In subsequent posts, I’ll address some of those issues. In the meantime, let me know what you think? Is your organization deploying a preponderance of web applications with a trend toward RIAs? Or, do you have some other type of profile? If so, why? Inquiring minds want to know. All the best, Erik

SOA Adoption Blockers: Service Management is Key

Successful adoption of Service Oriented Architecture has been a topic of discussion pretty much since the beginning of its introduction to enterprise businesses five or six years ago. As companies have worked to adopt this approach to building more reliable and agile applications at a lower price, they quickly found that it wasn’t as easy as it was to build the monolithic applications of old or even the n-tier and Internet applications that became standard archetypes in the late 1990s. While those types of applications certainly require solid application development, deployment, and management discipline, SOA introduces several new dimensions to the challenge of successfully adopting applications built on this architecture. Applications that rely on SOA have two inherent attributes that do not necessarily exist within applications based on other architectures. First, the architecture promotes the composition of ever-smaller atomic services into higher-order services (a ProcessOrder service, for example, has ValidateCustomer and CheckCredit services associated with it). This “feature” introduces the potential for hundreds or thousands of these compositions to exist in the enterprise (or, in some cases, outside the organization’s firewall; more on that in a subsequent post). Second, services based on SOA are autonomous and stateless by nature (or, at least, they should be!). As such, they can be created and exposed by anyone in the organization as a completely independent island of functionality without being tied to any one specific application. While both of these elements of SOA can certainly benefit enterprises who wish to accelerate the creation of custom, line-of-business applications through the promise of service reuse, the dark side is that services can proliferate out of control. Adopting SOA doesn’t inherently enforce reuse. Corporations may have multiple versions of a “CreditCheck” service created by different departments. Further, these services don’t necessarily have well-defined service levels defined for them that are backed up with enforceable service level agreements. While this may not be a significant problem initially, it can be a serious concern to organizations that want to adopt SOA as a strategic direction within IT. The nature of application development and maintenance changes since the development cycles, feature requirments, and service level requirements become decoupled. While there are many potential impediments to SOA adoption, which I will post more on later, the discipline of governance and the implementation of robust service management is central to long-term sustainability of applications that rely on the services within an SOA. Here’s why: Many organizations view service orientation as overly complex, without enough supporting tools to properly manage service artifacts. There is an inconsistent use of repositories and/or registries for defining service levels, availability requirements, and providing adequate discoverability (for a good description of repositories and registries, see Keith Pijanowski’s article on this. Policy enforcement at run-time in many cases is non-existent or is spotty at best. Good service orientation mandates a consistent approach to data access. This implies that data management, including master data management (MDM), consistent access to structured data (as stored in a DBMS), semi-structured data (as you might find in search service such as SharePoint), and unstructured data (as exists on a file share), must be taken into consideration. Security and privacy must also have a strong focus. Metrics definition and reporting is elusive. While specific services on individual servers can (and often are) monitored, having an all-up view of a related set of services that provide a business view of the health of the application is an altogether different beast to tackle. Production testing and troubleshooting gets harder to implement. As services proliferate, a failure at any point along the way will be harder to pinpoint and diagnose, particularly if the failed service is part of one or more composite services. Subsequent posts will delve into each of these as well as other adoption issues. For now, we’d like to get your feedback on the list above and the subject of service management. What resonates with your experience and what doesn’t? In particular, I’m curious about whether application performance issues represent an impediment to SOA. In my experience, this hasn’t bubbled up as a tier one issue, but I invite you to prove me wrong. All the best, Erik, Application Platform lead, War on Cost Team

Welcome to the IT Business Value Blog

Happy New Year and Welcome to the IT Business Value Blog. Like others within program management at Microsoft, our team of strategic program managers (PM), including Elliott Morris, Bruce Gary, Brett Williams, and I, work within the Windows Server & Tools division at Microsoft to help shape the future of the Microsoft platform. However, unlike our peer PMs who mostly focus on particular product feature design, our focus is different in that we focus more on identifying business value enablers and inhibitors across various customer segments to better understand what our customers need from the future versions of Windows, our management platform with System Center, and our Application Platform.

New Home for Projectified

I will be moving Projectified to the following address: The same FeedBurner RSS feed  ( ) should still work as I changed its settings to point to the technet blog. This site will stay up for a long time or until I can figure out how to bulk export the posts from here and import them into the TechNet blog.

Deployment Practices: Required Fields

Few things are more frustrating then using a system and being presented with a field you MUST fill in to continue at a time when you don’t know which value is appropriate for that field. Project Server is no exception. You can make any enterprise custom field in Project Server a required field. At the project level this means that a project cannot be saved until each of these fields contains a value. This is great if you know for sure that the project manager will always know which value to pick from the list at the time they first save their project. But if they don’t you have a couple of things that are going to happen and you need to be prepared for them and decide if they are your intended consequences. The project manager will NOT save their project until they find the answer (remember that the answer COULD be several days away.) Do you really want the PM to NOT save the project because they don’t have the answer to this one field? Where will they start their planning in the mean time? Where will their data go? The project manager will pick one of the values from the list just so they can save the project even if that value is not right. Remember that they may not remember to come back and fix it when they have the right information! The project manager will curse you (the administrator) and pray to their God that you be injured in some way very soon. Number 3 is going to happen for sure, count on it. What you have to decide is if you want number 1 or number 2 to be happening while your curseinjury takes place. The easy way to avoid all three is to either NOT make fields required unless you 100% sure that the project manager will know which value pertains to their project OR provide them a “Not Yet Known” value in the lookup table. I tend to prefer the “NOT YET KNOWN” option. It allows your views and reports to show which projects have complete field profiles and which projects are in need of more complete data. Just make sure that the people you have creating reports and views know to allow for this value in their filters. This means that if you want to show all projects where a field equals “X”  or “Y” that it should also contain projects where it equals “Not Yet Known” because those projects MIGHT be “X” or “Y”, we just don’t know yet. 🙂   Technorati Tags: Project Server , EPM

On the RADAR

OK it has been a while. I have been doing a bunch of the normal consulting thing these past few months. Helping customers better understand how to configure their Project Server environments around their business processes (and often helping them understand how their business processes might be changed to take better advantage of features.) I have also been doing some side-work projects. Working again on putting more meat on the bones for a framework for iterative designbuild loops for early rolloutproof of concept phases in Project Server deployments. The early stages of an addin for Project Server that would allow administrators to control which projects a security category allowed access to based on some defined set of project level criteria. 1 is something that has been kicking around for a long time and I hope to get moving on soon. 2 is much more recent and I think also more exciting (which means it will likely get done first.) It would allow you to have a category that would give permissions to projects based on the value in a project level custom field rather than just on relationships to the project. Email me your thoughts on either of these if you care to share them. I will be better about updating. 🙂 Technorati Tags: Project Server

WIP for Knowledge Work

I saw this post at Learning about Lean via Frank's Focused Performance blog and it speaks well about the issues we all face as consumers of data and information. But more importantly it made me think about WIP for the first time since I was doing process and project management work at Boeing in 1996-1997. I thought a lot about it then when I was dealing with manufacturing but not so much since then as I have been doing 'info work.' The thing it made me to tonight was to think about not just my inbox (as Joe Ely mentions directly) but also about the partly finished “things” I have laying around and the creative price of not having all of them done. It made me think about the partly finished specs for Project Server addin's that I had to put aside for other more pressing commitments and it made me think about the half incubated ideas for papers and blog posts that I scrawled down when I was on a plane or in a meeting and an idea hit me but I had no time for finishing it out. I think the real price is that as I go back over some notebooks and OneNote sections that hold these seeds I am struck by how complete I remember the thought being when I made the note and how incomplete I think they are NOW. I have lost something between then and now. I'm pretty sure I can get it back but how long am I going to have to think about each of these ideas to get back to where I was 2 months ago? So what I took from Joe's post (even though it was not what he wrote about exactly) was that I need to do a better job of documenting what I know will become long term on-hold WIP so that when I get the chance to get back to it I will not have to spend hours rethinking it to get back on track with it. You all have these on-hold projects sitting around in notebooks and in Word documents. How many of them are in a state where you could pick them up right now and start working on them without a lot of re-publishing and rethinking? Think about it.

What's in Your Bag?

I have seen these posts in a few places so here is mine. Here is a list of everything in my Laptop bag: Timbuk2 Large padded laptop bag . There are two sizes, get the bigger one. I have also noticed that Timbuk2 started making a version of this bag out of a lessor material. Mine has a backing on the inside of the outer material that is waterproof. The new ones do not have this. Not sure it matters since I’m not planning on getting it wet. 🙂 Great bag! Holds everything and is tough. I have had this bag almost a year and it looks brand new!
