Acquisition Archetypes Seen within the Wild, DevSecOps Version: Cross-Program Dependencies


This submit examines issues that come up from a shared DevSecOps platform. As a result of a DevSecOps platform and power pipeline is just too advanced and costly to create and handle individually for every program, the platform typically must be a shared functionality. This case creates dependencies and cooperation points.

These issues are examples of an acquisition archetype, which is how we check with a sample of organizational system behaviors which were seen in the course of the SEI’s experiences in conducting invited unbiased technical assessments (ITAs) on technical and programmatic points of the DoD acquisition applications. In these ITAs, program administration workplace (PMO) workers, contractor workers, customers, and different exterior stakeholder organizations present open and candid responses below the situation of anonymity that present the SEI crew perception into what is actually taking place in a program. These insights counsel that comparable, recurring issues in software program acquisition and growth—archetypes—come up throughout separate and seemingly dissimilar applications.

A earlier SEI Weblog submit examined an archetype of clinging to the outdated methods. On this submit, I focus on the recurring drawback of cross-program dependencies. I describe the conduct within the context of a real-world state of affairs and supply suggestions on recovering from and stopping future occurrences of this drawback.

About Acquisition Archetypes

Our use of the phrase, “acquisition archetypes” relies on the extra common notion of system archetypes and is supposed to explain recurring patterns of failure noticed in acquisition applications to boost consciousness, together with offering approaches to mitigate or keep away from these antagonistic patterns. The incentives that drive these patterns are comparable throughout applications and have a tendency to drive comparable behaviors.

Cross-Program Dependencies

Generally a company could must construct a brand new widespread infrastructure functionality. As an example, a company would possibly deploy a DevSecOps platform and power pipeline (e.g., compilers, code scanners, containers, and orchestration) that’s too advanced and costly to create and handle individually for every program or venture. These applications or tasks may be reluctant to just accept an exterior dependency on the infrastructure program providing a standard infrastructure functionality, resulting in inside pressure. If the widespread infrastructure has points reminiscent of poor efficiency, problem of integration, incapability to totally carry out its perform, or unavailability in the course of the required timeframe, the tasks offering and supporting that functionality are more likely to change into disenchanted or reluctant to proceed to help the infrastructure, and should criticize and even undermine it. For instance, present applications migrating to make use of the infrastructure may be aware of utilizing a specific model-based programs engineering (MBSE) software or a code scanner that implements a particular set of scanning guidelines. Making the change from utilizing the software they’re aware of to utilizing a wholly completely different software can have each up-front prices when it comes to modifications to the instruments and the system, and longer-term prices as customers should study new methods to perform the identical impact.

Tasks utilizing DevSecOps infrastructure will typically must make important modifications to their parts of the potential to accommodate the brand new infrastructure (e.g., modified interfaces, further performance, or architectural variations). Supporting the brand new infrastructure will make their very own work more difficult, require further effort and assets, adversely have an effect on their present programs, and require rework of points of these programs. Consequently, these tasks have little incentive to totally help the brand new system. Reasonably than being a win-win throughout the group, the widespread DevSecOps infrastructure could change into primarily a win for headquarters on the expense of the opposite tasks.

Report from the Subject

The best way a program is established impacts the power of a number of, semi-independent organizations to cooperate to realize a standard purpose (Determine 1). In the middle of supporting acquisition applications, the SEI typically encounters and should assist handle a lot of these organizational points. In a single such dialog a program chief mentioned, “Some applications get involved after they have dependencies on different applications. It’s an issue when completely different teams management completely different providers, and also you don’t have all of it below your management…. The infrastructure program asks us for stuff, and typically there’s funding, and typically there isn’t.” One other chief said that, in delivering capabilities, “Completely different organizations are in cost, funded individually, with completely different budgets, and they also’re required to ship towards necessities that don’t consider issues they may need.”

Determine 1: The best way a program is established impacts cooperation towards a standard purpose.

In a single case, “[a] PMO wasn’t ready for the inevitable bow wave of latest work that was coming their manner. They didn’t like being informed what to do [by a higher authority akin to a program executive office or PEO]. That created some rivalry.” This case typically devolved into finger pointing, fairly than producing outcomes: “The completely different organizations concerned all must work collectively to share necessities and make choices—however nobody owns it, in order that they blame one another.” If the directing authority had been capable of provide schedule aid and/or funding for the extra work, it may not have been seen by the PMO as primarily an “unfunded mandate.”

On this case there was a misalignment of targets that every completely different group was making an attempt to realize. One official noticed, “The motivation at our program workplace is to satisfy price and schedule efficiency, whereas the infrastructure program is about functionality supply and high quality. Subsequently, the connection mismatch distracts from effectivity.”

Evaluation

Organizational tensions can happen as a result of reluctance of applications to just accept an exterior dependency on one other program that may assist to supply a standard infrastructure functionality. The causal loop diagram (CLD) in Determine 1 represents a number of interacting applications and exhibits that the way in which one program is established can have an effect on its skill to cooperate with different applications as all of them attain towards a standard purpose. The leftmost loop (in inexperienced) exhibits that the much less in a position the “consuming” program is to realize their targets by themselves, the extra they want the shared infrastructure. The rightmost loop (in gold) exhibits that when a “producer” group is tasked to supply shared infrastructure for a number of applications however is unable to satisfy the entire “shopper” organizations’ expectations, the shoppers could change into dissatisfied and determine to assemble their very own non-public or customized variations of the infrastructure as a substitute. Nevertheless, the center loop (in purple) exhibits how doing so usually undermines the specified diploma of interoperability the shared infrastructure was meant to allow. Setting up a number of, less-interoperable, non-public variations of the infrastructure prices considerably greater than a single shared model, utilizing up funding that might have been spent to construct the shared infrastructure. These non-public variations are the results of needing a right away profit (eradicating the dependency) that can price everybody else—but when everybody does the identical factor, everybody finally ends up worse off as a result of further growth prices, non-standard programs, and schedule spent in growth and rework of the outcomes. It is a balancing loop, which oscillates round an equilibrium worth as help for the infrastructure grows after which wanes. Observe that the static mannequin described by this CLD doesn’t predict how this dynamic will play out in all circumstances however does describe the way it typically ends with shopper applications opting out of the shared infrastructure association if they will.

Options and Mitigations

A public good is an economics time period for a service that’s made out there to all members of a group the place use by one member doesn’t preclude its use by others. For instance, our nationwide protection itself is a public good for all residents. The dynamic of manufacturing a public good in human organizations has been researched extensively and has a big set of ordinary options. The event and provision of widespread infrastructure, reminiscent of a DevSecOps platform, is a sort of public good that’s topic to cooperation issues from cross-program dependencies.

In coping with cooperation issues, there are three courses of options: motivational, strategic, and structural. These are broadly characterised as follows:

  • Structural: Reframe the issue and guidelines so that individuals should behave extra cooperatively as a result of there’s formal authority behind, and enforcement of, the principles (e.g., penalties, legal guidelines).
  • Strategic: Give individuals a rational and self-interested purpose (i.e., incentive) to behave extra cooperatively.
  • Motivational: Make individuals really feel in another way in order that they need to behave extra cooperatively.

The cross-program dependencies dynamic might be managed by management that may acknowledge these dependencies as they come up and take steps to mitigate them. Nevertheless, on this state of affairs the management would should be at or above the PEO stage, and the anticipated antagonistic ramifications of the difficulty would should be raised to their consideration by a number of of the applications concerned. Hierarchical, authority-based organizations such because the navy take this strategy, though normally after dialogue with the affected events. It’s a structural answer, also known as “regulation by an authority,” but it surely requires having an authority to impose the principles, might have enforcement of compliance, and should encourage resistance from these it’s imposed upon.

If a standard infrastructure program has overarching authority over the tasks offering supporting capabilities, it will probably handle lots of the points famous above. Nevertheless, the way in which such authority may very well be granted would range considerably all through the DoD, and in some circumstances could not all the time be doable. When it is doable, it could additionally occur that such authority is overused, even when the infrastructure program has the most effective of intentions in exercising it. The authority may override the wishes or wants of the collaborating tasks; for instance, it’d power collaborating applications to implement unfunded and even undesirable mandates.

Wherever doable, the authority of the widespread infrastructure program ought to be exercised in win-win preparations that attempt to present worth in each instructions, to each events. Win-win relationships can contain offering the supporting tasks what they need (e.g., funding or assets), fixing points they may have by offering organizational experience, providing specialised coaching or help that they want, and/or discovering methods to burnish their popularity.

The second solution to handle cross-program dependencies is thru strategic approaches, reminiscent of organising a significant incentive that rewards cooperation to drive profitable joint end-to-end outcomes for customers. These approaches are weaker than structural approaches, however can be utilized to enhance them and embrace:

  • establishing cross-fertilization/cross-functional groups (exchanging individuals to interrupt down limitations and encourage cooperation)
  • creating extra interdependencies (encouraging individuals to work collectively out of necessity).

The third solution to handle cross-functional dependencies is thru much less formal motivational approaches. These approaches attempt to mitigate lack of belief and cooperation among the many completely different tasks supporting the widespread infrastructure by utilizing actions that assist preserve or rebuild belief. Whereas weaker than both of the opposite two, these will also be used to enhance structural and strategic approaches. Doable motivational approaches for addressing the conduct may embrace:

  • Consciousness: Improve the attention of the issue and talk the significance of everybody making a distinction to resolve it.
  • Proof of high quality: Present compelling proof that the services or products will work as marketed earlier than asking organizations to help it or assist pay for it.
  • Setting expectations: Encourage voluntary cooperation in settings during which persons are extra more likely to be public-minded on account of historical past and custom (e.g., Peace Corps or Battle Bonds).

The Outlook for Cross-Useful Dependencies

On this submit, I’ve investigated one recurring program conduct associated to the introduction of DevSecOps: cross-functional dependencies. DevSecOps is a strong strategy that raises new issues round cross-functional dependencies. The complexities of DevSecOps can require applications to make infrastructure modifications that may have important downstream results for different applications and tasks. By growing mutually helpful options, the authority of the widespread infrastructure program can encourage cooperation and higher conduct.
